My wife wanted to use a different shop, and got the Nitto Recon Grappler ATs we wanted installed. Problem is they are not the E rated variety, and now we are stuck with them. Truck is used for towing a 34 ft trailer, about 8K lbs. Tire size is 275 60R 20, truck has a 2.5" icon suspension lift, and I use a wt Distrubution hitch as well as Timbrens at the axle. Im hoping that the 20s will have a shorter sidewall for flex, but anyone feel this is totally unsafe to tow with??
