Question for you guys. If I go to an 18 inch wheel instead of a 17 inch will their be a difference in the smooth drive of the car.

I love the loook of the 18's but have been told if I go 18 the ride will not be as good in the car.

When you go to bigger rims you trade rubber for metal. More rubber=better ride. Less rubber and more metal =harder ride. It's as simple as that.

Iam going back and forth between 17's and 18's. Anyone know of a good place to buy them online in Canada? A set of wheels with tires here in canada is $2600 and in the US the same wheels are $1500. Whata rip off

Ride quality isn't just a function of rim size. The tires you buy make a huge difference. Trouble is, the tire industry still thinks that anyone with 18 inch rims must want a performance tire so ride quality is one of their lowest priorities. Fortunately, since 18s are becoming more popular on new cars, that should soon change.

My new CTS has the 18" and I love the ride.. I love the nav too..

My eyes are all over on this car.. The front end has that mean agressive look to it.

18s with 245/45-18s and 17s with 225/50-17s have about the same amount of sidewall. Just buy nicer tires, don't go cheap and you'll be surprised how good the vehicle will still ride.

I have 235/35-19s on mine and I love the ride, its not harsh nor unforgiving over bumps like you might think, but then I'll credit most of that to the BFG KDW2s that I am using.
