Tire cupping 1
Posted by James from Pineville, LA, VI on March 31, 2009
I have a 40′ class A motorhome with 6 G670 Goodyear 22.5″ tires. The two front tires are cupping on the outer tread, worse on passenger side. I have about 18,000 miles on them. Cupping started immediately on passenger side and at about 17,000 miles on driver’s side. Would one of the on-board balancing systems, such as BALANCE MASTERS, or CENTRAMATIC makes, be expected to remedy this problem? The motor home is less than 2 years old and was purchased new. Chassis is Roadmasted by Holiday Rambler-gone belly up so no warranty as far as I know.
These balancing systems may help your cupping issue. I suggest moving the steer tires to a drive position and move a couple drive tires up to the steer axle. The worn tires on the steer axle should wear smoothly for the rest of their treadlife and the tires you move back to drive might "clean up" over time.
