Since I needed new skins on the back of the D250, and I didn't have the $$$$ to convert to Ricksons; I had my local shop install some new 235/85R/16's load range E. Driving home when the truck was accelerating past 45mph, the whole back of the truck started to sway; like there was an improperly loaded trailer back there. Got home, checked lugs they were fien. Took it back to the tire shop and the took it for a ride. The owner couldn't believe how bad it was. It appears I got a defective tir from the mfg. New one will be here monday.
