18-inch stock rims - how much rougher is the rid?

[GTO Lover]

Is the ride much rougher on the low profile 18-inch wheels vs. stock 17s? What tire pressure do you keep in your stock 18-inch tires?

The ride is not noticeably rougher in my opinion. I had an 04 with 17's, and now have a 06 with 18's.

I have stock 18s on the Torrid Red and stock 17s on the Phantom Black. It is a noticably different ride in two ways. Yes the ride is a tad rougher but not much. The 18s handle the corners much better but this may be more due to the tire than the rim size. 17s come with all season BFG KDWS and the 18s come with "summer only" Bridgstone Potenza RE040s.

Ride quality isnt bad. I keep the psi at about 35 all around. Im not keeping the 18's on though cause I want something wider in the back. Grip is not too impressive...

The ride is actually smoother on my 04 with the 18" wheels and Potenzas. I run 35 psi.

i didnt notice a difference when I uped on the wheel size.
