kkswow12 would 245/30-20 work for the front? or was 245/30 rubbing also?
245s should give you more sidewall

 

Never liked 20's on 997's. I think they look out of proportion to the car - sort of cartoonish. Not to mention the tires look like rubber bands. I think you made the right decision.

 

I love the look of the 991 classic 20's wheels. Wouldn't mine having those on my car. Are there any 997's with them on? I would love to see it.

With regards to rubber band, IMO the factory 19's tire size would be considered "rubber band" on many cars since the sidewall is <= 35%. But they look great. :-)
