T/P

Does anyone know why the front tires are supposed to be only 25 p.s.i. ?

The NDT will survive at many different pressures. Load ranges of the tires I am sure was considered when they set it at 25. But, 25 is also about the lowest you can go without the shoulder of the tread starting to really scuff on pavement.

Lower is better for these trucks because the tires basically are your suspension when it comes to comfort, the lower pressure gives you better traction off road and still allows for non mushy control on pavement.

Remember, these trucks were designed to carry 1-1/4 of stuff off road and on road at speeds no greater than 45 mph. So, like everything else, it is a compromise. If you are going to be just highway, push it up to 30 or so and your tires will live longer. If just in the dirt, lower them to 12-15 and enjoy the increased traction and comfort.

As I sanded my truck, I found several conflicting things regarding tire pressure:

The dash just said "Tire pressure: 25" stenciled on the glovebox door.

The rear bed pockets had both "T.P. 45" & "T.P. 25"

The front fender had "T.P. 25" and what looked like 35 (?) as well.

Not sure what was going on there, other than different tires over the years maybe?

The manual specifies 45 rear 25 front. This is the only M.V. that I have ever seen that uses a different pressure on the front tires. I have always been unwilling to run mine at that pressure I always used 45 all around, maybe i'll try it to see how it handles.

I had a 78 Chevy C20 service truck that listed 35 and 60 PSI for the front and rear respectively on the door label. I always ran them at 55 all around and rotated regularly. Never had a problem. At 35 up front with the factory 454 in there, they always looked squishy and low.

Most 1/4 jeeps were TP 20 and TP 25.
