tyre pressure

I run 35. Any higher and I find the 80k wobble gets worse

40 here. Use to run 35 but the fronts scallop out to quick..

Running such low pressures are so the ride seems smooth but what happens is the tyres wear too quickly and they generate more heat shorting there life.

My little 2lt car can run 32psi but a 3t rig should run much higher

I tow a lot so 42 psi for me but if I did not then 40psi would do but 35 psi and below is ridiculous...........

Love to hear the reasoning others have for running low pressures???

Hi BA - agree - I run them at 38-40 cold. 42 laden. Only time I run them low is mud, sand, traction reasons.

WOW you guys run high pressures, I'll run 40psi for hwy duties and 35 psi around town, and down to 16 psi off road

Hi threedogs. I just based mine on what the dealer recommended - when I put the Mickey Thompsons on he recommended no lower than 38 on the black top - for all other surfaces was play it by ear. Also recommended 2-4 PSI increase for loads.

Google the 4psi rule for tyres. It basically explains that if you get a larger increase in pressure of 4psi after driving for a period then your pressures are to low etc etc. Its a little bit consuming to start with but once you have it sussed its all good. I dont run anything under 38psi.

You Guys definately run higher than me

200(29) Front and 250(36) Rear

No abnormal wear and a Good ride

Interestingly the tyre pressure placard on the 2012 GU 8 recommends 28 front and rear (30 if loaded on rear).

Go by tyre manufacture not car manufacture.. they want it to seem comfortable... 29psi is just way to low for a 3t car... also what gauge do you lot use.

Most petrol station gauges are out by a fair bit, I have an expensive gauge I got for racing and if using a petrol station I always check it and find some gauges can be out by as much as 10psi .

My tyre inflator gauge is out by 5psi and it cost $60.
