SMF tires - Toyota Yaris Forums

Hmm, it looks as though I may have painted myself into a corner with these rims. I had bought them with the intention of mounting R1R 195's--they're only 15x5.5--so anything wider than a 205 is asking for trouble. I'm also somewhat limited by budget (hence the used wheels) and looking at the available R-comps makes me a bit light headed.

As far as "not standing a chance" I don't intend to win. I just run for fun on the local level.

I've been told the 195 R1Rs would be really slow on any rim narrower than 7". If it were my money I'd grab a set of Dunlop Z2s they have a super stiff sidewall that should handle the narrow rim better than the soft side walled Toyo.

Is there any real difference between the Z1 Star Spec and the ZII? The marketing hype seems almost identical, and they both feature rigid sidewalls.

I never ran the z1s but I've been told by some extremely reputable sources that the 15" z1s don't compare to the z2s.

I can tell you I really like the z2s while they might not be the best track day tire, they wear better than anything I've used so far which is saying something. I've run Autox on them and found them to be about .5s slower than proper r1r but I completely hate the r1r so if I wasn't trying to "win" I'd run the Dunlop or some other stiff side walled tire on a narrow rim.

If you want fast and durable go with the 205-50-15 BFG R1-S. If you start to get serious then you need to look for a 13x9 wheels and get into a set of 255-40-13 Hoosier A6.

I ran 205/50R15 DZ101s last summer and was pretty happy with them all around. There's lots of other things that I would like to do for the cost of R-comps and 13" wheels first, i.e. my gearbox build, since I can enjoy that on a daily basis instead of twice a month in the summer. =)

By the title I thought you were looking for SMF class tires, not street tires.
