Recently brought a Wellhouse conversation, loving it and getting ready for the spring. What tyre pressure should I be operating on?

it should be on your drivers door. set to max load value.

Ive only got one measurement which for the tyre size is 2.3 BAR (34 PSI) - this seems rather low given the add'l load factor for conversion ?

 

Many thanks

I agree with Monster S. 

 

However, it may be worth asking Wellhouse what the weight of their conversion is.

 

You don't say whether you have a rear or side conversion.

 

I will be removing my two rearmost seats to have a rear conversion.

 

I guess the original tyre pressures are calculated on the assumption there may be two person sitting in those seats (and the middle seats for that matter).

Most Alphards weigh two tonnes, or so.

 

What is the weight of two average weight Japanese passengers ???

 

Or 2 Sumo wrestlers 😲

For my side conversion from Calder Campers, the recommendation is 34 PSI , front and rear.

Hi TreforL,

 

I recall seeing a post on this forum stating 38-40psi generally, and when we bought from Wellhouse they suggested 38psi both front & rear for their side conversion. However, we did an LPG conversion after and added a towbar for bikes - so the weight distribution changed and we needed to re-calculate our tyre pressures. Ultimately, the pressure depends on tyre manufacturer and load for each axle (front and rear): see Martin1621 - Other Tyre Pressures

Just brought back my Alph for its annual service from Calder Campers - head technician has stated :-

 

Front 32

Rear 37

 

Side conversion

I've just recently joined and trawling through various threads.

RE. tyre pressures on converted vans - I take the vehicle for a run of approx 20 miles on straight(ish) roads, stop and measure the tyre temperature across the tread, the palm of your hand is pretty sensitive. If the centre of the tyre is hotter than the sides then the pressure is too high and vice versa. I hope this helps
