What tyre sizes can I run on my 997.2 cup?

The car has come with:

Dunlop
Front 245 650 18
Rear 305 680 18

Pirelli
Front 265 645 18
Rear 315 680 18

Can I fit Michelin
Front 27 65 18
Rear 31 71 18
or are these too big?

Any advice would be much appreciated

I have a 997.2 cup and run Pirelli P Zeros
Front: 275/645-18
Rear: 315/680-18

Thanks. Good to know that the 275 fit. I thought they might have been too wide. I guess that means the Michelin 27/65-18 will also fit the front??

I don't know for sure about the Michelins. I do know that some 997.2 cup owners run 265's on the front.

I have a 997.1 with most of a 997.2 conversion done.... a little bit of messaging and easily running a 285/645 front and 315/680 rear. I could probably get a 295 or 305 up front with a bit more work, and the rear would easily fit a 325/680 as it sit (still have stock narrow body rear 1/4 panels on, just trimmed and rolled a tiny bit). I think to run the 710 rear the inner wheel well would need to be changed to the Grand-Am style.
My example is all based of the Pirelli P-Zero's. Otherwise my car is on 'stock' cup suspension specs... no fancy R/RSR bits just yet.

Michelin's seem to be some of the smaller tires, Pirelli in the middle and the Yokohama the largest, going off the "sizes".

Thanks THJR. It would be interesting to know if any 997.2 owners have tried the 31/71's on the rear without any modifications...

Digging up this old thread: Anybody successfully fitted a

Michelin Cup N2 27/65 and 31/71

to their 997.2 GT3 Cup ?

Thanks

Anyone fit a Michelin Cup N2 27/65 and 30/68 to their 997.2 GT3 Cup?

I run 275-35-18's front & 335-30-18 rear (Hoosiers)
on OZ 10 & 12 inxh centerlocks.
Perfect fitment.

Q&A

Thanks but it's about the height of the rears that is the challenge
Cup cars have higher tires then street cars

Are they not the standard size for Michelins on a 997.2 Cup?

Yannick-HST

Standard was 25/64-18 and 30/68-18.

I don't have a 997.2, but I have run both mich 27/65 and pirelli 275/645 on the front of my 996R and the 275 pirelli is larger than the 27 mich.

Will 31 71 18 Michelins fit on the rear of a 997.2 Cup or are they too big?
