I'm looking at two '08 Silverados today. They are identical except one has the factory 20's and the other has the 8 spoke 22's. Can anyone give me information on the ride quality of each? Both are 2wd crew cabs. THANKS

 

20s will ride smoother. The more tire on teh wheel, the smoother the ride.

 

You would also be able to carry a little more weight with the 20's, more sidewall to play with. If you are only using it as a sport truck, the 22's will hug the road.

 

My new truck rides much better with 20" then my old truck did with 22"
