So, I have to ask, does this mean I should upgrade my SRW F350 FX4 to rims/tires greater than an E rating. I'm carrying a Lance 1010 and had a blowout on new tires and tires had the correct pressure in them. I chalked it up to a fluke since I through this question out to the Board a few months ago.
Do the math! Weigh your rig, rear axle and then you'll have a much better idea if you need them or not. I know several on the forum who aren't near the weight requirements but like the safety margin and reduced sway the 19.5's give them.
When I FULLY loaded my TC I was a couple hundred pounds over my E rated tires. The truck "seems" to ride and handle just fine with my E rated tires and I haven't had any problems....yet and I could ask my wife not to load as much :B. I decided not to wait for a possible blowout and have my 19.5's on order.
