Also .... i was really amazed because with the 11.00r20 i can easily turn the steering wheel even without moving ... ok it's not on the pavement but it's easier turning the truck now with those big rubbers instead of the oem size wheels . And when drivng it .... ( doesn't go more then 20 mph ) the steering feel strong and it's not even moving or giving any bumpsteer .. Finally i'm not sure that i will rush to install a power steering unit .... probably will wait for the cummins swap
