tire pressure question

97 2 door yukon 4x4 , 265-75-16 bfg a/t's

best tire pressure for ride quality, discount tire put 40psi , rides stiff as hell, would 30 psi be too low under normal driving conditions

Load range? I'm presuming you're running load range D's, so 40 PSI is a little on the high side of the middle. I'd actually suggest about 35 PSI for proper tire wear, but you must remember that BFG A/T's have stiffer sidewalls than most tires and will ride rough anyway. That being said, you'll probably have to experiment with your tire pressure and see how the tires wear wherever you put the PSI.

thanks , that's what I figured

Mine had 60PSI after the tire shop installed the BFG's A/T...I dropped it to 50 COLD...gets to about 53 when hot...I put 2 80 lb bags of concrete in bed just in front of the tailgate..better ride...If you run tires at 35PSI cold I'd check the sidewall temp after driving about an hour...if they are too hot to touch I'd pick up the pressure a bit.

Mine are at 35.

 

50 is excessive for an empty 1/2 ton truck.

 

45ish max loaded 1/2 ton.

 

Running that high a pressure empty will wear the center section out of the tread.

35K and no sign of abnormal wear...

I've always ran around 40 in the front and 32 in the back. I get the best wear on the tires with this combination.

Are these stock tires or BFG's A/T's

Sorry shorepatrol2...that question was directed to tflessner...

 

I find running lower pressures the sidewall gets real hot and the MPG goes through the floor...
