Understanding Tire Sizes
Tire sizes are typically expressed in a combination of letters and numbers, which can be confusing for those who are unfamiliar with the terminology. However, by breaking down the different components of a tire size, you can gain a better understanding of what each part represents. A typical tire size is expressed as follows: P 225 60 R 16 95 H. Let’s take a closer look at each component:
Tire Size Components
P – This letter represents the tire type, with P standing for passenger tire. Other common tire types include LT for light truck, ST for special trailer, and LT-M/T for light truck mud terrain.
225 – This number represents the tire’s width in millimeters, measured from one sidewall to the other.
60 – This number represents the tire’s aspect ratio, which is the ratio of the tire’s height to its width. In this case, the tire is 60% as tall as it is wide.
R – This letter represents the tire’s construction type, with R standing for radial tire. Other common construction types include LR for load range and SL for special load.
16 – This number represents the tire’s rim diameter in inches.
95 – This number represents the tire’s load index, which indicates the maximum weight the tire is designed to carry.
H – This letter represents the tire’s speed rating, with H standing for high-speed rating. Other common speed ratings include Q for high-speed rating, V for very high-speed rating, and W for extreme high-speed rating. (See Also: Where to Buy Blemished Tires? Affordable Options Online)
How to Read Tire Labels
Tire labels provide a wealth of information about your tire, including its size, load capacity, and speed rating. By understanding how to read tire labels, you can make informed decisions about your vehicle’s maintenance and performance. Here are some key things to look for when reading a tire label:
Tire Label Components
Tire Size – The tire size is typically listed in a combination of letters and numbers, as described above.
Load Capacity – The load capacity is listed in pounds and indicates the maximum weight the tire is designed to carry.
Speed Rating – The speed rating is listed as a letter, with H standing for high-speed rating and V standing for very high-speed rating.
Tread Depth – The tread depth is listed in inches and indicates the depth of the tire’s tread.
Tire Pressure – The recommended tire pressure is listed in pounds per square inch (PSI) and indicates the optimal pressure for the tire.
UTQG Rating – The UTQG (Uniform Tire Quality Grade) rating is a measure of the tire’s tread wear, traction, and temperature resistance.

- Tire size
- Load capacity
- Speed rating
- Tread depth
- Tire pressure
Step 3: Verify the Tire Size
Once you have located the tire information placard and checked the tire sidewall, verify the tire size by comparing it to the information on the placard. Make sure the tire size, load capacity, and speed rating match.
Common Tire Size Mistakes
When it comes to tire sizes, there are several common mistakes to avoid. Here are some key things to keep in mind:
Tire Size Mismatch
A tire size mismatch can occur when a tire is replaced with a different size than the original equipment tire. This can lead to a range of problems, including reduced fuel efficiency, uneven tire wear, and increased risk of tire failure.
Incorrect Load Capacity
An incorrect load capacity can occur when a tire is overloaded, leading to reduced tire life and increased risk of tire failure. Make sure to check the load capacity of your tire to ensure it can handle the weight of your vehicle.
Incorrect Speed Rating
An incorrect speed rating can occur when a tire is driven at speeds above its rated limit. This can lead to reduced tire life and increased risk of tire failure. Make sure to check the speed rating of your tire to ensure it can handle the speed of your vehicle.
