First of all, thanks for including me in the circulation of the pilot issue of Caravanning Answers and congratulations on a great new publication. I particularly liked the video clips accompanying the Italian Lakes feature.
I’m writing to alert your readers to the dangers of running a caravan on old tyres. Recently my wife and I were caught out when a tyre on our Avondale Rialto ended up in shreds as we travelled back from Cornwall to the Midlands.
Although we were on the motorway, our speed wasn’t excessive and we were in the inside lane at the time, so we were able to come to a fairly controlled and safe stop. In different circumstances it would have been a disaster but, in the event, we simply bolted on the spare and went on our way.
Next day I took the offending wheel to a tyre depot recommended to me by my local caravan dealer and told them of my surprise that the original had blown. Although it was several years old (original equipment on the ‘van in fact), I had inspected both tyres before our trip and contented myself they were in perfect condition and correctly inflated.
It turned out the man at the tyre depot was a caravanner himself (and a friend of the caravan dealer who had referred me), so he knew his stuff and I thought it worth passing on his advice to your readers.
Apparently, because caravans tend to do less mileage than cars, it takes much longer for the tread to wear down and, after a few years, the rubber starts to go brittle and can develop hairline cracks that don’t show up in a cursory visual inspection. The fact that many caravans stand for months in the same position adds to this problem.
Therefore, it is regarded as good practice to renew caravan tyres every five years regardless of the tread condition. You can tell how old each tyre is by looking for the DOT (Department of Transport) Code on the tyre rim. This is a code with 11 or 12 numbers/letters, the last four of which tell you when the tyre was made. For example, 0508 means the tyre was manufactured during week 5 of 2008. For tyres manufactured before 2000, its the last THREE digits that give the manufacture date - for example 118 means the tyre was manufactured in the 11th month (November) of 1998.
