I-3 (I3) – traction tread tires with a bar type treads that looks like smaller versions of R-1 drive tires. Primarily found on self propelled implements and ground powered equipment.
What are the three numbers on tire size?
The three numbers on tire size represent the width, height, and diameter of the tire, respectively. The width is measured in millimeters and indicates how wide the tire is from side to side. The height is measured in a height-to-width ratio. The diameter is measured in inches and tells you the size of the rim or wheel that the tire will fit onto.
What is a metric tire?
If there’s no letter before the first number, you have a metric tire most commonly referred to as European size. It’s also measured in millimeters but may have a different load capacity than a P or LT tire. B: TIRE WIDTH The three-digit number following the letter is the tire’s width (from side to side, looking at the tire head on) in millimeters.
What does B mean on a tire?
It’s also measured in millimeters but may have a different load capacity than a P or LT tire. B: TIRE WIDTH The three-digit number following the letter is the tire’s width (from side to side, looking at the tire head on) in millimeters. This may also be referred to as the section width.
What is the width of a tire?
This can also be referred to as the section width. In the tire size, the first three numbers refer to the width of the tire. As an example, if your tire size is P225/65R17, the width of the tire would be 225 millimeters. 3. Aspect Ratio After the slash mark, the next number you will see is the tire’s aspect ratio.
Should I buy 3 or 4 tires?
Although new front tires will spread water and maintain traction, worn tires in the back will hydroplane and may cause the vehicle to spin out, says Tire Review. This is the same for vehicles with rear-, front- or all-wheel drive. Ideally, you’d replace all four tires.
Do I need to replace all 4 tires at a time?
The answer to this question really depends on your car. Most of the cars on the road today are front-wheel-drive, and a few are rear-wheel drive. These don’t necessarily need to have all four tires replaced at once. Usually two at a time is sufficient.
How do I avoid buying more than one tire?
One way to avoid buying more than one tire is to have the tread on the new one “shaved” so it matches the depth of the others. Some tire dealers will shave off some tread depth on a special machine for a fee. If you decide to replace only one tire, the replacement should be the same model,…
Should I put new tires on the back of my car?
It’s best to replace all four tires at once, but if you must replace them in pairs, put the new tires on the back (regardless of whether the car is front- or rear-wheel-drive). This will help the car retain its stability and predictability in a panic swerve. (Older tires on the rear will make the car more likely to spin out.)
Should I buy a single tire or split a pair?
Flat tires tend to happen one at a time. The ideal scenario is to replace all four tires, but that can be costly. So to address a tread puncture or sidewall tear, can you buy just a single tire or split the difference and replace a pair? The first thing to consider is whether or not your car is all-wheel or two-wheel drive.
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 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 H mean on a tire?
“H” represents the speed rating, which is how fast the tires can go based on their load capacity. This rating ranges from A – Z. “H” indicates a speed rating of up to 130 mph.
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.
What does h mean in a tyre rating table?
As with the load index, this letter references a look-up table which indicates the maximum permissible speed of a tyre. In this example, “H” means the vehicle has a maximum speed of 130mph under the maximum load. “Although a speed rating table references the maximum speed a tyre can move under load, you should not use this as a threshold.
What is the difference between H & T tires?
H ranks higher than T in supported speed limits, with a value of 130 miles per hour or 210 kilometers per hour. You will spot tires with H on the sidewall on sedans, SUVs, and crossover SUVs. Such vehicles have a high horsepower, which translates to more speed. You will also see them on luxury vehicles.
Where are H tires on a car?
You will spot tires with H on the sidewall on sedans, SUVs, and crossover SUVs. Such vehicles have a high horsepower, which translates to more speed. You will also see them on luxury vehicles. According to automobile pundits, H tires are on the lower end of sports cars.
Are H rated tires safe?
Opting for H-rated tires is fine – provided that you keep to the 130-mph top speed limit instead of the 149-mph limit supported by a V-rated tire. To add, make sure to use the same speed rating on all fours for best performance. As a precaution, never opt for tires with a speed rating two tiers lower than the original requirement for your vehicle.
Do I need 4 tires or 2?
