What's the widest tire that will mount on the stock 18" AMG wheels without screwing anything up?

which AMG's? I see in ur profile C63 they are different 18's than the 300/350 come with. if you have the split 5 stars from the 300/350 its a 245/35/18 stock, you could actually go to a 255/265 if you wanna go real fat, I dont think it would look good but your call. If your talking about the 5 star stock C63 wheels I beleive its a 255/35/18 stock, you could go 265/275 but then again weird look kinda loke dragstrip wheels look. You wanna get a wider rim if your gonna get fatter tires to keep that low profile look unless your just gonna use them for racing or something like that

That's why I said on stock rims. They are stock 2009 AMG C63 rims. In most cases you can go up one size but I have no idea what size I can use.

You'd be better off posting this in the C63 forum. You can go up one size to 265 in the rear from what I've read. jimmythegreek is right, the C300/C350 come with smaller 18" wheels and cannot accommodate wider tires that would fit on the stock C63 wheels.

Sorry, I took a wrong click on forums.............thought I was in the C63 section. I was in a hurry.
