Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

I ran 245/35s up front without any rubbing but it depends on your camber as well - I had about -1.5degrees of camber which is considerably more than stock.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I am looking at the RH Cup wheels for my 996 C2. But they have 18x8.5 and 18x10. WOuld a 10 fit the front? I doubt it but what widths can I fit on it? Thanks

POST 2Original post

I have my Kinesis Supercups for sale if interested?! Not sure a 10" wide wheel would fit on the front and honestly, I'm not sure why you would want that. 8.5" is more than wide enough IMO.

POST 3Original post

I use 18x9 and 18x11 on my 99c2 race car. Anything bigger would get pretty tight. For a street car I would stay with the 8.5 in front. Jim

POST 4Original post

What tire are you going to use on a 10" wheel in front? To take full benefits from a 10" wheel, you'd need to use at least a 265 tire. A tire that size in front will create some serious hunting over uneven pavement. I'd stick with a maximum of 9" and 11" sizes as per Jim's suggestion above. Better yet, how about the GT3 sizes?

POST 5Original post

I'll third the vote for a max of 9 but 8.5 is safer. I had 8.5s on the front of my 99 996 and they could have been 9" with the right offsets. Any bigger than that would have stuck out of the fender. I ran 245/35s up front without any rubbing but it depends on your camber as well - I had about -1.5degrees of camber which is considerably more than stock.

POST 6Original post

Viken is right. I ran 265s in front for awhile when it was the only size Michelin Pilot Sport Cup that would work. You don't want to try that on the street.

POST 7 / ORIGINAL POSTEROriginal post

Thanks for the input guys. Looks like I will stay with the 8.5 with 235's up front. Great advise, as always
