motorcycle superstore Lack of response Medford, Oregon

 Purchased two motorcycle tires from said company on Dec 12,2012. On April 3, 20013, rear tire went flat. Repair shop installed new tube and made me aware of a blister on the inside of tire. On April 12,2013 the same tire blew out. Contacted Motorcycle Superstore and emailed photos of tire showing defected tire. After shipping tire back to Motorcycle Superstore and after two months,I was told on June 17 2013 that the tire blew out because of "low air pressure" and they will not guarantee it. It's called a Blow-Out! They only responded after numerous phone calls made by me. The tire was shipped back to me, but it WASN”T my tire.

The total cost for having the bike towed twice, 2 - tubes & one replacement tire was over $600.00. I just want a refund of purchase price.

Again, I sent pictures of the tire and where the defective blister was inside the tire.This was the reason the tubes (2) blew out.  Along with the receipt for a new tire. They have not responsed to my many requests .
