I run my 16inch Q78s at 40PSI on the road.

I ran 14 usually with internal beadlocks then lower if required.
Just be careful with them on 8'' rims. They would suit 7'' or even 6.5''.
Groove the centre lug too.
Cheers
Dave.

When on the hilux I run them at 25 or 30 psi on the road. Just depends how long I want to wait for them to air up.
Off road I drop them to 10psi and play with them from there.
When on my 80 I run them at 30 on the road.
I have driven 200 ks (each way) straight down the hume freeway at 110kms under each rig and its all sweet. I have found if they are to high psi on the road they drive really bad.

On my g wagen - 2500kg, beadlocked 15X7's, 30PSI on road, 8-12PSI off road, but I ran as low as 5psi when necessary, but lateral stability was poor at 5 psi.
