tyre pressures

[big john wayne]

Anyone know what my tyre pressures should be ???

Its a single axle ( two wheeled ) Adria Optima 4 berth from about 1992 ???

Where a manufacturer's recommended tyre pressure is not available, this formula will allow you to calculate the approximate tyre pressure for your caravan.

(MTPLM Kg) x (Max tyre pressure in psi)/((Max tyre load Kg) x (Number of wheels)) = Running tyre pressure in psi

Example:

Single axle so 2 tyres

Max tyre press = 65psi (written on the tyre wall)

Max tyre load = 600Kg (written on the tyre wall)

MTPLM = 950 Kg (see plate on caravan chassis)

950kg x (65psi/(600kg x 2)) = 51.46psi

Anyone else ????

I'd just repeat the information given by Legsmania.

Given the age of the caravan I'd trust that method better than secondhand or anecdotal information.

 

[big john wayne]

so whatr you sayin 40 or neere 50 ??

What's the gross weight of the caravan?

The tyres will have the maximum load and maximum pressures moulded on the sidewall.
