My 2013 Coachmen Concord came with a set of Generals that seem to want to shake my teeth loose. Had several of the tires road-force balanced, and they were way off. There's less than 9000 miles on the rig. All of the local General Dealers tell me that they don't handle warranty on the tires, so I'm considering looking for a new manufacturer that isn't so difficult to deal with, and makes a quality tire. I'd be interested to hear some input as to what everybody else has had good performance from. Thank you in advance for your input.
