I have a 80 Series with full time 4WD. I try to keep my tyre pressure even at all 4 as best as I can to reduce drive line wear.
When fully loaded (off roading), I the rear half of the car sitting lower then the front, due to the weight in the back. This can be leveled by having more PSI in the rear tyres compared to the front. Additionally, at times I travel on on-road to get to and from locations, fuel up, etc., and I'd like to avoid airing up to full road pressures during these short periods (distances of ~50kms on-road driving).
Will driving on on-road with mixed tyre pressures result in wear to the drive in this situation? I image when fully load, and with the rear sitting lower then the front, there rolling diameter of the tyres would be different anyway, and could having higher pressure in the rear possibility reduce drive line wear?
