[s-cars] Question on tire tread depth tolerance..

[Taka Mizutani]

Nah, only two at a time, although I would not run different brands and
models of tires on the same
car- that could make the handling unusual.

Good excuse to justify getting a new set of tires.

Maybe I'd do all 4 if the difference was really large- brand new 10/32 vs.
worn-out 3/32 or something like that.
Even still, if you do the math, I don't think the difference in rolling
diameter is that much.

If you're storing the car in the winter, why not get something like Falken
Azenis RT-615? I'd say that if you're
going to spend some serious cash (such as Michelin type cash), then the best
performance tire to get
currently is the Yokohama Advan Neova AD-07. The Falken and the Hankook RS-2
Z212 are the other alternatives-
both tested better than the Kumho Ecsta MX.
