When people post that they are happy or pleased with their tires is that because they haven't had a flat or other problems? Are there other attributes of trailer tires other than peace of mind. Do some track or stop better? Is their traction important especially when they need to scrub when backing up? Would some put unnecessary strain on suspension components because they don't side slip easy enough? I've always wondered why manufacturers would go to the trouble of designing, manufacturing, stocking and marketing ST tires when they already have superior products in their LT lines.
