You can identify winter tires by the symbols on the sidewall. These are the M+S symbol and the three-peak mountain snowflake (3PMSF) symbol, and both are industry standards.
What do snow tires look like?
Snow tires have a mountain and snowflake symbol on the sidewall. Check out the sidewall on the outside of your tire (the area between the edge of the tread and the rim). Snow tires always have a small, 3-peak mountain symbol with a snowflake inside. [1]
What does the severe service symbol mean on winter tires?
Indicated by a pictograph showing a peaked mountain with a snowflake in the middle, the severe service symbol indicates a winter tire can handle snowy and slippery roads, as well as low temperatures, and meets the minimum requirements for providing snow traction. How winter tires earn the Mountain Snowflake symbol
What is the three peak mountain Snowflake symbol on winter tires?
Three Peak Mountain Snowflake symbol is on many Winter Tires. Recognizing a need for a more up-to-date and helpful measurement of true winter performance, as well as a way to differentiate all-season tires from winter tires, the Rubber Manufacturers Association (RMA) came up with the Mountain/Snowflake symbol for tires.
What does m+s Mean on winter tires?
Many winter tires have the M+S rating symbol on the sidewall. This stands for Mud and Snow, meaning that the tires are constructed to improve grip on muddy and snowy roads. These tires have a specific block tread pattern which helps to improve traction.
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Are XL tires out of date?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 are 3 peak tires?
WHAT DOES THE THREE-PEAK MOUNTAIN SNOWFLAKE SYMBOL ON TIRES MEAN? If you see this symbol on the sidewall of winter tires, it means they have been tested and proven capable of performing under extreme winter weather driving conditions.
What are 3 Peak Mountain tires?
Tires with the 3-Peak Mountain Symbol are typically all-season tires that use the softer rubber compound. While they might not perform as well as summer tires when the weather gets hot, you can still use them in the middle of the year. This negates the need for swapping out tires between seasons, which can cut down a lot on time and cost.
What does the 3-peak mountain symbol on a tire mean?
Here’s what that symbol means. The 3-Peak Mountain (3PMS) symbol on a tire means that it has been tested for acceleration on medium-packed snow and meets specific standards. According to Family Handyman, tires that meet the 3PMS criteria have scored at least a 110 on the traction index.
What are 3pms tires?
Although you may not have noticed, these specially-rated tires have been around for a while. In fact, the U.S. Tire Manufacturers Association and the Tire and Rubber Association of Canada developed the 3PMS symbol back in 1999. Since then, tire manufacturers are required to meet the standards for the symbols in the U.S., Canada, and Europe.
What is a three-peak mountain Snowflake?
These tires feature a unique logo called the three-peak mountain snowflake, and the little image carries a lot of weight when it comes to winter traction. What is the three-peak mountain snowflake? The three-peak mountain snowflake, or 3PMSF, means that tires meet the standards set by the United States Tire Manufacturers Association (USTMA).
What is the 3 peak symbol?
The 3-Peak Mountain Snowflake Symbol (3PMS for short) is a six-pointed snowflake inside a three-peak mountain, found on tires that meet specific standards. They signify the tire has been tested for acceleration on medium-packed snow. Braking and turning don’t factor into the testing.
What does the 3 Peak Mountain Snowflake symbol mean?
The 3 Peak Mountain Snowflake symbol indicates the tire is rated for Severe Snow Service. This is the acceptable standard for winter driving in Canada and provides improved safety on snow and ice. The M+S symbol differentiates an All-Season tire from a Summer only tire.
Is 3pms a Canadian symbol?
In fact, the U.S. Tire Manufacturers Association and the Tire and Rubber Association of Canada developed the 3PMS symbol back in 1999. Since then, tire manufacturers are required to meet the standards for the symbols in the U.S., Canada, and Europe. How do 3PMS tires differ from regular snow tires?
What does 3PMSF mean?
When you find the 3PMSF symbol on the side of a tire, it indicates the tires meet certain U.S. Tire Manufacturer Association (USTMA) requirements for severe snow conditions. The symbol is there to help you identify if a tire will provide traction on medium-packed snow.
What does 3PMSF stand for?
Such tires that have passed a specific winter traction performance test are entitled to display a 3PMSF (TThree-Peak Mountain Snow Flake) symbol on their sidewalls. Tires designed for winter conditions are optimized to drive at temperatures below 7 °C (45 °F).
What do the M+S and 3PMSF markings mean?
What do the M+S and 3PMSF markings mean? M+S stands for Mud+Snow, indicating that the tyres are suitable for use in the winter (studded or non-studded winter tyres). The official winter tyre marking is the snowflake symbol, also known as the 3PMSF marking.
What is a 3PMSF tyre?
Please notice that 3PMSF is a symbol not only for winter tyres, but also for all season models that meet certain requirements for traction in the snow. That’s why we use the term “tyre for winter conditions” instead of simply saying “winter tyre.” Many European countries introduced legal requirements for winter tyres.
Do all-weather tires have a 3PMSF?
Yeah, it is vague, but it is a laboratory test that actually tells consumers more than an M+S marking (also seen above), which is just a calculation of tread geometry. All dedicated winter tires have the 3PMSF, but an all-weather tire is suitable for winter conditions yet doesn’t necessarily have to be swapped on and off every winter and spring.
What does M and S mean on a tire?
Mud+Snow
M+S stands for Mud+Snow, indicating that the tires are suitable for use in the winter (studded or non-studded winter tires). The official winter tire marking is the snowflake symbol, also known as the 3PMSF marking. (the techinical name is ‘Servere Service Emblem”.
What are summer tires for?
Summer tires are ideal for high-performance vehicles, and are built for speed and agility. They offer increased responsiveness, cornering, and braking capabilities. This is typically attributed to specialized tread patterns and rubber compounds that allow for improved precision on the road.
What are summer tires?
Summer tires are made from a softer rubber compound and are typically fitted with large tread blocks to give maximum contact with the road in warmer weather. As a result, summer tires generally have more grip in both wet and dry conditions and provide optimal cornering and braking capabilities.
What are the advantages of summer tyres?
The main advantage of summer tyres is their optimised handling in both, wet and dry. This is partly due to the specially designed tyre tread bars. They offer you better grip length- and sideways, which is beneficial to minimising aquaplaning. Another advantage is the rubber compound. What are summer tyres made of?
Are all-season tires better than summer tires?
When it comes to winter driving, all-season tires may be more suitable than summer tires, given their blend of summer and winter performance capabilities, but we recommend considering making the switch to winter tires to get optimal traction and performance in extreme winter conditions.
What is summer rubber?
Summer rubber is for drivers who regularly take their rides to the track or who get their thrills on switchbacks and twisty roads. The every day commuter can benefit from the performance summer tires deliver, but there are more economical tire solutions for “routine” driving.
What is a true snow tire?
True winter tires have a distinct symbol on their sidewalls: a three-peaked mountain with a snowflake (3PMSF). If your tire doesn’t have this symbol, it is not a proper winter tire and will not perform adequately in cold temperatures. (To make things trickier, 3PMSF tires will also display M+S on the sidewall.)
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.
Are there letters in a tire?
Following the tire size, you will see a set of numbers followed by a letter. Let’s use 94 H as an example from our graph shown above. The first set of 2-3 numbers are the load index followed by a letter indicating the speed rating. In this case, the load index is 94 and the speed rating is H.
What do the letters on a tire number mean?
Though they aren’t part of the tire number, they’re still important factors when it comes to choosing the best tire for your vehicle and application. The tire class is indicated at the beginning of the tire code. Typically, you’ll see the letters P, LT, or ST, or no letters at all.
How do I know if my tire size is Lt or St?
Read on for some clarification. First, you will notice that your tire size will start with either a P, LT, or possibly ST. This indicates what type of vehicle the tire was meant to go on. The “P” indicates passenger car. The “LT” would be for light-duty trucks, and “ST” is for strictly trailers.
What are LT and St tires?
As you may have guessed, tire numbers that start with “LT” are light truck tires. They’re made for larger pickups and work vehicles that tow trailers. Light truck tires are designed for vehicles with a ¾-ton to 1-ton capacity. Tire numbers with an “ST” are special trailer tires. They’re used on all types of trailers from utility to fifth wheels.
How do I know what size my tyre is?
As explained on the numeric system of tires above. Some numbers indicated on the sidewall tell what size the tyre is. For most motorists the size part that matters is the width of the tire, the aspect ratio and tire diameter indicted right after the aspect ratio.
What are all-season tires good for?
All-season tires feature tread patterns and rubber compounds that make them suitable for use in wet conditions and a wide range of hot and cold temperatures. The tires are engineered to stand up to light snow, which means that drivers can use them year-round in most temperatures.
What makes a good all-season tire?
A good all-season tire has a balance of features. It should be able to perform well in a wide range of conditions. That includes hot weather, wet roads and winter weather. It should have a good tread life rating and the ride should be smooth and quiet.
Do you need all-season tires in the winter?
Certain jurisdictions across North America (including some areas of British Columbia in Canada, for instance) require all cars to be fitted with all-season tires (as opposed to summer-only tires) during the winter months. Plus, there are all- weather tires in the snow as well – something winter drivers should also look at.
Why are summer tires better than all-season tires?
Because of that sticky rubber, summer tires wear down faster than all-season tires, resulting in much shorter tread life. These tires are suitable for sports cars, performance-oriented vehicles, summer vehicles, drivers who live in warm climates (Southern California, Florida, Hawaii) and anyone who wants maximum traction in summer.
Are all-season tires rated for wet weather?
While all-season tires are rated for any kind of weather, those who live where there’s often heavy rain will want tires designed to handle all that moisture. The Firestone WeatherGrip offers not just traction in wet weather, but also features the three-peak mountain snowflake symbol that indicates it’s also rated for snow and ice.

How do you read a car tire number?
By knowing how to interpret the numbers and letters on a car tire, you can know the speed rating, temperature resistance, load index numbers, as well as the tire’s width and rim diameter. Read the manufacturer and the tire name. These are printed in large letters toward the outside of the tire.
How to read tire size in inches & metric?
There are two ways that tire manufacturers display tire size, inches and metric. How to read tire size in inches is very straight forward. Example A : 33X12.50R15 The first number is your overall diameter of the tire. In this example the tire diameter or “height” is 33 inches tall. The second number represents the width of the tire.
How do you know if a tire is wide?
The first series of three numbers tells you the width of the tire tread in millimeters. Width tread may range from 155 to 315. The two numbers after the slash show the aspect ratio of the tire. This is the tread-width percentage that is equal to the sidewall’s height. The average ranges from 55 to 75 percent in most passenger vehicles.
How do I know when to replace my tires?
Some tires may have more wear than others. Some tires have a built-in tread wear indicator. This feature can make it easier to know when your tires need to be replaced. Indicator bars are found in between your tire treads, and when the tread depth is even with the bar, it’s time to replace your tires.
What are tire symbols?
This code begins with DOT and then is followed by three sets of 4 digits, which are a combination of letters and numbers. The first two numbers represent the week the tire was manufactured. The second two represent the year. So if the DOT number is 3620, it means the tire was manufactured in the 36th week of 2020.
