Do you know what those 3 numbers on your tire mean? Seems complicated.
Trust me when I tell you that neither did I when I started working in the world of used car dealerships in Colorado. If you have ever shopped for used tires at any store or online you will see that they are asking for those 3 magic numbers.. Make sure you learn these 3 numbers because these numbers can dramatically effect the performance of your tires.
Just because your car or truck came with 4 new or used tires does not mean that you can’t switch them up. There are lots of things that you can do with your tires to increase the performance of your car.
The 1st number is the width of the tire in millimeters when its fully mounted on the rim but BEFORE you put it on your used car or truck. The higher the number the more surface traction the tire is getting making it turn better on corners. You will see Nascar Drivers and Drag Racers have very wide tires. If you are looking to save on gas and have very little resistance, you would want to have a smaller number. Makes Sense?
The 2nd number is much more confusing, and is actually a ratio for the tire. More of a math question. To everyone except a tire technician, the bigger the number, the better MPG’s and comfortable your ride will be. The Smaller the number, the more sportier ride but may be a little rough. So stay big! Usually you will see between 40-60 on cars.
The 3rd and last number is the radius of the tire in inches. So if you see R15 (Like in Picture above) It means that your tire is for a 15 inch rim. Generally, the smaller the rim the better miles per gallon you will get but you get worse handling so there is a tradeoff with both of them.
Hope this helps!
