huge change in smoothness ride, i dont have air ride so this change is in my opinion the best thing you can do to your cayenne!
any one says that it will couse problem with abs/psm etc is bull.

it is now more accurate in the speedo, before 5km/h to much now 2km/h to much.

other cons is the more goodlooking wheel that fill out the whellgap better.

hope i convince somebody to trie it out next time you bye new tire!

I did this several years ago.

Other benefits in addition to above:

M+S
Treadwear 500 - Original tires were good for only about 15K miles
Less flat tires - the stickier original Michelin tires were nail magnets

Oh yeah - Significantly less cost

I gave up some performance, but that doesn't weigh in with me. I'll try to keep it under 130 mph, otherwise I did not notice much difference.

 

Exactly! much more wearpattern! Do you think 275/50-20 is to much? Heard someone in this forum got mixed up with 275/55-20 and that rubbed the fenders i think, maybe good enough with 45 profile?

 

I have sport techno wheels in 9/10" staggered fitment and recently switched to Yokohama Parada Spec-X in 265/50-20 and 295/45-20 and recommend them wholeheartedly.

 

Thumbs up on the Parada Spec X , I have them in 275/45 r 20 on my CTT and they are great . They fill out the wheelwell better are smooth and quiet too. love 'em

 

I should have done this but the P-dealer scared me the fact altering the tire size would resulted in forfeit the factory warranty coverage on drive trains & suspensions.

Oh well, will do it next time around

BTW, looks good!
