air compressor for inflating tires

The on board compressor on a diesel pusher WILL NOT work for more than 100 PSI easily. Most mid to heavy weight diesel pushers call for 120-125 PSI in the front tires. Being low on air 20-25 PSI is very significant, as most times the two front tires are at their maximum weight capacity with full air PSI in the tire.


We have many discussions on this site about how a toad brake system may net you two extra feet stopping distance on these big mid to heavyweight Diesels making you "safer" :R, but for any fellow diesel pusher owners, PLEASE put that 120-125 PSI in your front tires. If your Front Tire blows out due to being underinflated or overloaded at 70 MPH, you most likely screwed and there will probably be a REAL safety issue!

But the the on board compressor will if you know how to work it! Lots of RVers and over the road truck drivers use the engine's air compressor for airing up tires and even to operate air tools. But the engine has to be operating at higher RPM to gain the necessary air pressure. And we have tire air gauges to insure proper air pressure in tires.
