Introduction and Wheels for 2004 C4S Winter Tires

[AgeRebel]

I've recently taken delivery of a 2004 C4S. This would be my fourth Porsche having previously owned a 930 Turbo, 964 C4 and 993 C2 over the years in succession! This forum has been extremely valuable from my purchase considerations all the way to resolving a few issues and became a Contributing Member. Having been on many other forums, this is by far the most knowledgeable and supportive community. It made my decision to get another Porsche that much easier! I've never had to post until now as it was almost certain to find the answers using the search feature, and I've been looking forward to this opportunity to introduce myself.

I am planning to go with the Porsche N-spec and dealer recommended Pirelli Winter 240 SnowSport 225/40R18 fronts and 265/35R18 rears. The user manual recommends that the rears are mounted on 10J x 18 but the stock wheels are 11J x 18 (fronts are same for summer/winter so that's good). According to my dealer, the 265/35R18s will fit and work fine with the 11J x 18 but "will look a bit odd" because the tire contact tread width will be noticeably narrower than wheel rims.

Can anyone share any experiences or shed some light with 265/35R18s on the 11J x 18? Or is it necessary for safety and/or performance to get a pair of 10J x 18 rears just for winter use?

Hi,

I got the Yokohama Advan S4 275/35/18 which fit on the stock 11Jx18. These are all season Z rated and have a very good rating.

Hope it helps.
