I think it's great.
Would you take your tires back after putting 75,000 miles on them and ask for a new set? If you did Goodyear and the retailer would laugh you out the door. Or, maybe they would shoot you in the face.
Businesses outside of the 'Outdoor Industry' require the consumer to be responsible for wear and tear. Why does outdoor retail somehow differ? The retailer should help you contact the manufacturer if there is an issue with a product that falls within the manufacturer's warranty.
All products have a life. If you bought it and you break it you broke it. If you buy it and it is truly defective then let the company know and they should make you happy if they made a bad product.
Most brands have good warranties.
By from a local shop and they will help you get your product warrantied if need be.
Good Luck
