Re: 18's or 20's?
I bought a Limited last December with the 18's. I traded it in April and this one has 20's. I can say that the 18's ride smoother, but it's not a big difference. Then again, I switched to 22's on my last SUV so I knew what to expect. The only big difference is over bumps or bad spots in the pavement. I get more of a jolt in the steering wheel. The 20's for what ever reason, just seem to handle better and turning the wheel seems tighter and not as sloppy. I am very happy with the change.
