Tyre pressures

[ozieagle]

I have recently bought a Hi Ace camper van. Went to check tyre pressures, and the manual states 47psi in the front, I'm OK with that, but the rears are specified as 65 psi. Maybe this is for a fully laden vehicle, but seems a bit high for a camper van. There is no loaded and unloaded info.

Any insights?

Thanks

If they are [ LT ] light truck, you will kill them running them under inflated

Yes they are LT tyres.

Consider the weight distribution of a camper van, nearly empty at the back, with the weight of the engine, passengers at the front and very little at the back.  I would expect that the rears would not need 65 psi, as there will never be a 1/2 - 1 ton load in there. As is my compressor was struggling to get to 60 psi, a small diaphragm type.

I know about under inflation, and about over inflation.

Totally understand where you are coming from, In my little workmate I run 42psi front and 36-37psi rear ( unladen ) Tyres last nearly 90,00km and wear beautiful. They rely on pressure to support the stiff sidewall
