How to Interpret Car Tire Ratings

Tires are an important part of any vehicle.  This is why you will want to learn how to read the tire ratings.  By understanding what they mean and knowing what specs to use, you will be able to fit your vehicle with the perfect tires.

• Understand what a car tire ratings placard is so that you don’t get ripped off.  This is found on the driver’s side door, in the glove box or on the trunk.  Here you will find out if these tires are the right size, inflation and load limit for your vehicle.


• Traction grades will tell you how well the tire can stop on wet pavement.  These ratings range from highest to lowest – AA, A, B and C.  A higher graded tire will stop quicker on wet roads.


• Treadwear grades tell you how a tire will wear.  The higher the number is, the longer it will take for the tire to wear out. 


• Temperature grades indicate how well a tire is able to resist heat.  These include (from highest to lowest): A, B and C.  This information is especially important whenever you are driving a long distance in hot weather, as you will want a tire that can resist blowouts and tread separation.


• Take a look at the load index.  This will tell you how much weight your car will be able to carry while it has these tires on.  You will find that this information is especially important if you plan to be towing anything.
