What tyre pressures are you running ?

[kdalton]

tyres are 235/75r 15.tyre pressure 36psi

[SierraDan]

Drop to 22psi.

[kdalton]

isn't that a bit low.the tyre max pressure is 41psi so it sais on the tyre.im driving on the road mostly.and the beach 40percent thanks

[Red89]

Not for a light wieght Sierra, most guys run low to mid 20's on road. It wont get rid of the problem but will definitely reduce it and is the easiest thing to do first and is a very common mistake new owners make

[Gwagensteve]

Have a look at the maximum load rating of the tyre. I bet it's more than the whole car weighs. That's why you don't need 41psi in the tyre.

[BertZook]

not sure if sierras has a tyre placard but in the jimmy, the recommended pressure is 23-26

[Gwagensteve]

20 psi for a Sierra. And that's with a tyre with a very low load rating

[kdalton]

max load rating is 1000kg.is that load rating for one tyre or 4 tyres put together.

[got_bar_work]

That will be for one tire

[Gwagensteve]

X2. That's one tyre.

[got_bar_work]

22 psi on road should be about right
5-10psi off road

[kdalton]

god im a wan__r. my hilux tyres are max load of 1030kg and the car .weighs nearly 3000kg.so I will let them down to 25psi and try that.thanks for all your help guys and girls.

[kdalton]

went for a drive in some soft sand down the beach.put car in low range and the sierra just cruised through it.in the hilux it would of been totally different.so if I drop the tyre pressure its going to be even easyer. starting to like the sierra cheers
