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've read several threads on here and think I now have a good handle on wheel offsets. I currently have 16" wheels on my '99 Boxster with offsets of 50 (6") front wheels and 40 (7") on rear. I found a set of 17" wheels with offsets of 55 (7") on front wheels and also 55 (9") on rear. Based on my research, I don't see any fittment issues with these 17" wheels on my Boxster. Anyone care to confirm or disagree? Tires will be 205/50/ZR17 and 255/40/Zr17. Thanks for any input! Kevin

POST 4 / ORIGINAL POSTEROriginal post

Starting to 2nd guess myself on the 17" wheels that I just purchased. Worried about the offset on my rear wheels......9" rears with a 55 offset. The chart above seems to indicate an offset of 48 for the rear wheels on the '99 Boxster.....would mounting a wheel with a 55 offset require a 7mm spacer? Can I mount these rear wheels without needing a spacer? Any help VERY appreciated!
