Ride quality: 18 to 20: M 310 Double Spoke Rims
 
There is a great deal at my local dealership to pick up the 310 rims for $2500 with the P Zero tires. My concern is the ride. Will it be substantially stiffer and harsher over potholes? I find the 18's ok and a little stiffer is fine, but what would i expect going to these:

20" Alloy Wheels
Pirellli P Zero Run-Flat
245/40R20 Y, Front
275/35R20 Y, Rear

@ bichoo, Does your car have the dynamic dampers?

I would think you would notice a harsher ride with the bigger wheels but if the car is equipped with the dynamic dampers it may be less of a problem.

The staggered setup my be more prone to tramlining though.

Yesterday I went to some local shop to try some 20" aftermarket rims.
Looks to me that 245/45/20 for fronts and 275/40/20 for rears fitted much better than the standard 245/40 and 275/35.

I didn't try it for how it feels as I was just trying to see if those can fit.
Any thoughts on these bigger wheels ? anyone tried this ? I would assume comfort-ness would be much better than the 245/40 and 275/35

Did you get the 245/45/20 and 275/40/20.
If so please post pics. I'm looking at the same with Stance-5 Black rims with the same size tires.:)

I'm interested in this too. Which dealer.... lol

hey SHABSX3M, no I didn't end up getting the 20's and instead got the 19" 369M. It looks great and I'm happy that I chose these wheels instead of the 20's
