you live in vegas and you don't want to lower your car??? why not. its not like you have to worry about anything out where you live.

go to www.tire.com plug in your current vehicle info and they will tell you what size tire to get if you go up a rims size or 2. just to remember with tires, you'll sacrafice performance for wear and vice versa. so if you want a real sticky tire that handles great its only going to last you 10,000-20,000 miles, or you could get a real shitty handling tire that last forever.
