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

hi all, just wondering, am i ok to go from 285/30x18 to 295/30x18?? not sure if it will affect anything or upset the handling? due to change tyres soon! cheers Simon

POST 2Original post

Likely to induce more understeer.

POST 3 / ORIGINAL POSTEROriginal post

would going to 235 on the front counter that? apart from poss increase in understeer are there no issues regards clearance (i know its only a small increase in width but just unsure)

POST 4Original post

Hard to say. Surely, especially on such a new car, it's best to stick with the recommended 'N' rated tyre sizes. As you increase the width you normally have to reduce the profile to maintain the same rolling diameter. Porsche might claim that this could jeopardise the rotational caliibrations for the ABS, PSM etc Pirelli P-Zero Rossos are supposed to be very good for road use on the 996.

POST 5Original post

I have the Porsche TSB on tyre specs. If you would like a copy send me an email and I'll attach it to a reply. I have the PZero Rossos which have lots of grip, but are a bit noisy. I will try the Conti Sport Contacts next time.

POST 6Original post

Richard I have the Conti's on mine with 285s on the rear. They seem fine. Just had to replace an almost new one having put a nail through it from my garage floor. A bit peeved and relieved of £184. Fortunately no passenger on board, so punctured wheel travelled round with its seat belt on. Hugh
