Some interesting replies I've been reading. I may stick with the 17" rims after all. Here are a couple of more questions:
1) Not too crazy about the 17" rims that comes with the Titanium model. They would be a pain in the ass to clean. What 17" rims would you prefer?
2) I noticed on the 17" rims they come with Continental tires. These are the same tires I have on my Altima and quite frankly they're not very good. Noisy on the highway and lousy in the rain. Any suggestions as to what all-seasons you would switch to? Yes, I'm going on about tires again but at the same time that's something a lot of people overlook and I want to make sure that I'm doing the right thing. I do have a set of winters for the Altima (Michelin X-ice2) and I could probably get another winter or two out of them. And I'm sure they'll fit the Focus.
