could any one tell me a decent tyre pressures,for a syncro tin top camper,quiet alot of road use,215/70/16 all terrains thanks

somewhere between 30-42 psi should be ok,cj.

Coincidentally, I asked the same question at my independent VW garage yesterday and was told 40psi at the front and 50 at the rear. Who's right?

This is for slightly larger tyres than standard.

I run something like 38psi all round for road use on 235/75-15 Mud Terrains.

VW says 26psi front and 30psi rear for 205 R 16 on 5.5J rims. Sounds low, but seems to work. I have done about 5000 miles on those pressures and the tyres seem to be wearing flat, indicating correct pressure. I may be wrong, but the tyre pressure is correlated between air capacity of tyre, and weight. Therefore my little brain says that a bigger tyre will mean lower pressure. I would start at 26F, 30R, see how it goes. Drive the same bit of road, near a garage with inflator, and vary the pressure till it feels right.

Just consulted my Haynes manual for '82-90 Transporters that lists five tyre sizes:
175 R 14 C: 41psi (front)/48psi(rear
185 R 14 C: 38/55
185 SR 14 Reinforced: 33/42
185 SR 14 C 6PR: 39/48
205/70 R 14: 30/36.
Hope that's clear (as mud!).

The other way is to calculate the pressures from the max axle weight and the tyre max load at max pressure weight...
divide the tyre max psi by the tyre max kgs and then times it by the axle kgs.. (think thats right..)

i've got 3 newish 235/75/15's BF AT's on mine, max psi is 50 on them

the spare I have on o/s/f, also a BF AT 235/75/15, but an older design, has a max psi of 40!

god knows . . . .

oh dear Andy... whats the max load at the max pressure for those then?
