Tire PSI - OE GY's

[PaleRider]

Hey all!

For those still on OE tires, what pressures have you found felt best for an unloaded / lightly loaded daily drive?

The placard reads 65F,55R,55s. When I picked up the truck, it was set to 65cold front, 55cold rear. It rode well but a little harsh. I adjusted that to 58cold front and 50cold rear. Seemed to blend harshness/steering input well at these pressures.

This morning I tried out 55front cold and 48rear cold which resulted in a little bit squirrely handling and a little extra tread noise/feeling until they passed 57psi on the warmup to 61.

Once the rain stops i'll do a chalk test, just curious what you've all found to be the happy zone.

'25 2500 with Duramax and Good-for-a-Years...55 rear, 60 front. I should probably drop the rear a bit more...Need to chalk the tire and look at my contact pattern.

I run mine 50-52 psi cold and 65 psi if towing. Rides and handles great!

For a 1500 or 2500?

Calling it a day at 50c x4 and 56-58 at temp. Seems to be the right balance

55 front, 50 rear cold

Tire wear at 14k miles looks pretty good, and way better than my ‘21 AT4 6.2!

Agree.

This truck rides much better than my last, which was a 2018 ccsb 1500 riding on a pretty trick mid-travel setup.

This zR2 is impressive. Just have to determine if mine could do with a pisk/locking eccentrics. My hope is not, but it is still a GM front end hehehe
