All car tires might look the same to an untrained eye. However, car tires come in a variety of sizes. Sometimes, you might even replace the old tires with new ones that are different from the others.
Overall, it can be confusing to find out the right kind of tire for your car. Hence, we have compiled some information about tires that will help you.
Identifying the Right Tire Size
Tire size and its characteristics can be identified by reading the numbers and letters mentioned on the sidewalls of the tires. Here’s how you can learn it.
- Tire type
This is the first letter mentioned on the left side of the sequence. The letters you are likely to see are “P”, “LT”, “T” or “ST”.
- “P” – passenger vehicle
- “LT” – light truck
- “T” – temporary spares
- “ST” – special trailer
- Tire width
This reading follows the type of tire. You will find a number next to the letter or vice versa for example “P225” or “225P”. This means it is a passenger tire with a width of 225 mm.
- Aspect ratio
After this, you will come across a number, maybe say 65. This is the aspect ratio of the tire or the height of the tire from the center of the rim to the tread. Aspect ratios are in percentage but you’ll not find a % mark after the number.
- Construction
This is denoted by letters like “R”, “D” or “B”. construction means the type of internal build-up that is responsible for the tire’s stability.
- Rim diameter
As the name suggests, it is the diameter of the rim in inches. You can find a number after the construction letter.
- Load index
It shows the amount of load a tire can bear. You will find a number anywhere between 1 to 150.
- Speed rating
This is denoted by a letter, for example, “R” or “S”. this shows the speed limit on which you can run the tire.
In the end, it can be summed up as P225/60R15 95R. If you can interpret this, you know all about tires.
