I just got back from buying a set of Toyo RA-1s from Radial Tire Company in Silver Spring, MD. Paul there was recommended as someone who knows racing tires by Brian Garfield's dad (Brian is the SCCA Autocross instructor and his dad had a dealership and actually sold Cobras in the 60s) Anyway, Paul recommended the Toyo RA-1s also, told me the size he would recommend and everything. He understands racing etc. Their prices are good, same as you would get on the internet anywhere and for racers, the mounting and balancing was only $8.50 a tire. There was the usual MD environmental fee of $.80 per tire plus tax. They appear to be a very popular dealer from the number of people and cars there. AND, they give great customer service. I had dropped one wheel and scratched it. I had actually gotten the wheels mounted and had put them in the car. When I went to pay for them, Paul said they would fix the scratch, he went out to my car, got the wheel back our, took it in, the tech pulled the tire off, buffed the scratch out, remounted the tire, re-balanced it --- all for nothing. I was in awe. They have a good stock of tires, autocross and racing. The Toyos were in stock.
Everything about this dealer is first class. Again, this is Radial Tire Company, 9101 Brookville Road, Silver Spring, MD. Their phone number is (301) 585-2740. Ask for Paul if you have racing tire questions. I highly recommend them.
