Let's say I have 17's....

It's not which I should switch to, but should I? What's the advantage of the bigger wheel? Is the ride rougher but it handles better?

On my Cayman, I intentionally chose the 17's. The ride was exceptional, and the handling... well it was a Cayman, so no complaints at all..

Replacement time is when you really thank yourself!

This is a good test of 15", 16", 17", 18", and 19" wheels/tires. Bottom line: larger wheels yield small improvements in cornering grip at the expense of reduced acceleration, fuel economy, and ride comfort. However, larger wheels look better.

At the end of the day, you can justify whatever you want.

I think the only reason to go larger is looks. If that doesn't matter to you than definitely stay with the 17's. They're light and cheap(er). From a driving standpoint you'll never miss not having 18's or 19's.

Thanks. I like my wheels and have been wondering what I was missing. If I run across another original set of 550 anneversary wheels I'll buy those.
