Default cup tires up front on stock z06 wheels??

what's up guys im looking into getting Michelin cup tires for my z but I saw that the closest size for the front is a 285/30/18 and I believe our stock size is 275/35/18 what are my options without changing wheels? the rears there is no issue I was planning on running the 345/30/19. If I cant use them then so be it, just wanted to double check before I ordered them!


thank you

Lou

285s will be fine up front. You would want that offset anyway. 345s/285s

The 285's are fine. I run them on my track wheels. MPSC ZP's-19/20's on my 2011 Carbon edition Z06.

The problem with that 285/30-18 cup tire is the diameter...its considerably shorter than the stock size that is called for on our Zs. And running the taller 345/30-19 tire on the rear is bound to throw AH/TC issues. You'd be better off running the 325/30-19 N-spec cups on the rear.

Hey Ron,
What size and type cups tires came on your carbon, and what style was the OEM rim??

the only reason i was getting cups was because i was getting the rears for a killer deal, do you think i should just hold off and get the PSS tires in the 275/35/18 and the 345/30-19 in the rear. i run this set up now with run flats up front and 345 NTO5Rs in the rear with no issues, if i run the 285 up front and the 345 in the rear it'll cause some problems?

I run this same setup with no problems, except picking up every little pebble on the street once the tires heat up
