and what gnegroni said is also one of the most important things- tread ratings don't really mean that much per se. just know that if it's low, it's going to wear fast and if its high, it's going to wear slowly, but there's no definite mileage. especially when everybody drives differently and under different conditions- i.e. highway vs in town.
and as everybody's been saying...there's no such thing as good tire rating and good grip.
Thanks for the backup, Eye8Pussies. My trustworthy tire salesman keeps reminding me that those treadwear mileage stated never really come close to manufactures rating.
Back to topic, do keep in mind that if a tire states traction AA > A, but not exactly as you might think:
"
Traction grades represent the tire's ability to stop on wet pavement as measured under controlled conditions on asphalt and concrete test surfaces. As of 1997, the traction grades from highest to lowest are "AA","A","B" and "C".
A tire graded "AA" may have relatively better traction performance than a tire graded lower, based on straight-ahead braking tests. The grades do not take into consideration the cornering or turning performance of a tire."

"Traction: Tire traction is rated AA, A, B or C, with AA at the top of the scale. This rating is based on the tire's ability to stop a car on wet concrete and asphalt.
It does not indicate the tire's cornering ability. According to this NHTSA page, the Firestone Wilderness AT and Radial ATX II tires that have been in the news have a traction rating of B."

Not all is that bad...having AA vs A where it rains most of the time like my homeland is a definite plus.
In the end, best for traction might be wider size tire & rim (going from 6.5" to 7" or 7.5" - bigger contact patch (more suspension strain though which translates to having worn-out bushings ahead of time). I've also read that the best performing tire is one that is not much wider than the rim (better tire structural stability). Not sure if using spacers adds to traction (spreading out wheel stance).
LOL I do have a question though, what is the correct way to spell it: tire or tyre?
