I'm running 56 on the front, 64 on the rear.

We started with 80 all round but I think that's a pretty stupid bit of guidance.

I'm thinking similar Jean, I never liked Pogo sticks.

50/80 so far seems OK but we've only done 13 miles, I'll let you know once I've been further!

If you're running at 80 for any length of time I'd suggest you apply some more adhesives to your 'barnet' and false teeth to keep them from falling off or rattling.

Very few Motorhome tyres require that much pressure and the ride will probably be harsh, at the very least, and anything that can rattle will rattle despite the best efforts to wrap everything in cotton wool.

We've run our 7m Pilote MH (3500kg) for the last seven years with the front 47psi (3.2bar) and rear 61psi (4.2bar) - no problems, a decent ride and minimal crockery rattles.

And here's proof of it speeding in France in 2019 -

Not worried about my barnet, not had any hair there for about 14 years. As for crockery rattles, we have some cushions we stuff in the crocks and pots and pans cupboards, they do a very good job of dampening rattling noises.



The thing is, it's fitted with tyre pressure sensors so if I drop the pressure the damned warning lights will come on!


We've got some decent runs coming up soon to properly try it out.

Possibly but before I did that I'd want to investigate the impact upon the insurance...

I looked into this years ago and following advice from Continental (you only have to check the correct tyre info sheet to get the right pressure as they have done all the testing so why not believe what they print) have been running my 3.7 laden Rapido at 52 psi Front & 55 psi Rear for several years and have not had any problems with ride comfort or road noise (both much better).

Actually running at a high pressure does not allow for the correct footprint of tyre on the road surface so aquaplaning could be a factor as the tyre cannot remove as much water as well as braking footprint is less so stopping distance is extended.

When I first had the van it always seemed I was driving on tiptoes and it was very light on steering too.

I use TyrePal which shows me exactly what the tyres are doing so you can decide if things are not right at the pressures you are running at.

However each to there own. You must do right for you.

I've never bothered with the pressures on the car, if it looks right, it probably is, but the vans ride is very harsh, the front is better, I suppose due to coil spring but vans still have cart springs on the back, we've had two vans with air assist, but I'm not sure what the intension is, but they didn't seem much different with the recommended 1.5 bar in them.

I think Air Assist is mainly to stop body roll. Alco chassis vans have independent suspension. Thought cart springs went out with Wells Fargo
