Bought a Chevy 3500 with Rydanz 245/75R16 10 ply tires. Might have put 5000 miles on truck in three years of owning it. Noticed a "shake" in the front a few months ago when used last. Go to use it couple of days ago and it about shakes off the road. Stop,check tires, front driver is humped up in the tread area. Busted belt. Look at others, they appear Ok. Limp back to park it and order some tires for front. Next day looking at truck and see the right front and outside left rear showing signs of busted belts. This morning right outside rear has a "warp" in the tread area.
