Whenever you want to switch tires for your vehicle, you must understand how to read tire size to select the best. Fortunately, knowing the exact tire size is simple, and you can get all the information you need in your owner’s manual. Also, physical measurements such as width and diameter are helpful too.
If you can’t locate your vehicle’s owner’s manual, you can also find a tire fit guide around your gas tank hatch, the driver’s side door jamb, and inside your glove box door. You can also get information about your tire size on the sidewall of your current tires. Common tire sizes include;
- 14-inch diameter tires

Understanding Tire Sizes
Understanding the sizes of tires can be confusing and challenging. To check for your tire size, you’ll find some numbers on the sidewall listed in millimeters while others are in inches. When buying a new tire, you should select a tire for your car based on how and where you drive. You’ll find the standard tire size in the user manual.
If you want to switch to another tire, check the numbers on your existing tire to determine which tire to purchase. The numbers and indicators on the sidewall of your tire are passing information. What do they mean?
1. Tire Type
The first letter indicates the class of tire. P stands for passenger vehicle tire. LT stands for light truck tires designed for vehicles and cars carrying heavy loads on rough terrain. ST stands for Special Trailer. These tires are for all kinds of trailers, including the fifth wheel and utility trailers.
Note that if you can’t find a letter before the first digit, it’s a metric tire that people call European size. You will also find the European size tires in millimeters, but their load capacity differs from those of P or LT tires.
2. Tire Width
The three-digit number you will find after the letter gives information about the tire’s width in millimeters. You can also call it the section width.
3. Aspect Ratio
Aspect ratio indicates how tall or high the tire’s sidewall is. You will find the two-digit aspect ratio after the forward-slash from the width number. The aspect ratio is always in percentage on the sidewall.
4. Construction Type
R is for radial tires, which is the standard for most tires till today. They are unique and popular because they have better rolling resistance that ensures better gas mileage and excellent road grip and offers comfortable rides and durability (more so if you know how to get better gas mileage).
5. Wheel Diameter
The two-digit indicates wheel diameter in inches. It’s the distance between the two places where you seal the tire to the wheel.
6. Load Index
It can be two or three-digit, indicating the tire load index. The load index symbol describes how much load a tire can carry.
7. Speed Rating
The last letter on the tire indicates the tire speed rating. This shows the speed it can travel for a particular time. A tire that has a high-speed rating will handle heat well and provide more speed control. A tire with a speed rating “S” can provide up to 112mph, while a tire with the rating “R” will provide up to 106mph.
You need to note that this is not the required cruising speed but the maximum speed that the tire can produce. Below are the most common letters that indicate speed rating and the top speed they provide.
- Q – 99mph
- R – 106mph
- S – 112mph
- T – 118mph
- U – 124mph
- H – 130mph
- V – 149mph
- W – 168mph
- Y – 186mph
- ZR – 186+ mph
8. Rim Diameter
If you select a tire with the P225/70R16 91S, the best rim for it will be a 16-inch diameter rim. Whenever you want to change your rim size, you will also have to change your tire size. Using a tire made for a 16-inch wheel diameter on a 20-inch rim may be harmful to your vehicle.
Compare Tire Sizes
Installing the right tire for your truck or SUV goes a long way in affecting the overall performance of your vehicle. Before you switch tires, you can use online tire size calculators to choose the exact size for your car. You don’t need to be a tire guru to use these calculations; you just need to know how to interpret the information.
Once you enter a tire size on the calculator, it displays some information, such as
- Tire section width
- Rim width range
- Overall diameter
- Revolutions per mile
- Speedometer differences
LT Tires Meaning: #1. Tire Section Width
The tire’s width is essential for preventing all sorts of clearance issues. A big tire can scratch or crack the wheel or suspension component, especially when you turn the wheels. Also, a big tire can lower gas mileage.
LT Tires Meaning: #2. Rim Width Range
Note that any tire you choose can only fit on wheels within a particular range. A big, wide, or too narrow tire each has a specific wheel, and if it’s too big or too small for the wheel, it may result in tire failure.
LT Tires Meaning: #3. Overall Diameter
You need to know the overall diameter of your car tire because different heights rotate and function at different speeds. The overall diameter can affect the speedometer, odometer, ABS, etc. Ensure the overall diameter of the tire you choose is within 3% of the height of the original stock tires.
LT Tires Meaning: #4. Revolution Per Mile
A tall tire will cover more distance as the wheel rotates because it has a large circumference. Also, a taller tire will have a lower rotation per mile, while a shorter tire will have a higher rotation per mile. You can use the revolution per mile to calculate several vehicle parts, such as the speedometer and odometer.
LT Tires Meaning: #5. Speedometer Difference
If you just recently changed your car tire and the height is different from that of your stock tire, It will cause your speedometer and odometer to be inaccurate. Your speedometer will read slower with a tall tire, and the speedometer will read faster with a short tire. Comparing tire sizes will make you select the right one for your car or truck using all these diameters.
LT tires can handle heavy loads, and they are the best sets of tires for SUVs, trucks, and vans. They are the best tires for cargo hauling. All LT tires are made of a rubber compound that can resist wear and tear for a very long time. This contributes to their durability and toughness.
LT tires are also hydroplaning resistant, and they reduce driving difficulties mainly because of the unique tread pattern they contain. LT tires differ in construction if you want to compare them to any kind of tire because of the materials that go into their production. They offer higher loading and carrying capacities and are the best for heavy trucks and vehicles that carry heavy loads on and off-road.
LT tires are expensive, and this is because of their durability, weight, and technological features used in their production.
LT On Tires Mean
People mostly take It as a tire rating instead of a category of tires. LT on a tire means light truck, which means that these tires are specifically for trucks and SUVs. You will mostly find the label LT in front of your tire size.
Metric To Standard Tire Conversion
Knowing the metric tire conversion can be very difficult. For instance, on inch tire sizes, the first number gives information about the height while the second indicates the width. However, with metric tire sizes, the first number indicates the width while the second number indicates the sidewall height.
Adding the sidewalls and the rim diameter will give you the correct tire height. You can use a calculator to find the metric tire conversion or browse tires online by choosing the one you want from different options.

- The letters “LT” on a tire signify that it is a “Light Truck-metric” size designed for heavy loads and towing.
- An “LT” tire size that ends with a letter “P” means it’s a “Flotation Light Truck” tire designed for off-road use.
- LT tires are built differently from passenger tires, with beefed-up internal belts and cords to support extra weight and heat.
- LT tires have squared-off shoulders and a more aggressive tread pattern, which can generate more road noise and affect fuel mileage.
- Whether you need LT tires depends on your vehicle’s weight and usage; they are ideal for heavy-duty trucks and SUVs used for towing and carrying cargo.
- LT tires do not increase the overall load capacity of a vehicle, which is determined by the manufacturer’s specifications.
- It’s important to check the sticker in your driver’s door jam or owner’s manual for maximum weight and load ratings and original tire sizing and classification.
- There is no mileage warranty for LT tires because heavy-duty use makes wear unpredictable, and they may wear quicker than passenger tires.
