swift conqueror tyre pressures

[ollycaravanmad]

i have just bought a 1997 swift conqueror 640 salon Twin axle. I just wondered if any one knew what the tyre pressures are meant to be according to the owners manual.

If any one has a owners manual going spare or if someone could email me a copy that would be great

Thanks for your help

Happy caravanning

Hi Olly,

This is a common problem. If you cannot obtain a handbook the following formula may be useful.

A = Maximum loaded weight of caravan (there should be a plate on the 'van stating this figure).(Say 1300kg)

B = Maximum tyre pressure (stamped on tyre catcass) (Say 73psi)

C= Maximum load of tyre (stamped on tyre carcass)(Say 900kgs)

D = Number of wheels. (Say 2)

Multiply A - by B divided by C - then divide the result by D = this is the approximate tyre pressure.

i.e. :- 1311 x 73/900 = 106.3 divide this by number of wheels (2) = 53.2psi.

The figures above are based on my caravan, the handbook of which states tyre pressures are 54psi.

It sounds a bit complicated but is reasonably accurate if you have no other option.

Sorry Olly,

Just realised your caravan is a twin axle - the above is for single axles only.

Another senior moment I'm afraid!

Swift have their own forum run by their employees which is called Swift Talk

I have an idea that you can buy manuals but either way they will be able to answer your question Olly.

Olly an addition to what has allready been said. your caravan should have had a tyre change due to its age,check that the tyres now fitted are less tan 5 years old & are the same size & specification as the originals as this could alter the tyre pressures reqired from the original pressures
