you can take this with a grain of salt, but this is my take on the air pressure.The standard tires were rated at 40psi. So,,now I’m wondering what PSI I should stop at? Should I go to 60? 65? 70? I’m gonna stay at 55psi for a little longer and see if anyone has any input before I change it.
I have run 8ply rated tires on my 98 Chev K1500 since I bought it and maintained 50-55psi in them all the time unless I plan to really tax the payload of the pickup. And it has been ridiculously loaded more than once.
When I bought new tires for it a couple of years ago, the tire people only filled to 35-40, and even unladen the ride seemed too mushy for me.
I have filled them to 65+ just to see what it would feel like and unladen it was not pleasant at all, and this truck rides real nice and absorbs bumps nicely.
However, 50-55 seems to be the sweet spot for ride comfort and normal type filling up the truck.
Rides nice without being mushy, will carry a reasonable load, tires stay round for less drag, and I actually get better fuel mileage than with then filled to 40 and under.
anything over 55 will likely affect ride/comfort, two items that are important to me.
Have to say tho, this new truck rides nice, but not nearly as nice as the older one. But it does feel a lot more responsive and positive in it‘s footing.
