I am on my fourth tube since the first of the year. Two were from Tiwan and one from India. They all failed at the seams. Two were in the area where the valved is attached. I got the first two from Coker's when I bought new tires, and the other two from Mac's. I have rim liners and the wheels are powder coated, so no hazzards there. Anyone else have similar problems? Mac's tell me they have had no complaints; so will not give a refund. One tube failed before I even installed the tire on the car. Anyone know where I can get American made tubes?
