sequential tire sizes

225 75 R15 Stock
235 75 R15 then whats the next size up 30?


1.5 lift all four corners where should I stop?

I ran 275/65R15's on mine with NO lift. The tire was quite a bit wider, but nearly the same height as the stock ones. As it stands my 97 has a 2.5-3" lift and I clear 31x10.5 with very minimal rubbing.

I found http://www.miata.net/garage/tirecalc.html to be helpful in deciding tire sizes on my projects around the garage.

Rule of thumb is usually 2-3" lift 30x10.5 safe, 3" lift plus can do 31x10.5 (correct me if wrong) and so forth. With a 1.5 lift I would not go any more than a 30x9.5 type size tire without problems rubbing.

Hope that helps some.

I'm in the process of doing a 1.5 inch lift. Personally I wouldn't go bigger than 235's with that amount of lift because I think I'd lose wheel travel going larger.

For 9 months i drove my allstock cherokee with 30x9.5s and they barly rubbed and only at full flex.

I'm running stock suspension, 3.73s and 30x9.5s
Lacks guts in overdrive, especially at altitude, but it stuffs well and at 80 MPH the motor turns 2650 or so.
At sea level, you could pull 30s with stock gears probably not a big deal. At altitude in Utah... it sucks.
