tyre pressures on road

hi team
i must admit this is a great forum
heaps of knowlage out there
thanks heaps for all the feed back
startin to feel part of the fam

That's what we like to hear

Bugger now Im getting confused with the tyre pressures, na not really I had two B/Stones Duellers fitted on the back and the fitted assured me that 36 was the best for around town, I know if i put more in them when the wagon is empty its like ridding a bull, Im just waiting for the 8 second bell to ring so I can get out. But I pump them up to 40 when its loaded up and we are off on the black trail.

I had about 35psi in my Duellers, but they were still bulging a bit so have gone up to 40psi this week. Will see if that improves economy. Seems to ride ok still.

I had my stock standard tyres up to 48psi and got an extra 2L/100km, standard setting was 37psi.

This is true in many vehicles.

so do we just go by look and feel then ? is the 4 PSI rule still the norm? and what was the 6PSI allowed for 4x4?

I run mine at 45psi

i run my bighorns at 40psi and was thinking of going back to 38psi as they seem to hard just running about town

roofy

I run mine at manufactureres specs initially and adjust accordingly... no maker is going to tell you pressures that chew thru his tyres deliberately.. he'll be out of business in a year.

You also cannot just compare tyre pressures... there will be anything up to 15 maybe 20 PSI difference between LT and Passenger tyres, ply's, rim width, suspension etc and so some people here will be quoting apples and others oranges... some will have utes with an ally tray that skitter everywhere at 38 PSI others will have Telstra cabs with a heap of gear that need 48 PSI

The sidewall presure is also meaningless as other than a max inflation figure which is the sole reason that it is there. Remember the bloke who made the LT tyre designed and constructed it to go on Light Trucks, thats any Truck/4WD/Vehicle single/dual wheel etc etc NOT Nissan Patrols in particular... sama sama Passenger constructs.

Given a specific tyre manufacturer, type, size, rims and identical vehicle...Some people will run at say 36 PSI looking for comfort and another will choose say 44 PSI in search of that last bit of fuel economy they can get and bugger the teeth rattle.
