Suggestion
Most run 17s for AX/DE/TT because the tire size/width is just right for the 986 car balance and there are a ton of good tire choices available.

I run 18s on my 987.2 and they do allow a bit wider tire but they cost 30% more.

I think people use 17s to go with a square setup of 255s but that may also require swaybar changes to keep understeer in check.

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

For autocross events, has anyone played with different rim sizes? I run 18" on the street, but was curious on others opinions. For autocross events, is there any big differnce between a 16,17 or 18" rim assuming the same diameter tire? I know that lower profile on a 18" would be tighter, but then the 16" with a 55 might give better roll. Thoughts?

POST 2Original post

Rim size will govern a bit of what width wheel/tires you're trying to use. I think people use 17s to go with a square setup of 255s but that may also require swaybar changes to keep understeer in check. A square setup has the ability to rotate all 4 evenly. Also, not all tires are available in all rim size and width combinations. I looked into this over the winter to possibly make some changes. I decided to stay with 18s because it is the best compromise for me with the car's setup and classification.

POST 3Original post

17's are the way to go. Lots of tire choices and you will save $$$ over 18's Also for early year cars it not recommended to use 18's Square setup is what some people use, but the vast majority are staggered In 17's 255/40-17 rear and 225/45-17 front is a good setup for both AX and track

POST 5 / ORIGINAL POSTEROriginal post

I like the idea of using a balanced setup, it would possibly save a few to be able to rotate... 18" is probably out, rims are expensive in that size and what would I actually gain? 5mm? Besides, a smaller rotation on the rim with that same size profile tire would be a faster RPM on the tire anyway right?
