I just bought my set from Discount Tire (www.discounttiredirect.com/direct/home.do
), and couldn't be more happy. You can PM them here (Discount Tire is username) and ask questions about everything before you make your purchase. Very helpful, knowledgeable and friendly folks. They also offer a $50 discount for Wrangler Forum members, if you mention it on the phone. Free mounting/balancing and shipping to your door.
Good luck, and post pics when you get them!
