Tires and towing

[rocnrol]

Anybody towing with the BFG Mud Terrain TA KM2 in the larger sizes? Specifically, I'm looking at going to a 35 12.50 18

I haven't...but the tires you're picking out are a load range D tire that are a little bit taller. The increased height would be more concerning to me than the LR unless you're maxing out your truck. (increased diameter lowers (numerically) your effective gearing impacting acceleration and cruise RPM)

Will a shop actually install a tire less than the rating of the stock tire? Doubt it.

While I can appreciate your concerns, here's where I'm at. My factory tires were rated at 3525 lbs max load at max inflation of 80psi. Right now mine are inflated to spec, I'm not looking at the door jam, but my onstar app is telling me that the rears are at 75 psi. There for, the load capacity will be less than 3525 lbs.

 

The BFG's are rated to 2910 lbs max load at 60 psi max inflation. Don't see there being much difference here. Just looking for someone's personal experience with towing with these tires

My trailer is on the heavier side on the tongue, but it's only 1100 lbs. Use of a weight distribution hitch will put some of that to the front, so at a combined load capacity of 5820 lbs between the two tires, I'm not concerned. I'm very aware of the situation you have expressed with the height change, and I'm prepared to accept the loss in performance.

Sounds like you got your bases covered.
