I was given a set of wagon wheels and want to put a good set of street/track tires I was looking at the nitto nt05.

the rims are 17x8.5/18x9.5
i was looking at these nitto sizes
275/40/17 (they dont make an oem size this is .02 inches smaller in overall diameter)
275/40/18 (which is the same size as oem)
will the active handling system pitch a fit on the fact that the front is the same width as the rear?
or should i step up to a 295/35/18 which is roughly .54 inches smaller in overall diameter but wider in the rear.

They will be used for autox and hpde events nothing very serious just a beginner looking for a nice set of weekend tires.

Thanks in Advance!

The computer will have no problem with those diameters - front & rear. The computer doesn't care about the widths.

However, I'm a little concerned about putting a 275 tire on a wheel that is only 8.5" wide.

thanks for the info on the computer not caring about the width.

as far as a 275 on a 8.5 rim, i have the same feeling as well, my past experiences with nitto tires have been that they run a little narrower than indicated so im hoping its the same case with the 275, if not then ill probably look at some other company's offerings

I ran Kuhmo XSs in 275/35-18 on OEM 8.5 rims for AutoX (as well as on the street) with good results. You should be fine.

I'm driving a C6 - 285s on the back. You may experience some oversteer but that should be managable playing with pressures and your driving.
