Tire Pressure

Start carrying some tools with you when you get back home. Screw drivers, wrenches, pliers, socket set, hammer for banging in stubborn sliding tandem pins in when they're stuck. Those few things will go a long way for you in case you need them for minor repairs like putting on a missing mudflap, taking light covers off to fix a broken light, etc.. Oh and don't forget a 5th wheel pulling arm so you don't have to worry about getting all that grease all over you and can even help with installing tire chains during the snow!

 

@uncleal13 is correct about tire pressures. I run 120 on all my tires. All my tires wear perfectly even.

When a tire flexes, it builds heat. Heat causes blowouts. A semi tire can take upwards of 400psi before blowing, but 250 deg temps willl make it explode. Running a higher psi reduces flex and allows the tires to run cooler. All my tires are at 120psi cold. In the Tx heat, afted running loaded, my tires will only have expanded to about 130psi. I dont have any current temps because I lost my temp gun over a year ago and haven't replaced it.

But I invite anyone to run your tires at 100psi and check the temps after running all day loaded. Then air them up to 115-120psi and do the same thing. You'll see the temp swing from cold to hot is larger with less psi. And more than likely the tire will be hotter with less psi.

 

Im just gonna say this. When yoh use that, remember to SET YOUR TRACTOR BRAKES. Because you have to release your trailer brakes for it to work.

Yes, I carry a glad hand air hose, no I have never had the truck start to roll away.

Edit: Brain fart. I fixed it

 

Sure you didn't get it backwards there? Set the tractor brakes (pull out) and release the trailer brakes (push in). Since it runs off your glad hand air is (or should be) supplied only when trailer brakes are released.

 

You connected to the red line on the truck and not on the trailer, right?

 

You caught me before my edit lol.
