Load Rate E or F for 2500 wt Cummings for 4x4 and pulling 10Klbs?

[Andy Owen]

I'm looking at getting new tires, I prefer M/Ts for the looks and dirt performance, but I'm hoping to see the country with a 26' airstream next. I'm running ironman 35x12.5r20s and think that I may need to graduate to F load ratings for safety, potential loads. and maybe get the air pressure dummy light to stop blinking.

Should I spend the $250 to get the F load rating tires, or are the E's adequate?

Thanks

For a 26’ airstream E should be plenty. I think the Toyo are 4000lb rating.

The Nitto Ridge Grappler 35x12.50R18 & R20 tires are a Load Range F spec.

I had the BFG KO2s and much prefer the Nittos.

Got a question for you. What's a "cummings"? It shows up in the title of this thread and your profile. Just curious...

Are you going to carry the entire weight of the trailer on the back of the truck? No, you're only adding the tongue to the pick-up. No need to go to F rated tires. An E load rated tire will be plenty.

Thanks everyone, Cummings is mispled Cummins; wait to you get old, 35x12.5r20 10 ply E rated 3195@65psi and deal with the pesky low pressure indicator light. Enjoyed our discussion and love my truck.

Get alphaobd and change the TPMS thresholds. or you can get a set of 295/65/20 tires. They are a little bigger than 35x12.5x20 Same E rating but at higher PSI. Factory load rating is E for your truck so there is really no need to go to F.
