i drive aggressive half and easy the other half
what tread wear rating do i need to get 20000 miles

 

I get about 20k from a set of Eagle F1s, they're 300 treadwear. Your mileage may vary.

I would get 20k from a set if I rotated them, and didn't go on the track. I'd change the fronts about every 10k-12k and the rears have hardly worn. A track day will knock a 1000 or 2 off that.

 

One way to gauge is what tires have you had in the past and on what car and what amount of mileage did you get out of them for their given treadwear rating.

Every person is different and every car and situation is different.

If you are driving in the same way on the same roads using a sporty compact car during the same time of year then the mileage tendency and treadwear will carry over. The more you load in your car the more the tires can wear. The better you keep tire pressure up and rotate the better the wear.

20,000 miles is about 300 to 340 treadwear but the exact number will vary with each tire and manufacturer. A tire with about 200 treadwear is going to last about 66% as long or about 12-14K miles for most of us.

Realize that just because there is a little tread left, the tire may not be very safe in the wet or as good for performance. Old rubber gets noisy and hard and while it tends to wear slower it's a shadow of what a new tire is capable of. 4/32" is about ready to change if you are in wet areas and need good grip. Otherwise drive slower.

Get an alignment with every set of new tires, or about every 2 years or sooner. Set the specs to stock and you should be fine. Mis-alignment is bad on tire wear. The more performance driving you do on tires that are not soft will wear the tires much more. If you plan to do performance driving school or track events then a Max Summer or Ultra High Perf Summer tire makes more sense. If street driving with some enthusiasm is more your speed then a Ultra High Perf All Season tire might work better.
