I am looking at nankin AR1.

Front is 265/35/20
Rear is 325/30/21

can I run these??

has anyone done this?

Yes you can. I know folks that run these as track tires and absolutely love them.

Angryinch

Awesome. I was concerned the rolling diameter might be too far out from front to back?

I am hoping these are better than cup2s, which just require a ton of heat to get soft. (Not so much road course, more into drag racing)

I have them ordered, here on Friday. I will post impressions vs Cups2.

Cheers

I run the 991.2 GT2/3 N2 spec PSC2 on my 992 TT for both street and track in those exact same sizes. The front-to-rear rolling diameter ratio is practically the same as stock (less than 0.2% difference, well within tire wear tolerances), so no issues here.

Ahh perfect! I must have did my math wrong. I was getting a 5 percent difference. I’ll double check it, thanks!
