Tyre pressures on road - Dual cab diesel

[9W6VX]

The placard on the door states tyre pressure for front and rear is 29 psi all round.

My original Bridgestone HT840 highway terrain tyres 255/70R15 which is 29 inches in overall diameter is about 85% worn and I've got about 31,000 kms out of it.

One thing that I have noticed on many Hiluxes over here is that the front tyres do not have even tread wear. Almost all have excessive tread wear on the outer edge.

I think the tyre pressure is too low at 29psi for the front and I'm running at 33 psi cold now in order to try to get even tread wear.

I normally check tyre pressures at home after the Hilux has been unmoved for 3 to 4 hours.

What tyre pressures do you guys run on road?

Thanks troyco and oldrev.

It's 6am in the morning over here and 8am in the Eastern part of Australia.

Going to do about 250 kms of driving today and will be back tomorrow evening.

Regards and have a good day mates.

:evil:

interesting, i have always thought the tyre pressure seams incredibly low.

slightly bigger tyres on my old vehicle where 45psi.

i think the biggest thing with uneven wear on the front is the IFS, since the wheels wheel be naturly pushed down on an angle

I run 40 front and 44 rear...when I'm carrying a load... I am sitting at 2750kgs fully loaded... empty. i run 40 all round... as I'm still pretty heavy unloaded... I get very even tyre wear on my 31 STTs... Cheers TOMUCH..

Brendon,
We have to educate you better in the use of Australian slang:
As you know, a Mate is a friend and while it is always acceptable to call another male 'Mate' directly to him, usually the plural term 'Mates' is not used as you do above "good day Mates"

However when referring to a group of friends to a third party, it is ok to refer to them as mates.

I hope I havn't confused you mate.

If I have, just relax La !

OK, now that is my Malaysian Slang - how did I go?

Rich.

PS a more appropriate way to refer to us is 'Guys' or 'Fellas'.

AKA the 'matsalie' (how do you spell it?)

At my last service (10k km) the bloke told me to run the standard tyres at no less than 36 PSI.

Hope that helps

I run my ATR Coopers at 35psi all round on road.. even wear for me..

[Doug67]

Running 40 psi on 31's is not enough with a bit of a load, noticed less wear in the middle of the tyre. 33" 40 psi seems ok wiyh a bit of a load so far with 17k on them. I go down to about 18psi in the bush and 13psi on the beach.

Many thanks for all the replies.

Seems that many here run tyres pressures much higher than the standard.

I agree with that.

Rich,

Over here in Sabah, we don't use 'lah'.

We use 'bah' instead and it is unique only to Sabah.

The spelling for caucasian is mat salleh in Bahasa Malaysia.

Got it? I hope I haven't confused you too.

I run BFG's.

I run them at 35psi (unloaded) and 40 loaded.

I hope this helps.

Using BFG AT's 225/16" I find 32 - 34 unloaded great for the SR5. Anymore tends to make the tyres "chop" on a funny angle and less eats the sides. One thing worth noting though, the front left seems to chew heaps more than any of the other tyres. I tend to find the SR5 has a general understeer tendancy and seems to bite into the front after the apex of the corner. Mind you, it handles well and most likely corners/roundabouts should be taken with less speed...
