mud and snow
M+S is an acronym for “mud and snow.” It’s a branding found on the sidewall of some all-season tires. It’s important to note there is no actual testing or accreditation to earn the M+S label.
What does m+s Mean on tires?
M+S Tire Marking on All-season Tires. M+S symbol usually found on the side of the tire near the wheel flange. The M+S tire marking system was first introduced to differentiate knobby bias-ply tires from the more common rib treads on early radial car and light truck tires.
What do the markings on tires mean?
Tires are an essential part of any vehicle, and it is important to know what all of the markings on them mean. The “M+S” mark on tires stands for mud and snow. This means that the tire is designed for use in both off-road and winter conditions.
Are M+S tires better?
While M+S tires can offer better performance in challenging conditions, they is not necessarily the best choice for every driver. Tires are an essential part of any vehicle, and it is important to know what all of the markings on them mean. The “M+S” mark on tires stands for mud and snow.
What does p mean on a tire?
In this example, the “P” in this tire size stands for Passenger. It could also read “LT” for light truck, which means the tires are designed for a heavier vehicle like an SUV or pickup truck. 205 – The next set of three numbers make up the width of the tire sidewall.
Passenger Tire
P identifies your tire as a Passenger Tire. The P stands for PMetric. If your tire size starts with LT rather than a P than it identifies the tire as a Light Truck tire.
What does XL mean on a tire?
extra load
XL (or Reinforced) tyres are ‘extra load’ tyres – they indicate that a tyre is reinforced to be able to withstand a higher load than other tyres of the same size. This is done through a number of ways, but most usually by adding strengthening material to either the tyre’s bead or face.
What does XL mean on tyres?
A reinforced or XL (extra load) tyre is a specially reinforced tyre which carries heavier loads than tyres of the same size. These types of tyres are stronger and more hardwearing than standard tyres, and are often used for large vehicles that carry heavy loads or large family cars, such as 4x4s.
Why are XL tires called extra load?
Hence the name “Extra Load.” Because of this, they tend to be used in situations that require a higher load capacity or better tire safety. If a tire is an XL model, it will be noted on the sidewall in one of these ways: Extra Load, XL or Reinforced.
Are XL tires out of date?
Extra Load (XL) or reinforced tires have a higher price tag than regular ones. If you have Extra Load (XL) or reinforced tires on your current set, they could be out of date. Check tire pressure regularly. Extra Load (XL) or reinforced tires may show wear over time and require replacement sooner than regular ones. Do XL tires ride rough?
What vehicles need XL tyres?
In combination with a higher tyre pressure, XL tyres have a greater load-bearing capacity and are particularly suitable for use with minibuses, off-road vehicles and SUVs. Which vehicles need XL tyres? Remember these three important points when choosing tyres: The tyre size you should use is easy to find out.
What does LT mean on a tire?
Light Truck-metric
An “LT” on your sidewall before that long string of numbers and letters denoting your tire size signifies the tire is a “Light Truck-metric” size; it was designed for use on a vehicle that carries heavy cargo loads or tows a large trailer.
What are Lt tires?
LT stands for “light truck,” which refers to a particular class of passenger tire, but the goal of designing LT tires is for very specific heavy-duty tasks. An LT tire is essentially a reinforced tire with thicker, stiffer sidewalls and a deeper tread compared to the p-metric tire commonly used for passenger vehicles.
Are Lt tires better than passenger tires?
While LT tires are more expensive than passenger tires, they are more durable because they have extra material under the tread and in the sidewall that protects the tire from damages. Additionally, manufacturers often add extra steel belts, thicker rubber, and a deeper tread on LT tires. Read More: How Long Do Off-Road Tires Last?
What is Lt sizing?
Most passenger tires today have metric or “P-metric” sizes. These are the sizes most of you are probably familiar with, such as 205/55R16. But there’s another system of sizing out there, LT Sizing, used primarily for light truck and off road tires. LT sizes can be confusing because they’re so different from the sizes you’re used to seeing.
How do I know if my tires are Lt?
As a first-time car owner, you might not know how to read your tire in the initial stages. So how do you know your tires are LT? If you look at your tire sidewall, you’ll see a DOT serial number and some numbers that represent details of your tire size from the aspect ratio, diameter, and load capacity.
What does ZR mean on tires?
The letters ZR on the sidewall relate to a tyre’s speed rating, which in this case is 150mph. That means it should not be driven at speeds in excess of 150mph (240kmph) – of course, where such speeds are even legal! Before 1990, ZR was used for high-performance tyres.
What does p mean on a car tire?
Most car tires have the letter “P” at the front of the tire size. This letter signifies that it is a P-Metric tire designed for the standards of passenger vehicles. If you see the letters “LT” instead, it means Light Trucks. Tire manufacturers design these for the higher inflation needs required by some trucks.
Are Lt tires P Metric?
Tire sizes that have a “p” in front of the numbers in the size description, or no letter at all, are p-metric. If there is an LT in front of the size, then it is an LT tire. Which tire type is right for you depends on how you use your vehicle. Occasionally tires have a “p” listed in front of the tire size.
What does the first letter in a tire size mean?
The first character (s) in a tire size designate the tire’s class. In this example, “P” indicates that the tire is a passenger car tire. An “LT” before the tire size designates a light truck tire, and no letter before the size indicates that it is a European metric tire.
How do you know if a tire is a passenger car?
The first letter in the tire code lets you know the type of vehicle the tire is intended for. The most frequent type is P for passenger car, followed by LT for light truck. 2. Tire Width The three-digit number immediately following the vehicle type letter (s) tells you how wide your tire is.
What is R and D in tyres?
The main task of R&D is to support the company’s status as the manufacturer of the world’s best winter and forestry tyres.
What does R Mean on a tire?
R indicates the construction used within the tires casing. R stands for radial construction. B means belted bias and D stands for diagonal bias construction. 17 The last dimension listed in the size is the diameter of the wheel rim, which is most often measured in inches. What’s the difference between 205 and 235 tires?
What is a D rated tire?
D-rated tires are classified under load range D. Built for light trucks, they have a maximum pressure of 65 PSI (450 kPa). They also have an 8 ply rating which enables them to be inflated and maintain their round shape. D-rated tires only provide more capacity if they are inflated to the higher-rated design pressure.
What do digits mean on a tyre?
These digits express the height of the tyre sidewall expressed as a percentage of the tyre width. In this example, the tyre height is 55% of its width. The letter ‘R’ indicates that the tyre is of radial construction, as most tyres manufactured today are. Other types of construction include ‘B’ (bias belt) and ‘D’ (diagonal).
How do you know if a tyre is radial?
Next up is a letter. This tells you how a tyre is constructed. In this example, the “R” means that the tyre has radial construction. This is where the internal ply cords extend across the casing from bead to bead, in a radial direction. Less common tyre constructions include diagonal or bias ply, represented by the letter “D”. 4.
What is Q or S on tires?

What is a Q rating on a tire?
Tires with a Q speed rating can safely sustain speeds of up to 99 miles per hour. The tire may be able to reach higher speeds, but going faster than 99 mph for any length of time is not safe. The tire is not designed to handle the stresses. What is a Z Rating? For tires rated above 149 mph, a Z rating may appear in the size designation.
What is the difference between a Q and s speed tire?
A Q speed-rated tire is designed to be driven up to 100mph because it can’t endure the stresses associated with speeds higher than that. On the other hand, an S speed-rated tire is better as it can endure heat and friction levels generated by speeds up to 112mph.
What do the letters ‘R’ and ‘s’ Mean on tires?
The letters R, Q and S represent the speed rating. Speed Rating (Q) indicates the tire is approved for speeds up to 99mph under optimal conditions. Speed Rating (R) is approved for speeds up to 106mph and Speed Rating (S) up to 112mph under optimal conditions.
What does a T rating mean on a tire?
A T rating indicates the tire is approved for speeds up to 118 mph (190 km/h) under optimal conditions.

An H speed rating indicates the tire is approved for speeds up to 130 mph (210 km/h) under optimal conditions.
What is G or H rated tires?
Most tires for trucks today are rated G or H. “Based on the size, most G-rated tires can hold approximately 6,000 pounds, while an H-rated in the same size can hold roughly 6,500 pounds at the same pressure per tire,” said Rob Williams, senior director of TBR sales at Hankook Tire.
What is a h speed rated tire?
H speed ratings are common in the grand touring all-season tire category. A W means the tire is approved for speeds up to 168 mph (270 km/h) under optimal conditions. W speed rated tires land firmly at the performance end of the speed rating spectrum. Ws are suitable for performance coupes and sedans, and even street driven exotic sports cars.
How do you know if a tire is H rated?
The rating is the speed the tire has been tested to for continuous safe driving. The English equivalent speed for H-rated tires is 130 mph and V-rated tires are good for up to 149 mph. There are two ways the speed rating will be indicated on the tire sidewall. The older method puts the speed rating next to the “R” for radial in the size.
What are G rated tires?
Typically, G-rated tires refers to the stronger tires commonly used for trailers and RVs. The exact amount of weight these tires can hold varies. However, it is usually around 4,000 pounds each. However, G-rated tires can also refer to the speed rating of the tire. These tires can go up to 56 mph, which typically isn’t enough for most drivers.
What is W and Y in tyres?
Confusingly, W-rated tyres are rated at a higher speed in excess of 168mph. Y-rated tyres are rated in excess of 186mph. See the full list below. Tyre speed ratings should be matched to the official top speed of your car. If you fit cheaper, lower-speed-rated tyres, it could affect your car insurance.
What is the difference between W and y speed tires?
W speed-rated tires are able to withstand speeds up to 168mph or 270kph, and they tend to be slightly better when it comes to longevity, comfort, winter driving, and price. On the other hand, a Y speed-rated tire can go 186mph or 300kph which is certified supercar territory.
What does a W tyre rating mean?
Essentially, it means that your tyres will be able to handle a specific maximum speed while carrying a load. Typically, tyres with a W rating can handle a maximum speed of 168 mph. However, it is important to keep in mind that your tyre rating does not necessarily indicate the top speed that your vehicle is cable of reaching.
Can you mix y speed rating tires?
Mixing tires with different speed ratings is a prime example of something you shouldn’t do. So, W vs Y speed rating tires? A W speed-rated tire is good for up to 168mph or 270kph which means that you can safely drive these tires up to those speeds.
What does h mean on a tire?
In earlier incarnations of the speed rating system, “H” stood for “hhigh performance,” which is why it maintains an unusual position in the speed rating spectrum today. Once the highest speed rating a tire could have, “V” used to represent a maximum of 149 mph (240 kph) or more. Nowadays, it means 149 mph but no higher.
Are M S tires good for summer?
Mud and snow tires are excellent options for driving in muddy or icy conditions. Remember, however, that they don’t perform as well in warm temperatures. The soft rubber, although resistant to hardening in cold conditions, is less ideal in warm weather.
What are the best summer tires for m+s?
My goto for cheap summer tires were the BF g-force sport 1. They were usable in the winter and light snow when I was too lazy to change out. The compound is for summer so it will not work well when cold, but the tread design meets the most basic requirments for M+S. Does not mean they will work well in M+S, just meet basic Gov standards.
Are M+S tires all-season?
M+S tires are not all-season tires. They are winter tires. They are made of a softer rubber than all-season or summer tires, which makes them less durable, but better for traction in the snow and ice. Their tread pattern is also designed to channel away water and snow from the tire contact surface so that the tire has more grip on the road.
Do summer tires make a difference?
A: Putting summer tires on your car can absolutely make a difference. With specialized dry weather tread patterns and different rubber compounds than all-season or winter tires, summer tires improve your precision on the road. They can also increase your car’s responsiveness, cornering, and braking.
When should you replace your summer tires?
Hotter weather and longer days in the summer are when you need to think about replacing a new tire. While all-season tires maintain average performance on dry or wet roads, the best summer tires should be your top priority if you want to maximize your vehicle’s performance.
What does M and S mean on a car tyre?
mud and snow
M+S means mud and snow. This marking indicates that the tyre is better suited to snowy or muddy roads than standard models (summer tyres). Be aware that this marking does not require passing a certified test and is entirely up to the manufacturer.
What does m+s Mean on a tyre?
Some tyres are marked with M+S on the sidewall, including all-season and winter tyres. These letters simply stand for the words “Mud” and “SSnow” and indicate that the tyre is, according to the manufacturer , a “snow” tyre. However for tyres with only M+S markings performance under winter conditions is not subject to regulatory testing.
What do tyre markings mean?
These tyre markings are usually composed of a letter and a number. The letter, R, indicates that the tyre’s internal construction is Radial. Radial technology, invented by Michelin, uses combinations of rubbers and metal and textile reinforcing materials to form very robust structures in the tread area but flexible sidewalls.
What is the difference between M+S and mud + snow tyres?
The snowy surface is just one of the cases. Mud + Snow tyres are often used for cars that drive a lot on non-surfaced roads, primarily for off-the-road vehicle and pickups. On the other hand, M+S tyres tend to hold the road worse when manoeuvring at speed, especially on dry and clean asphalt.
Are all winter tyres m+s?
This may be misleading. When buying tyres, remember that “M+S” is marked on all winter tyres, but not all tyres with “M+S” marking have winter properties (see the graphic below). You will also find “M+S” letters on some all season tyres.

Are M & S tires as good as winter tires?
Winter tires are specifically designed to provide traction in deeper snow and in sub-zero temperatures. Mud and snow tires will perform just fine in lighter snow but, if you regularly drive in snowy conditions at temperatures lower than 7°C, you’re better off with a set of good winter tires.
Can I use M and S tires in the winter?
M+S tires are a viable option for motorists who live in areas without frequent winter weather and who plan their trips to coincide with periods of better weather. All drivers should be prepared to drive with added care and caution when winter conditions are encountered.
Are M+S tires the same as winter tires?
M+S tires are not the same thing as winter tires. M+S tires, or mud and snow tires, meet minimum RMA requirements for mud and snow traction. This is an important point because there are many types of winter weather including rain, slush, ice, sleet, etc. Winter tires are designed to perform well in all winter conditions.
Are mud + snow (M+S) tires safe for winter?
Are Mud + Snow (M+S) tires safe for winter? With BC’s winter tire regulations about to take effect on most routes in BC, Kal Tire is helping drivers to understand what makes Mud + Snow (M+S) tires different from winter tires, and why winter tires are much safer in cold weather conditions, including snow and ice.
Can you use M+S tires all year long?
You can use M+S tires all year long. This is accomplished by having more “tread” between the grooves of the tire. An M+S tire has more rubber on the tire between the grooves (the tread) than a “summer” or “all-season” tire would have. This makes it great for off-road conditions, but less efficient for dry roads, which decreases your gas mileage.
Do snow tyres need to be marked M+S?
European regulations on winter tyres indicate that “tyres must be marked M+S if they are snow tyres ”. No performance tests are required to display the M+S marking: this is merely a self-certification from the manufacturer. The marking does not imply any sort of objective performance guarantee.
What is the difference between M & S tires?
Mud and snow tires are all-season tires that have been approved for muddy and snowy conditions. The ‘M+S’ designation can be found on the tire. With regards to mandatory tire requirements in Canada, mud and snow tires are approved for use in British Columbia as long as the tire has a tread depth of 3.5mm.
Is an M+S rated tire better?
An M+S rated tire will have better traction on packed snow or mud, but the rating doesn’t reflect traction for wet, soupy mud, slush, ice, fresh snow or even cold, dry pavement. That said, if your area doesn’t see more than an inch or two of snow most winters, an M+S rated tire can be a great year-round choice.
