Airfree and Nu-tech are the worst...
Purchased some tires from Airfree - Nu-Tech (700x28, 90PSI) against the better judgment of others. The tires weren't even made correctly. The support cords on one weren't molded into the tire all the way making it un-usable and the other has a hard spot that is so bad that the bike wants to come apart over about 12 MHP. Multiple E-mails, support tickets, calls and I received nothing in return. Visa wouldn't step in since I tried to give the supplier a chance to correct the defects and went over the 30 day time limit. Save your hard earned money for something worth having....
