TV tire pressure ?

[Andy]

I have a 2500 Chevy Silverado diesel. Question. Why does is say to put 60# of air pressure in the front, and 80# air pressure in the rear tires. Personally, it would seem that if you're hauling weight in the the truck it would make sense to have more air pressure in the rear tires, but when empty, not so. Considering that the largest percentage of time the truck is empty it wouldn’t seem to make sense to have more pressure in the rear tires, and would actually cause center tire wear on the rear tires. However, every time I have the tires rotated I make it a point to have the air in the tires adjusted to meet the manufactures specs. Hopefully someone will be able to shed some light on this for me.

Thanks,
Andy

I don't think you'll have any problem by lowering the rear pressure when not towing. On the other hand, I run 80 on the rears 90% of the time and have not had wear in the center. I merely don't know when I may want to latch onto the fiver and hit the road, and don't want to have to keep adjusting tire pressure. Only thing I have seen that suffers is smoothness of ride.

Yeah, that, you know, what slick said.

ME TOO, I know I can adjust to tire pressure down, when not towing for a nice cadillac ride. But I am TOO LAZY... I just keep them all up where they belong, so I can tow anytime I see the signal from Kotham City, (you know the BATMAN thing) with the Bat in the sky, Or when Robin Hood Call's for one of his merry men... I am ready.... Beside's keeping those rear duallies at equal pressure is my most important task. Oh for those with denture's A little more adheasive on those plastics will keep them solid, as you drive down that road. BRANSON IS GREAT IN 2008 see ya there John

Mine calls for 55# and 85#, the 85# is for maximun load. Almost always run 55# on all tires. Sure makes the truck ride better. I just air up when I'm ready to hit the road.

My Dodge has a sticker on the door that carries inflation recommendations for both "lightly loaded" and "heavily loaded." The front tires are the same 60 psi on both loads. The rear is 45 for a light load and 75 for heavily loaded. But I run 80 in the rears when towing.

It is to hard to inflate a deflate the tires on the dually so I keep them the same the same all the time...I rides like a truck..

I run my rear tires at 80# cold. I was running my front tires at the same pressure until my last oil change when the Ford mechanic reduced them to 60# (the door post says 55#). I asked him why and he said for better handling. I reminded him of the lawsuit between Ford and Firestone and he agreed that if you run the tires at the max cold pressure you wouldn't be wrong. So, I got out my last RVSEF weight record and lo and behold: the weight on the front wheels was less when loaded with the Montana than when empty. So, I now keep my front tires at the reduced pressure (60#). Handling is better, ride is better both loaded and unloaded. Sometimes methinks I think too much.
