These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

6 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

hi everyone. i'm sure this has been answered somewhere on this site but I can't seem to find it using the search engine. the search engine won't allow me to search for "18" because it's less than 3 letters. I was wondering if 235/40/18 and 265/30=5/18 are ok for a 99 996 with factory 18x7.5 and 18x10 wheels. Thanks a bunch!!! I know that 225 and 285 are better but I can't seem to find any good deals on those. I found these tires available right now and want to know if they'll fit.

POST 2Original post

Look under 'Bigger Tires' I had some questions when I changed my tires. By the way where are you looking for the tires, and how much are you looking to spend?

POST 3Original post

What I suggest you do is go to Tire Rack, then check out the tire. Usually, under the tab for "specs" for a particular brand, they will list the recommended wheel widths for the various tire sizes.

POST 4Original post

But a 235/40/18 may be a bit wide for a 7.5" rim width. Are you sure your don't have 8x18 rims in the front?

POST 5Original post

It is and with no benefits too. He doesn't if his wheels were factory installed on the '99. They used 7.5" fronts before MY 2002.

POST 6Original post

Also check out www.wheelenhancement.com. I got my Pirellis from them, and t notch. Specialize in Porsches so they will probably be able to answer your questions. There prices were better than tire racks, and I love my current 285's. Way better than my previous 265's
