tyre pressures

Post by Barno111 »

G'day guys i have just perchased a set of MTZ 285x75x16, as you guys would have read i was tossing up between the mtz and the dueler MT. Anyway what tyre pressure do you guys run around town? Im only use to running AT's so im not to sure on the muddies pressure. Help shred some light on the situation and tell me what pressures you's run around town.
cheers fellas

Depends on what your 75 is doing.

Ive got 265/75's on the work truck that run 48psi front/75psi rear, but thats a drill rig.

On the lux in 31x10.5x15 im running 35psi and thinking of dropping it down to about 32psi as its a bit rough unladen.

Hey Barno..
In case you are un-aware, there is a 'Rule of thumb' that from stone cold to operating temperature your tyre pressure should increase by 4 psi. If it increases more than this then you're running them too low, and if less than 4 then you're running them too high.
There is a bit of trial and error involved but try starting with them at 32 cold and see how you go.

I've got 305 MTZ's and run 36 front, 38 rear on the road. That's on a GU wagon.

Any higher on the front I found the steering "skittish" at highway speeds.

Any higher on the rear and the vehicle wanted to tango when I hit a pothole, rough surface, etc at highway speeds. 38psi seems to soften the bumps just enough.

I have the same size on my GU I run them at 36 around town and drop them to 30 off road and the rougher it gets the lower they go, I didn't do this with the first set and they got damaged, now I let the down every time and they are going really well no damage so far and wear has improved.
