TYRES

Recommended Posts

I know this has been covered many times before but what tyres best for MH.

 

Just had mot and all 4 tyres have failed , not because they are worn out but the fitter has found

 

small dents in the side walls, no cracks plenty of tread left.

 

The tyres are just 4 years old and are Michelin Agilis Camping.

 

Has anybody fitted Hankook if so what did they think of them.

Not an answer to your question. BUt we always cover our wheels when in the Spain/sun. Use the check shopping bags bought in (Pound" shops just split them up the back and then they will go over the wheels . They last for 1/2 seasons, but at a couple of pounds or euros, save on tyres.

We also had to buy 4 new tyres this year for the MOT . I guess due to the weight of MH they don't last as long as car tyres We bought 4 michelin

Mr Ford supplied my Transit PVC with Hankooks. They've done 35 000 miles of quite fast driving and probably have 5000 left before I replace them. The van goes around corners and stops OK, the ride is fine and they haven't gone pop so I'm happy with them.

At 4 years I would have a word with Michelin for an inspection then a reasonable contribution!!

I have always used Agilis campers and change at 5 years (more or less!!)

 

As this wouldn't hurt to ask, I vaguely recall a problem like this coming up before

Update this morning I went to local tyre dealer , he said there was nothing wrong with

 

the tyres. The small dent as he called it is part of the manufacture where walls are joined together.

 

I have just spoken to customer service at Michelin and they have confirmed there is nothing to worry

 

about and that it is indeed part of the manufacture.

 

So it,s now back to the MOT place to put them right

It is quite common to see dimples and dents in commercial vehicle tyres that are formed during the construction of the tyre.

 

You say the tyres are 4 years old, is that the time you have owned the van or is that the manufactures date for when the chassis was built, don't forget that motorhome chassis can be standing around quite a bit before they are registered, the tyres may in fact be older than you think!

 

Most people expect to change the tyres around the five year mark.

The MOT Tester's Manual can be accessed here: https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/510378/mot-inspection-manual-classes-3-4-5-7-vehicles.pdf

 

See Section 4.1 re tyres condition:

 

"1. Examine each tyre for...:

 

b. lumps, bulges, tears, exposure of the ply or

cord, or tread separation

Note: On radial ply tyres, care should be taken

to distinguish between normal undulations in

the carcass, resulting from manufacturing, and

lumps or bulges caused by structural

deterioration. " (my emphasis)

 

Does your tester know what he is doing?

Just returned from Spain and intend changing my tyres now as they are getting towards the limit. What have they achieved? 10 years puncture free travel, 49,000+ miles and still inside the legal limit. Needless to say I will be replacing them with Michellin as fitted from new. Well satisfied with these.

PS Spare is still unused in the garage!

My tyres are 'Kleber' marked with a small van icon indicator. These are manufactured in Poland to Michelin specification. They have been on my MH for 5 years and this year will be the 6th.

Have asked the MOT inspector and my service garage to do a thorough check and they have assure me they look in NEW condition.

Many things can look 'in as new condition' but sadly that means nothing!

As for 10 year old tyres on a motorhome *-) ....I suppose at least nobody was killed (lol)

 

Checked regularly by tyre specialists ATS Euromaster and annually for MOT-why waste money if there is no problem. If specialists say they are sound why believe anyone else who says they're not?

Michelin have indeed changed their advice re tyre replacement and recommend the 10 year rule which is the nationally accepted one.

Some time ago they also changed their 'tyre pressure' advice, to the nationally accepted one, and now suggest that 80 PSI in rear tyres is the norm......even when the tyre is marked 'Maximum 70 PSI'.

 

Two points...1. This thread was started because an MOT expert gave the wrong advice......would he be the only qualified expert (MOT or Tyres) who was wrong?

2. 80 PSI in any motorhome tyre is ridiculous.

 

Thank goodness for progress :-D (lol)

................................

80 PSI is approximately 5.5 BAR. The common maximum axle load for a Ducato based motorhome is 2 tonnes. At that load, Continental recommend their 215/70 R 15 CP tyre is run at 5.5 BAR. So, not so ridiculous. It depends on the tyre, the axle load, and what the tyre manufacturer recommends.

I refer you to Page 4 of this file:

 

https://www.michelin.co.uk/content/pdf/TC_Safety_Guide_UK.pdf

 

It should be abundantly clear from this that Michelin’s advice about inflating a motorhome’s tyres to 5.5bar (80psi) applies only to their CP-marked products (ie. “Agilis Camping”) when those tyres are used on a motorhome's (single fitment) rear axle. Also, that this advice is not something Michelin has arbitrarily thought up out of bloody-mindedness, but is based on guidance from the ETRTO.

 

Only three European tyre makers (Continental, Michelin and Pirelli) currently market CP-marked tyres and the manufacturers’ technical data all indicate that those tyres may be inflated to 80psi. Michelin’s “Agilis Camping” pattern even carries an 80psi datum on its side-wall.

 

If Michelin is asked for advice regarding suitable inflation-pressures for a Michelin tyre that is NOT CP-marked, if that tyre has a design-maximum pressure of (say) 70psi Michelin would never advise that it should be inflated above that pressure.
