Proper tire pressure for load range E 10 ply tires

Yes you can run them at 35psi. I made the mistake of having tires done on my new 1/2ton in 2008. They rode rough and it wasn't until a few days later I checked the sidewall and sure enough they were e rated tires. I should have taken them back but didn't. Ran them at 38psi for 4 years until I got rid of the truck. I suggest to keep an eye on them for the first couple months to make sure they are wearing good and adjust pressure if needed. Even run them at 40spi if the ride is good.
