Be very careful about buying anything from Airfreetires.
Please look them up in Google. You will find a long list of people who have ordered tires and never received them.
Air free tires is run by Hugh Waters. He says on his site that it takes four weeks for custom orders. I've been waiting for 8 weeks. They also say they return calls and next day and that you can look up your order info. I've never been able to get my order info. Hugh Water's company has replied only twice to the 14 calls, 1 certified letter, and 2 faxes I sent them. I've asked for a refund, but instead of responding promptly as promised in his website, airfree has yet to tell me when I will get my money back.
Airfreetires has 19 consumer complaints from the BBB this year alone.
The technology my be great, but airfreetires is not the company to buy from.
