Yeah I have the cayenne hybrid 5-spokes from a 2011 or 2012 on my 2004 CTT and they fit. My 20" sport technos also fit on my 2011 cayenne.

Sorry to raise up the old thread, but I'm particularly interested in putting these tires (TerrainContacts) on the stock 20in rims of an 06' Cayenne Turbo S. I'd love to drop to 19in rims (and I think the brakes can be cleared by 19s) or lower, but it's more money than I want to spend.

What are people's thoughts about the TerrainContacts in either 275/55R20 (32in) or 265/60R20 (30.5in, but slightly narrower) on the stock 20x9 SportTechno rims.

Over the past year or so I've run the Terrain Contact ATs in 265/50 20 (30.4" is as tall as can fit on a 958) and they've been fantastic. They are just as quiet on the road as summer or A/S tires, and effortlessly handle deep sand, rocks, and deep mud with no problem. In deep snow they are so-so, but that is any non-snow tire compared to a real snow tire.

@garrett376 That's super helpful!

Any issues fitting on the 9" wide rims (assuming stock 9x20s)?

Thanks. I'm also looking for a good 20 inch all terrain tire for my 06 CTTS. Mostly for forest service roads in southwest Colorado this summer.

No problem - TireRack says they work with a 7.5-9.5" wheel.

Their 275/55R20 size has a 31.9" diameter which might fit the 955/957, as the Transsyberia tire diameters were 31.7" in diameter and fit OK. The extra 0.5" ground clearance (265/50 20 vs 275/55 20) may not be worth the possible rubbing issue, though.

Those running with regular springs, has anyone replaced it with coilovers? I wonder how high you can get with adjusting the coilovers.....Bad idea?
