If you are trying to make a decision between competing sets of quality tires here is a good way to make the final cut.

Depending on if you are doing somehting like autocrossing or just a lot of highway driving, you will probally want to decide if you want a sticky or hard tire.

The easiest way to tell how soft or hard a tire is is by looking at its UTQG number (which is sometimes referred to as the treadwear rating). This number is a factor that indicates how long it takes a tire to wear out. The lower the number the softer and stickier the tire but the tire will wear out faster. The higher the number the harder the tire is and therefore there is less grip but the tire lasts longer.

A good pair of racing tires can have a UTQG rating lower than 50 and a high mileage family wagon tire can have a UTQG rating like 400 or more.

Of course there are other important conciderations like tread patterns and tire stiffness and construction to concider, but those things aside the UTQG rating is your best general indicator of rubber stickyness.

I hope this info proves useful to your search.
