Anyone running 235/85 with 16" rim on a half-ton? Sam's sells them for vans and delivery trucks. They look tall and skinny kinda like the original bias ply tires and might get my rig going a little faster down the road.

Those 7" and 7.5" bias ply mudgrips look good also, but they are NOISY.

These specs are for D (8 ply) and E (10 ply) load range tires, taken directly from the Michelin Data Book. I don't have weight specs, but neither size weighs more than perhaps 70#s max.

I'm running 235/85-16s on my half ton, they are too wide for your stock rims.
I had the centers cut out of my stock rims and welded on to new outers that are 7 inches wide bead seat to bead seat, that's roughly 8 inches outside width.
Zero offset (neutral)
That is the widest rim you can run with your stock tie rod ends.
It is perfect, the tires fill out the wheel wells very nicely, the truck can run modern tubeless radials and the wider footprint adds much stability without sacrificing steering ease.
I am very satisfied with the way it came out.
