I googled a ton, and didn't find what quite fit my needs, so any advice would be great. Have a 2006 CTTS, and would like to upgrade to Turbo II or Rinspeed wheels. I would like to have 21" or 22" with the thickest rubber I can get. I've seen some 295/40/21 tires, and some 285/40/22 work with a little luck. The problem is that I see gravel roads from time to time, and not sure at 35 sized tire would work. Roads in NC are pretty good, but a pothole does come up every now and then. Does the 40 sized tire protect the wheel that much better than a 35? Should I just buy the 305/35/22 wheels and tires, and just expect damage if I'm not careful? Does anyone offer a warranty if I do damage them?

Thanks a million for the help!

Anyone?

I sold my aftermarket 22s and replaced them with lighter OEM 20s from a 958 GTS. Suspension works much better now IMO on my 957 GTS.

The max I personally would go for on-road use (smaller for off-road) is up to 21s.

My 06 CTTS had 22's When I bought it. They were inexpensive wheels and would not balance well. Went with 20" OEM sport technos. All good.

You won't have a problem on dirt roads. You could take it off-roading anywhere you'd take a car with 20's. The difference is rock crawling might scratch the rim from the rim itself being closer to the ground. The durability of the tire is going to be the same as the 20. That little bit of extra sidewall isn't going to help you much. There isn't anywhere I wouldn't take a 21" GTS wheel but would take a 20" OEM wheel. I might go a tad slower with the GTS wheels when truly off-road, but for a dirty road, I wouldn't think twice about it.

The other reasons people have mentioned are the reasons to go with 20's over 22's.

You say what you want but you don't say why. That would help us give advice.

20's rubber is cheaper...

Choices for 21" tires are limited. 22s are too big IMO. One of the 957 CTTS I drove and 22s and it didn't ride well at all. The one I bought has 21s, which are much better, but I'm also considering a move down to a 20" to have more tire choices, less expensive tire choices, and more sidewall for the proper look on an SUV and better ride. If I had 22s, I'd definitely be changing them. With the 21s I'm not in a real hurry if that tells you anything.
