I have Cooper Discoverer M&S LT265/75R16 load range E on my truck. It says Max Load 3415 at 80 psi I am wondering what pressure with no load ?? and what pressure when towing my trailer 1700-lbs, race car 2800-lbs, and gear 500-lbs and 2 people 200 each ???

 

I keep mine at 50 to 55 psi for all useages. If i was to have a lot of rear weight i would air them up. I got 67,000 on my oem michelins. Remember a lower pressure and under load creates a lot of heat which will destroy a tire. Thet recommend a higher pressure for a reason. Plus you should get better mileage with the pressure up.

 

On the door sticker it recomends 65-lbs at 5200 front and 80-lbs 6084 rear but that is with LT245/75R16 tires with the LT265/75R16 I would have thaught thay would take more pressure????

 

Just because a tire is bigger in size doesent mean the more pressure that it takes it just means it takes more air in volume to get to the recommend pressures. Look at the very large off road tires most guys i know put like 25-30 psi in those tires

 

I run my Michelin LTX's at 65 front and 70 rear. They are the original tires that came with the truck new and they have 73,000 on them. They are now needing to be replaced.
