Checking Motorhome tyre pressure

[Nickorchard]

Hello
We recently bought an Auto-trail EK 590
I wanted to check the tyre pressures which need to be 75 PSI

Took it to local garage and the supermarket garage however the compressor max pressure was 60 PSI

Where do people take Moto homes to check tyre pressures or do I need to get my own compressor?

Cheers

Nick

Well pouring with rain here near Niort…should be in Spain in a few days where hopefully temperatures will be nearer Death Valley temps. Will put in 76psi on rear for now. That’ll do

Maybe related. A soft tyre will warm up quickly due to the extra movement generating heat.

Probably more to do with Michelin accepting that the front axle is unlikely to be as close to the load capacity as the rear on a motorhome CP tyre so they can nibble at the safety margin.

Still don’t really know what pressure to put in. On the tyre it says 113 at 80psi (which is 2300kg across the axle)….I looked it up. If I was running at 2300kg on the rear axle I would put in 80psi when cold. Surely when I start driving the pressure would go over 80psi because of friction and the tyre is max psi of 80.

I don’t run at 2300kg I run at 2180. Each 4psi equates to 100kg across axle so presumably I should put in 76psi or even 75psi which would give me a bit of leeway for
friction heat and ambient temperature.

I’m in France now, soon Spain…not sure where I could get Trye Pals from.

Your still thinking too hard, just put in 75psi and check after 30 minutes driving, that should put your mind at ease, As for TyrePal, if you know where you will be stopping in the next three days, then order on Amazon and put a pick up point at your destination. good luck and travel safe.

HaHa…no patience ….STILL no one has told me what pressure to put in a trye when running at 2180kg on rear axle….is it because no one really knows !

You keep being told, but you are not listening

My new Conti All Seasons are running at 72F/75R and nothing has lit up on my dash. I may drop them another couple of psi when it's warmer. Lower pressures usually mean a slight increase in fuel consumption because of the greater rolling resistance. Dental checkup on fillings due in May.

Hi All,

really interesting reading. I have purchased vonhaus inflator due to your recommendations, it works great.

looking at tyre pressures, I think I have settled on 70 psi on the rears and 62psi on the fronts, based on 2000kgs rear axle and 1700kg front axle. Have weighed this at public weigh-bridge…

this is for Agilis CP tyres. although Michelin suggest higher pressures, such as 80psi for rears….

i do agree with their suggestion to ensure pressure whilst vehicle standing with less usage…

Interesting read, so "Bibendum" says 80psi, well looking at the shape of him I will stick with being slightly under, inflated.

Yep sounds good…totally agree. It’s 4psi per 100kg across axle so 80psi for 2300kg (that’s the official figures for 113) therefore 2000kg is 68psi…(80 - 3 x 4) for Lenny HB and Peregrinator as they seem a bit confused and irritable )) so 70psi gives 2psi leeway….perfect….WHATEVER TEMPERATURE !

Hymer tyre pressure
4.5= 65psi
4.8 = 70psi
5.0 72psi
6.00 87psi

5.5 = 80 2300kg
5.25 = 76 2200kg

4.75 = 69
66 front 4.5 *
76 back 5.25 *

I currently run my rears at 70psi, I will try it up to 78psi which I calculate it should be, Michelin campers at 2250kg max and see if my fillings stay in. Any increase in mpg can only be welcome.
60psi should be adequate at the front but might try michelins recommendations of 65psi and see how that works.

Yep again I agree…78psi rear 65psi front….

Just out of interest, for the John Deers tyres…..9psi in the rears…..

No confusion what so ever for my vehicle, Tyre Manufacture says 80psi, Motorhome Manufacture says 80psi, why are YOU so confused? nothing to be confused about.

I take back the word confused
