Where is a good site to buy reasonably priced wheels and tires

 

I like Americanmuscle.com they seem reasonable on price and have a pretty good selection.

 

I say find the exact ones you want then search around for the best price. I ended up buying off of ebay on my last 2 sets of wheels. www. Discounttiredirect.com for tires all the time. They price match anyones price.

Would I be able to go with a wider tire in the rear without having to do anything to the car itself?

 

yes you can.
