Keepin Cool

Google gases in air!
Air is 78.08% Nitrogen, and 20.95% Oxygen.
Proper tire maintenance you should check the pressure every month, adding when it is cold, and removing when the ambient temperature is higher. Pressure should be checked in the morning out of the sun, on a unit that has not been used for at least 4 hours. You also should have a depth gauge, to measure the tires middle and outside. If you have more wear in the middle and less on the outside, you may want to lower the pressure a few pounds.
An infrared temp gun is also a good idea. The More you weigh and the faster you go has a lot to say about the heat build up in a tire

 

Not sure on cooling other than nitrogen, but as far as extending the life proper inflation as was stated before is key and there is a product on the market called Centramatic Wheel Balancers you might want to checkout. Supposed to control ride and vibration which in turn should lead to cooler temps and longer tread life in theory.

 

If you try , let me know what you think. I'm curious about the product but my money is tied up right now in trailer side skirts.

 

That info is from cross-ply times, not valid if talking about radials.

 

Yes it does the tire still flexes the same, if you have a heavy load the tire tread will cup. I worked with a tire man and he could tell you, the exact tire pressures for trucks, and trailers, that ran designated loads. It works especially well on front tires, p&d especially.

 

when a radial tire is low on pressure--the center area of tread will centrfically (sp) forced farther out as the tire rotates--therefore wearing more on the center of tire than the outer treads

 

I always run max pressure or 15% over pressure on all tyres and they wear evenly.

Free rolling tyres (radials) wear from the outer edge, drive tyres from center, there's nothing you can do to it.

 

Slow down when your loaded. I can tell how many trucks I have seen running loaded to the max running 75+ in 100 degree heat. I usually see them in a rest area waiting on a tire truck.

 

No! No! you have that all wrong,they were just taking their 10 hr break. Just kidding,i agree with you on the slowin down in hot weather.

 

possibly try a less agressive tread, or harder compound. Assuming the tighter tread blocks would have less deflection, less friction and therefor less heat. doubt it would be enough to notice though. If your having problems with a blowouts i would try a different retreader, make sure your getting good casings, cause if the virgin casing was run low, it's not gonna last.
