I have the same ones except 10 ply truck tire on my 2015 ram and had to change the back ones because they were worn by about 50,000 klm. and put the front ones to the back and they were cupping but not as worn out and put some brand new ones in the front . The tire shop told me the cupping problem is because the shocks are too soft and they are supposed to be heavy duty shocks on the truck from factory. So I changed the shocks all around and went with Bilstien 5100 and what a difference in ride way better . I would hate to see the factory normal shock they would put on this truck go figure factory would put on the cheapest shock but call it heavy duty cheap bastards
