Which RA-1's for 17" Rims?

I have the standard 17X7 Front
and 17X8 Rear rims.

Suggested tire size are 215/45-17 Front & 245/40-17 Rear

The problem is Toyo Ra-1's only come in these sizes:

--------------------Rim Size-----Diameter-----Width-----Rev's per mile.
235/45ZR17-----7.5-8.0-9.0-----25.4----------9.3-------------834
205/40ZR17-----7.0-7.5-8.0-----23.4----------8.5-------------887
235/40ZR17-----8.0-8.5-9.5-----24.4----------9.6-------------852
255/40ZR17-----8.5-9.0-10.0----25.1---------10.2------------828
275/40ZR17-----9.0-9.5-11.0----25.67--------10.9------------812
205/50R17-------5.5-6.5-7.5-----25.2---------8.31-------------823

Any Suggestions?

Thanks!

235/45 fronts.
255/40 rears.

Would seem to be the logical choice.

I take it you have '04 OEM rims?

I have run 235/40 front 275/40 rear on the Volk CE28Ns with great success and just a little rubbing. My recommendation above for you reflects your narrower rim width and an uncertain tho likely good wheel offset.

With 235F/255R, you might need a stiffer front bar, but not sure as 225F/255R is still fairly balanced. Dave, you didn't have any problems with the shorter 235/40 front and the taller 275/40 rear (assuming this was when you had stock ABS)? I currently use 235/45F with 275/40R to keep the diameters close.

davepk

nope, the ABS never did balk at the different tire diameters like i thought it might.

. I should have tried that too then because the 235/40's are .3 inch wider and also lighter than the 235/45's. Just raise the front suspension to maintain current rake.

Ok, but my front rims are 7.0" and the rears are 8.0", do you think that would be a prob Dave or Richard?

Thanks Again.

My guess is your rims would be too narrow, but I've read that the auto-x'ers run 245-275 on those rims (but are they faster?)
