That's reasonable, our roads are bad here too. Ive even bent my 23 lb 17" focus SVT wheels..Hmm... I think I'll stick with my heavy wheels. I'd rather have a few pounds extra than be replacing them every time I hit an unseen pothole. There are enough of them around that I can safely say I'd be saving thousands on avoided replacements.
But, I do enjoy seeing you guys put such fancy wheels on your cars.
