Looking to spec a new Cayenne. Can sombody explain the advantages of 21 or even 20 inch wheels please. As far as I can see there is non - all disadvantage (replacement cost, ride quality, rim vunerability, mileage). Ok might be worth a few tenths on the 'ring but I'm not planning to go there in the Cayenne - so why should I spend the extra?
 
The old Cayenne really needed bigger wheels to compensate for the bulk of its shell. However, the new Cayenne is far more svelte, and can wear smaller wheels.

19"s and 20" will probably be most popular. The bigger the wheels, the greater the benefit of the PASM and air suspension options. Space-saver spare is probably worthwhile, and the nco 'all season' tyres.
 
I thought the car was developed on 18" wheels. I can see that if you fit 19" or bigger wheels air & pasm will help the ride quality. Isn't there a weight penalty the bigger the wheels?
New model is certainly more agile, more car like and this may make the use of bigger wheels more acceptable but does it mean there is an advantage to using them?
I know visually the appeal to some - but half the salesmen I've spoken to could'nt be sure what size wheels were fitted without checking - so I'm still looking for some dynamic or economic reason to fit them .
 
The bigger wheels have little dynamic or functional benefit - the main attraction is aesthetic. I suppose a Cayenne turbo with big PCCBs needs wheels that clear the discs and callipers.

Personally, I would have thought 19" or perhaps 20" would be the best compromise, and 21" and above would have more disadvantages than benefits.

For winter use 18" with appropriate tyres probably make the most sense.
 
If you want your tyres to last twice as long keep the 18""
standard .That was the consensus here when discussed before
