anyone running the above listed tires on there lt duty trucks? if so what amount of air pressure are u running for everyday use, no loads or towing? tire rated for 80psi but seems a little to much for normal driving conditions. Any suggestions on a psi for normal driving? load E range 10 ply and truck is a ram 2012.

Not that tire but a lot of people run the 80# tires at 65# if your tpms system will allow it without an alarm.

What is the weight on the tire? Single or dual rear wheels?If you know the axle weights, you can look up in a table from the tire manufacturer (or really any maker of the same size and type and weight rating of tire) and see what the appropriate inflation pressure is for your weight. 80 psi would only be appropriate around the maximum rated weight capacity of the tire, which I'm pretty sure you're nowhere near in everyday running around.If you don't know the axle weights, the door sticker would give reasonable information for the maximum payload of the truck, if these are the stock sized tires for the truck.

on my duramax the door placard has two PSI charts. one for towing, one unloaded. unloaded I run the unloaded PSI, IIRC around 65psi. On the gm 65psi doesn't trigger the TPMS alarm.And I had the dealer reprogram the TPMS alarm system to 55psi all around. easy to check tire pressure on the dash, and it makes sure I don't get an errant alarm.

Ideally, you need to weigh your vehicle with a full load of fuel and everything you normally carry, including passengers.You can find your nearest CAT scale here:https://catscale.com/Once you have ACTUAL weights for your axles, you can find various brand tire load charts here:https://www.escapees.com/education/smartweigh/forms/#tireinfo

50 psi would be a good place to start with those 20" LT E tires. Watch the wear especially on the front axle with a heavy diesel engine. Lots of city driving can wear the edges.

Thanks for all the responses and suggestions, i think I am going to put 50psi in all 4 and see how it rides and go from there. will increase when towing our TT... give a update in a few weeks.
Again thanks for all the help...

WHY guess? Weight it loaded and unloaded then use the weight/inflation chart.

I quickly wore through the center of the tread on the rear tires when following the door frame sticker pressures on my old truck. I settled on matching the front pressure when lightly loaded, and using the sticker pressure only when heavily loaded. Tread wear is much improved.
