Best Tire Size For Auto-X

[Auto-X-ZTS]

The 215/40-17 (Z1 StarSpec) is a great choice for the SVT. Its a little shorter and will help the gearing...and fits nice on a 7" wheel. It also has a stiffer sidewall than most of the other Uber Street Tires--and that helps a FWD car like the Focus (read; nose-heavy)as well.

Not on an SVT--unless you get some hard-to-find wheels; also, a 205 is really too narrow to be effective on a 2700 pound car. The 215 is too, but they tend to run closer to a 225 than a 205. The 225s, especially on the SVT, are all kind of tall and the last thing that car needs is more gear...it already goes plenty fast in 2nd. A 225/40-17 would be a good choice too, but is not made in an Uber Street Tire tire. A 235/35-17 R1R would be an interesting choice, if some wider wheels were used. A 225/45-16 R1R would also be an interesting choice...
