Possible wrong tyres

[colin-yorkshire1]

brilliant well done Smurff, I like your style

, I see he recommended 99Li sounds ideal.
ps, when the fitter arrives check the date on tyres before fitting. ideally they should be no more than 6mths old for a trailer.
might as well get it right now you have a result.

Glad you got sorted. I contacted Lunar about the tyres on our caravan. Lunar contacted the dealer and we now have to take the caravan to the dealer for the tyres to be checked. Apparently the load index should be higher as 100kg is not enough of a safety factor. Originally the MTPLM was 1735kg, but we had it upgraded to 1800kg however they never upgraded the tyres.

same when I upgraded my payload Bailey did not make any reference to tyres but when I contacted them they were very helpful but really I had decided in my own mind to upgrade the tyres. Funny thing though when I got a new tally plate, guess what the tyre info said? Yes it detailed the OEM spec and pressure regardless of the upgrade. I guess it is correct as the MTPLM is 1400 and the two OEM tyres take 1420kg. So when I sell the van I will make sure the next owner gets the information as all documents have been annotated etc but whether these get handed over by a dealer remains to be seen.

BTW for the more knowledgeable trye experts amongst you, if you have tow of the same size tyre but one has a maximum pressure of 42pi and the other 36psi, what does that imply regarding the characteristics of the tyre? For instance, would the 42psi one be more of a heavy duty tyre than the 36psi tyre?

 

[otherclive]

What are the specs for each tyre?

What are the specs for each tyre?

The tyres are 175/65 R14. Load index is 475kg. Max trye pressure 36psi. Manufactured in 2009.

 

[otherclive]

Are the 42psi ones exactly the same make, spec and year, apart from a higher max pressure marking?

Clive,
By definition if any part of the specifcation is different (i.e. max pressure) they are not to the same specifcation.

Smurff don't forget your spare wheel. Yes thanks for reminding me, as mine is in a carrier under van, I'm gonna have to read manual as all my others were in gas locker, and if this is incorrect as well, they're. Going to have to dig deeper, I would like 99 or maybe higher if possible but I cannot seem to find this size over 96, unless I go for a different size which would mean changing the spec and having the M/M moved.

Smurff GT Radial Kargomax st 6000 is in your exact size and has a Load Index of 102. I have used these and my spare is this tyre. In my previous posts I have given the size of the Firestone Vanhawks that are slightly narrower but have the same OD within a couple of mm as your existing tyres. The Vanhawks are LI 102. In that revised size there are many more makers available than for your existing size.

Smurrf I am surprised that after so many questions and helpful replies you keep asking the same questions again. What make syour 95H tyres unsuitable is that the Load Index is below that required for your caravan's weight. Put bluntly if you load up you caravan to its full MTPLM you will overload your tyres. Even if you dont load it to its maximum load the tyers are below the LI recommended by Bailey. You wouldnt put low LI tyres on your car would you? The H is the speed rating as Lutz as answered above. H is for tyres that can be fitted to vehicles with a continuos speed capabilty of 130mph. Now I would think this would somewhat more than your caravan would require. Your Service Handbook tells you quite clearly what tyres are recommended by Bailey. They will have a lower speed rating than H and again as Lutz says would be N which is for a continous speed at their maximum load of 87mph. More than enough for most caravans I suggest. However, if you should upgrade your tyres to higher load index than 96 you will probably go for commercial van tyres (Transit etc) which will probably have a speed rating that is higher than N. My Firestone Vanhawks which I bought to replace the same size tyres as yours are 185/80/R14 with a speed rating of R which is good for 106mph. So if you get the right tyres for your caravan speed rating will always be more than enough for use in UK or Europe.

Here is a link that expalins Load Index and Speed Ratings. http://www.blackcircles.com/general/load-rating
I really think that you should be talking to your dealer by now.

185/80/14 look at websites such as Blackcircles

Clive,

not correct Prof as I did exclude the max pressure from the question on specification by use of the word "apart". So was the maker, load index, temperature, wear, reinforcing plys, ply material etc, in fact everything apart from maximum pressure the same as for the lower pressure tyres.

Ian, the 42psi is a 'Reinforced' (car) tyre as opposed to the other that can be considered a 'standard' (car) tyre. (Reinforced tyres AKA, XL or extra load)
The problem arises because each of these different construction tyres requires a different pressure for the same load, one of each then at either end of the same axle would be illegal

thanks yet again, I really really do not belive it ( no I'm not victor meldrew) but feel like it, the bl**dy spare was flat not only that but 8 yes 8 years out of date made in 2005 how the hell can a dealership which is possibly the largest in the uk treat customers like this, I feel I want to name them but maybe not, this is not just poor service this is bl**dy dangerous, ok they are changing them but I cannot move van as my insurance won't cover me while these tyres are on, is there a body I could complain to

 

[otherclive]

Unfortunately there is no legal requirement on a tyres age but 7 years max is a recognised guideline. But some will say that its only 8 years old and unused so should be okay as a spare. Not something i would agree with but do understand. For your under spec road tyres which were unsuitable for the van Trading Standards would be interested but unlikely to achieve you more than you have done for yourself. But they build up evidence and share it nationally which if bad trends were detected could lead to more enforcement or legal requirements. For the small extra cost I would expect your dealer to change the spare too.

The tyres on our new caravan were manufactured in 2009 so we have already "lost" two years. Is it perhaps 7 years in use and not storage?

That clearly demonstrates that the dealer probably never carried out a proper PDI on the caravan before handing it over. It makes you wonder if they removed the wheels to check the brakes and replaced the shot nuts? Did they do a pressure test on the gas systems and water systems for leaks?

whilst the dealer may not have carried out a proper PDI you cannot say that for certain based on the age of the spare as there is no legal timeline to change tyres.

The sprea was flat so shoudl have been picked up if a proper PDI was done. They probably only checked the other tyres visually from a standing position and as the tread looked good, it was handed over.

Can I just question the age caravan tyres should be changed?

Mine were 5 years old last year and on the recommendation of the dealer and CC I changed all four. Was I wrongly advised

It depends how you measure age, that's why both 5 and 7 years are involved.
The recommendation is to replace tyres within 7 years of the tyre manufacture date - in practice they may have spent a couple of years in the supply chain before being used by the customer, at the tyre factory, at the tyre distributor, at the caravan manufacturer and at the caravan dealer - that's why 5 years from caravan purchase date becomes a sensible figure.

In practice you might get 6 years by checking the tyre date codes and being lucky in a short supply chain.

If you buy readily available tyres by well known brands such as Michelin, Bridgestone, Hankook and they are commercial vehicle tyres I've found them to be within 6 months of manufacture. This is because they have a high turnover. Any older than 6 months and I ask for another tyre.
