I've been thinking about getting a set of tire deflators and have a question about tire pressure. Normally (pavement driving) there's a 10 psi difference from front and rear tire pressures. Does this difference in pressure need to be maintained when airing down too, or should all four tires air down to the same pressure? I only ask becuse if the difference is kept I'd like to somehow mark two of the deflators for "front" pressures and the others for "rear" pressures.

 

First, don't use tire deflators for in town driving they are only for off road.
I 4un 35 in the front 40 in the rear, when I go play I go right to 18 pounds of pressure. Off road, with your CDL, the front and rear tires have to be at the same pressure to prevent damage to the drive line.

 

Yes, I know for off road only. That makes sense to keep the pressures equal when running with the CDL. I'm thinking about getting the "Original" Staun deflators (6-30 psi range), which are conveniently preset at 18 psi. Thanks Mike.

Is there another good story from Spike555 on how to deflate tires?

 

Those are the deflators I have used for 5 years now.

 

The only story I have is about one of my trk tires exploding on the expressway.

 

AH! Wish this thread would have come before my trip. I ran at 22 front and 28 rear for 3 hours over washboard and sand. Everything went well, but good to know to keep them at the same, and go lower.

 

Depending on the tires you have and they type of off roading you do, will determine the proper air pressure, 18 inch tires can't safely be aired down the way a 16" can, with out cut the side walls out of them.
