The cupping on my last trucks offroad tires were only solved by cross rotating......front to back and back to front just never helped at all...which is what I would expect the dealer to do so he could sell me more tires.....I had to figure it out on my own.
I noticed to go straight down the hiway I had to turn my Titan steering wheel about 1" to the right of center......took it in and they aligned the front end...now the wheel is dead center going down the hiway. When they change the air pressure sensors next week they will rebalance , road force test and cross rotate the tires. Will be interesting to see if the mpg's are effected for the better after getting things smooth.
