Don't normally go around honking others horns but Tire Rack is a great place.
Just had my first experience with them getting tires for my 70 GTX. The on-line store was a breeze, they followed up with an email questioning the size choices (politely) with a number of someone to call. I called, without waiting for ever, the guy was nice and knowledgeable. He followed the phone call with a 'thank you' email. They shipped the same day. Prices and shipping costs were very reasonable. If you can beat their prices by $5 each I would be surpised. For sure you won't beat their service.
I don't work there, I don't know anyone who does (except now Roger). Just wanted to share a very pleasant experience. Doing a ground up on my car and there are not that many

 

I have also had good experiences when dealing with tire rack. I have ordered tires numerous times for my truck and have nothing but good things to say. Hard to find quality like that these days.

 

I swear Tire Rack is unbelievable! Needed tires for another car (forgive me it is a Volvo). Went to the Tire Rack site looking for 255/50ZR19 replacements for the Pirelli's on it. Really wanted the Yokohama but they only showed 2 in-stock and they are in Georgia. Had to have the tires now so I just bought the Pirelli's. 2 hours later Tire Rack calls and the guy tells my wife they have a better tire (the Yokohama) for less money. I call him back and tell him the web did not show 4 in stock. He says they just arrived and can ship them. I get the tire I want, they are $45/corner cheaper. They shipped today.
