Talking UNDERsized Tires Question

I have a set of Michelin Pilot Alpins from my 16' C2S that I recently sold.

Question is - would 245/35/R20 (front) and 295/30R20 (rear) fit the TTS wheels?

From what I understand, they are 305 in the back, which I believe would be a problem. I would think oversized tires would be ok but undersized...maybe not so OK.

They only have a little over 2000 miles on them...if I can't use them, I will sell them.

Thanks guys

The specs on the individual tires from the manufacturer give the allowed width for the rim.

Looks like the P4 isn't available in 295 on tirerack, but the 285 can go on a 10.5" wheel. That would not fit your 11" rear wheels.

Need to track down your specific tire model and then this data.

They will fit no problem . But I would go down to 235 fr if your running 295 rear on a 4 wheeled dr TTS. Fr/rear ration must be kept close.

Copy that, thanks a lot for the quick response guys. I may end up selling the tires here on rennlist instead.

295 will fit an 11" wheel. No problem there. However, aren't TTS rears 11.5"? That may be a stretch - literally.

However, as Karl alludes to, the ratio of the front to rear circumference must be within few percent of the stock size or one or more of the ECUs will complain. You'd need to do the math and see.
