Tire PSI

[BEnglish]

I run my fronts and rears at 70psi, non towing.



fronts at 70psi, rear at 80psi when towing.



I don't deflate the rears very much when not towing because its takes forever to get them back up to 80psi even with my industrial air compressor.

Here is a good answer to raising and lowering tire pressure easily. In off roading we use co2 to reseat tire beads and run pneumatic tools and air up tires. They sell very expensive aluminum setups with all you need, but for a quarter of that cost you can build your own. Just search around and get a co2 regulator and rent/buy a ten lb. bottle from the local welding suppliers, where you can also get the curly hose and whatever other fittings you need. You could probably also get the regulator from them, but I searched around and got a used one real cheap. They are super fast at filling tires and because the co2 molecules are larger they don’t seep out. And they have less tendency to change size because of temperature. Its just better to run and cheap to fill the bottle. I pay about 8 bucks for a 10# bottle and 5 bucks for a 5# bottle.

I run 85 lbs front and rear solo, but that's because I have 19. 5" wheels and 245 x 70 Hankook tires. The tires are commercial with 4-ply tread and 1-ply sidewalls. The wheel/tire/air pressure combination makes for a great ride and tremendous handling. Much better than OEM. There is more wear in the center of the tread, which means I could back off the pressure and probably improve everything except fuel mileage. But I sure like what I have now.

Did you notice an increase in mpg after the big wheel install?
