Motorhome Tyres

[Moss]

I know this has been spoken about many times, but I still find it a complete minefield. Like many others I have inherited MIchelin Agilis camper tyres that feel like your running on square wheels. They are due to be replaced and I want to get an set of reliable good value for money tyres that don't have to be inflated to 80 psi. My MH is a Swift plated 3750 kg with axle weights of 1850 front and 2000 rear. I have been considering Continental VanContact A/S Ultra 225/75 R16 10PR my current tyres are 225/75 R16 CP 116 are these a suitable replacement? Im just worried about the axle weights.

225/75 R16C 121/120R 10PR​

Hi,
What was the reason for changing to tyres “a size up”?
Is there a benefit I’m not aware of?
Thanks

I changed up a size to get a higher load rating, from 109 to 112 so I could up rate the axles load.
The side benefits were a better ride quality and a more accurate speedo reading.

What size did you go from and to?

As stated before there are various sorts of "Cross Climates... and lots of confusion.
Cross Climate (in various upgraded forms) for cars...
Cross Climate Agilis which are the commercial van variant and are all season tyres..
Then we have Cross Climate Camper tyres for motorhomes..

I run vanco continentals in the back and i put on Avon as12 all season 3pmsf rated.

I run nothing like 80 psi, I run around 70 back and 65 front.

Much more comfortable and the avons were ace on our ski trip to italy a couple of weeks ago. When all went for chains we cruised through.

Shortly after i bought them, i read that Avon wont warranty them for motorhome use. I have no idea why, all the weights check out, they are reinforced side walls, the correct ply and even suitable for vans over 5.5 ton?

So i have no issue with using them, my van is on its levels when parked, it weighs less than others.

Thanks

On our VW the larger size can be run at a lower pressure, there is a tyre pressure sticker inside the door.

I realise most motorhomes won't have this though.

Is that Crossclimate Camping tyres or Agilis CrossClimate normal van tyres. They are different things.

Crossclimate camping, definitely a better ride and cornering feels more precise

Why running at 80psi seems a tad high?

Thank you for contacting Michelin customer care.



Regarding your query, the recommended tyre pressure for the rear (single) axle of a motorhome running on the MICHELIN Agilis Camping is 80 PSI (5,5bar) and for twin axle 69PSI (4,75bar)



This is due to the construction of the tyre with 2 casing plies enabling the use of higher pressures. Its construction and the use of higher pressures is designed to cope with continual heavy loads sometimes found on motorhomes and can help with wear pattern issues, if lower pressures are used particularly on the rear axle.



The front tyres however can be adjusted down to a pressure of 65 PSI for a more comfortable ride and optimum performance.



Here are some safety points to be taken into account when it comes to tyre pressures:



1. Always check the pressures when the vehicle tyres are cold. We consider the tyres as being cold if they haven’t been used for at least 2 hours of it they have rolled less than 3 miles at low speed. If the tyres are not under these conditions they are considered to be hot.

2. When the tyres are hot you should always add 4,4 PSI to the recommended pressure.

3. Please remember - Never deflate a hot tyre!



I hope this information was helpful and please do not hesitate to contact us again if you have any further questions. We are happy to help.

This is exactly why I have nothing to do with Michelin and their CP tyres.
No mention of tyre size, total weight or axle weight. It could be a small van conversion or an enormous extremely heavy motorhome, same advice every time.

When I contacted Continental about the VanCoFourSeason 2 I was looking at they emailed me a chart with pressures vs axle weight for the specific tyre I was looking at. Very helpful
