I put on a set of 22" Techarts (had 20" cayenne design) on my cayenne s and had a few questions:

Does this affect the accuracy of my speedometer? How can I get it recalibrated? Will my speedo be faster or slower than actual speed?

The tires are Pirelli Assimetrico 265/35 .. the tires have an m+s stamp! Is this an all season tire? Are they as performance oriented as my Diamaris that i took off? Whats the top speed?

Last but not least... I live in CT....just based on the finish of the wheel.. should i remove these during the winter? If this is an all season tire.. I was thinking to keep them on full time..

Thanks for the input!

Comapred to a 275-40-20, your speedo will be 2.2% too slow. When your speedo reads 60, your actually going 61.3.

I have the same wheels. I have z rated pirelli scorpions 295/30's, may be a better choice. The tread wear is 300.

The speedo is off a tad, IMO not worth the time or money to try to recalibrate and hope someone does not mess something else up. Your Cayenne cannot go fast enough to worry about the tire unraveling at warp speed let alone Pirelli Assimetricos. I have Pirelli Scorpion 295 30 22 on my CAY-s and living in SOCAL i cannot comment on foul weather like snow or ice. However from previous experience w/ Assimetricos on a car, they sucked in rain, however this was also on a RWD car, not a 4WD truck. IMO i would swap the stocks back on when it is foul weather outside or at least for winter season. I always tell people keep your stocks. You never know when you will need them again.
