check out ebay and tiresunlimited.com
a few years ago i use to buy tires from cedar city tires. do a search on cedar city.
sometimes shipping can kill the deal,..if you have a local Discount Tires,..they are fair on there shipping charges to your local store,... on carlisle tires.
at least they are here in az.
the carlisle r/s series has a nice round profile.
hope that helps. ...:thumbsup:
