I'm going to run theseI can't say what would better for you...what is your weight?
I ran the most aggressive Michelin 19.5's, had them sipped...the traction was horrible but I use my truck on slick boat ramps, on fire roads, etc. I ran them at 80 psi, the minimum required to keep them on the wheel. Ride was stiff, not intolerable but my new truck rides like a caddy compared to it.
If you have the wheels and can't return them...run em. Mine were loud, tracked poorly and rode harsh without good off road traction. However, I NEVER worried about weight or overloading them.
Weigh your rig, go with your best options. Best of luck.
