Tires and towing
I bought a new 2014 F350. I lifted the truck right away, 4" and put on a set of 20" wheels and nitto Trail Grappler 295/65-20. I put the tires on and towed the same day with HORRIBLE results. The truck was all over the place in the rear end. the trailer is an Attitude 23AK, 23' Toyhauler. The trailer was loaded EXACTLY the same way it was when I towed it with my stock F150. the F150 drove straight and true, it was just too much weight for it day to day. The trailer in this case was at about 8500lbs on a mild windy day. We also just bought a nice 28' Race trailer and the truck did the same thing. trailer was empty and the nose was just a little down when hooked to the truck. 2 trailers, Exactly the same feeling/issues. It feels like the back end is on ice and sliding around. Rear tires are at 80psi per spec.
My question is, has anyone else had issues or experience with a bumper pull trailer and these tires?
I have the stock 18's sitting in the shop, so I think I will have Discount tire put them back on then do a test pull. I think I has to be the tires.
The lift is a 4" BDS lift with basic fox shocks all around. The stock rear blocks are 3.5" and the lift blocks are 5". I have a very hard time thinking they affect anything. The front was springs. Everything on the suspension check out tight. I bought a Rear sway bar for it after towing the first time, and that made no difference on towing.
I really need some help here as I need to tow for work, but this truck won't tow for crap. there are Very limited tires with the load rating for the F350 in this size, so I might just go back down to stock size where there is more selection.
