I bought 2 tires sold as New/unused tires off eBay and where highly discounted, Dunlop SP Sport Maxx GT's size 325/30 20. Tires arrived and both had a manufacture stamp on the tire of 2012 so old warehouse stock. The tires where never mounted and, still had the colored lines on the tread, but the tread it self felt hard even after tires had warmed up in 70 degree environment. The sidewall rubber is soft and pliable and you can dig your finger into the rubber and it feels right. The tread however feels harder and does not give much when you push your finger nail into it, even a flat head screw driver pushed into the tread rubber leaves a mark that stays there for a while. Question is are these tires still good as there is so much conflicting information on the web. Some say tires never really go bad if stored inside and in cool dry climate and other say they are dangerous. After talking with Tire Rack and Discount tire they both say tires should last in a warehouse up to ten years without deteriorating. Europe has expiration standards on older tires, but apparently US has none, and nobody really knows for sure. Here are the tires and date stamp on these tires, and buy the way when I use a heat gun to warm up the tread rubber it gets softer and more pliable, but they still seem hard compared to my almost New Nitto G2's that are 4 years old.
Should I run these tires or send them back?
