I searched and couldn't find one, so I'll try to start one. This will be the tire treadlife thread. Please post your tires, size, brand, etc. Post your alignment specs, how many miles you were able to get out of a set of tires, and your driving style/habits that may lower the treadlife of a tire.

I'm at work, my alignment specs are at home, so please post away.

Michelin PS2's 275/35/19, 245/35/19.
About 15k miles on them today and still have about 7-8mm of tread.
The car was not lowered until recently.
I rarely spin my tires, but do so occasionally, I take turns fairly fast, and I accelerate pretty hard when I can.

 

A professional tread depth gauge doesn't read about, it has a decimal point in the mm scale.

PS2 is the finest street tire made in the world and is priced accordingly.
For those who will only accept the BEST.

 

Stock RE050A's: 18,564 miles
Manual 06 coupe, no drop. Working them over pretty hard, but never peeling out. had about 2000 left in them, but i was read for new ones...

 

Unforutunately, I didnt use a professional treadwear depth thingy. I only have a ruler =X
