We've been getting Dunlop A/T tires for our Suburban and they can supposedly get 30,000 to 50,000 miles on them but we only get about 15,000. Does anyone know if there is something wrong or if there's some way to lessen the wear? I hope you don't blame my driving style. (And don't blame the tire because it happened with the Firestones we used to get too.) Also, it seems to me that the tires wear more when they are on the rear, even though my tire guy says that's not so, but with rotation it's difficult to make that distinction. I'm thinking of getting two new tires this time (only the tires that are currently on the rear need to be replaced), put them on the rear, and not rotate them to see if they really are wearing faster. What do you think?
