Use at your own risk.
I've always believed that no matter what it is that you are doing,
theres always an easier way.
For me, that means making my ride or job easier.
Here's a little secret to making a bad thing feel not as bad.
Air pressure is the key to success in anything with air filled tires.
For some reason, anytime I get on a rubber tired tractor it always rides like crap.
It bounces, spins tires easily and by the end of the day my back is wrecked.
I've learned over the years that too much tire pressure can be just as bad as not having enough tire pressure.
One of the first things I do when running a rubber tired machine is first, show up early.
It takes about a 1/2 hr to get a machine aired down to the point that makes me comfortable.
A comfortable operator is a productive operator.

Showing up early also lets me do this without people asking stupid questions.
The 613 I ran calls for about 44 psi in the fronts.
I know from experience that who ever airs up our tires has never run that tractor after he's over inflated it.
Checking the fronts showed both at 60 psi.
Not with me in the seat.
In a few minutes they were both at 35 psi cold.
After the tires warm up a bit, the pressure climbed to 40 psi.
I happen to be the kind of person who likes taking chances.
I'll always try something new to see if it makes my life easier and more productive.
That said, if it can go wrong... it will.
So before you go turning wrenches and changing things around, be prepared!
It would look really bad if you got a flat because you lost a the valve core.
It might even get you fired.
So, please have the right parts and tools before you go trying something like this.
On loaders, I'll grab a full bucket of dirt then air down until I get nice bulge in the side wall.
A gauge, extra valve cores and a compressor is a must!
My Cat Performance Handbook has all of the correct pressures listed in it.
I like to go about 10 psi below for more traction and a better ride.
