Decades towing my Seven; twin axles always. With a spare wheel. - Brian James Minno Shuttle is mine, can be found cheap these days, but be ready to replace all the 20 year old bits. Once done one has a practically new trailer. anthony

Had a blow out last week on the way to Prescott.

Happened at probably the worst time and in the worst place. M6 Birmingham Friday 4.30 PM and it was in lane 2 of a busy smart motorway section.

Eventually managed to get into lane 1 but no way was I going to stop in a live lane with traffic as it was. Drove nearly a mile to the next junction with my tyre shredding.

I am so glad it wasn't a single axle trailer.

I've never seen 10" or 12" trailer tyres over here that are fit for purpose for towing at the allowed 120km/h / 75mph speed limit, 13" seem to be the smallest tyres that have at least an "L" speed rating (normally matched with at least a 91 / 615kg load limit). The wheel bearings also take more of a beating with the higher rotational speeds of the smaller wheels.

From my son's experience of large (5,000kg) twin axle trailers, if one tyre fails, the other on that side will probably not last very long after, as it is likely to have been overloaded if the trailer is near it's rated limit and should be changed as soon as practical after the failed tyre.

This one didn't just fail. The truck in front kicked up what was later found to be a large right-angled steel bracket which went straight through the centre of the tyre.

I have had two separate blowouts over a period of fifteen years or so of towing my Caterham around.  In both cases it was a single tyre failure on a twin axle trailer and, again in both instances, it wasn't immediately obvious that there had been a failure such is the stability (and built-in redundancy) of four-wheeled BJ trailers. 

After the second failure I replaced all four tyres on the trailer with better quality items, specced with a higher load (and speed?) rating.  It's not a bad policy to replace trailer tyres (and to consider the ratings) every four or five years or so, even if mileage covered is quite nominal - the cost was not excessive.

However, I remained concerned that I might not know of any future failures which ultimately led me to the TyrePal remote TPMS system.  It is absolutely brilliant; a solar powered control unit that you place on the dash when towing and it displays individual trailer tyre pressures (and temperatures), picking up data transmitted from senders mounted on the valve stems.  The peace of mind is very reassuring - and it's quite interesting (in a geeky kind of way) watching the tyre pressures change as the temperatures vary, and it also transmits an audible alarm either when pre-set (low) pressures are detected or when an abrupt change in pressure (such as from a tyre failure) is sensed. 

Highly recommended - worth looking up (and maybe even worthy of a Club discount being explored)?

The most common cause of tailer/caravan tyre failure is old tyres. How many ads have you seen for trailers stating that there is "plenty of tread" or "they look like new" yes but how old are they? Trailer & caravan tyres don't wear out, they always look "like like new".

My policy is to change all 5 every four years, always  making sure that they are quality tyres of the correct load rating.

From the Caravan Club website, I hadn't thought about the last line :

When to replace caravan tyres

Caravans do a fairly low annual mileage – on average around 2,000 miles a year, so it would take many years of use to wear out the tread.

However, two or three factors can make them deteriorate in a different way, even with careful use.

All tyres age and deteriorate due to exposure to sunlight and atmosphere, even if not used.

Caravan tyres can suffer fatigue due to the repetitive small impacts they suffer in everyday use.

Being stored for long periods of the year without use can put undue strain on one particular part of the tyre.

It should go without saying that tyres which are damaged or worn to the legal minimum tread depth must be replaced immediately. Caravan tyres need regular replacement, irrespective of their visual appearance. We recommend that you replace your caravan tyres when they reach five years old and should never be used when more than seven years old.

If your tyres need a high inflation pressure (50psi or more), you should check regularly for signs of deterioration from three years old and should not be used when they reach five years.

Remember – the tyres age starts from when it was made, not from when it was fitted.

I've had two wheels come off, without punctures/flats. The wheels were supplied by a non Brian James supplier and the wheel centres simply sheered out. Most disconcerting. moral of the story is make sure the holes for the wheel studs are the right size, which one cannot see by eye. I replaced all five when I realised what was going on. The (my) spare suffers greatly from sunshine as it is open and static 24/7 Anthony

With a long low single axle trailer a single tyre blowout is unlikely to be too frightening. I had one go on a boat trailer and the only indication of a problem was a slight vibration. The mudguard also got slightly damaged due to the flapping bits of rubber.

Having extensively driven both and always having to reverse into a drive way its got to be twin wheel
