I ordered all 4 tires and they only lasted 7 months even when properly inflated. All 4 had stains around the edges and one leaked on the motorway 7 months after purchase. I think you get what you pay for, right?
these tires had been on my antique truck for a year two of them started deflating i took them to the local ford dealer to check and the sidewalls were falling apart inside. They have less than 1000 miles on them and are already junk. I hope the other two hold up!
