Thread: TYRE PRESSURE

Ive been running 55 psi all round on my 130 PUMA...........I feel it rides well at this pressure and comfy (but im coming from a 1999 cruiser ute which near killed me comfort wise).

Maybe I should not be running 55psi ??

Many moons ago when I worked in the tyre industry, this question came up many times. One of the old guys that had been around for ages showed me a little trick.
For normal road use only.
Park the vehicle on a flat surface, preferably concrete. Cover one section of the tyre with a wax type chalk. Say two to three inches wide (More doesn’t matter) and roll the vehicle in one direction so that a ‘chalk’ imprint is left on the concrete. If the tread pattern is more pronounce on the outside of the imprint, the tyres are under inflated. If its more pronounce in the middle their over inflated. You’re looking for an even thread imprint across the width of the tyre. As your vehicle load changes so will your tyre pressure requirements.
I used this method several times setting up tyre pressures for modified road cars. It does work but it is time consuming.

No big deal Lionel. I have made the same mistake myself.
