I have an Ifor single axle unbraked trailer, bought to shift the contents of my garage / garden / house from Kent to Lincolnshire and then to take bikes for track days later this year. It was virtually new and clearly unused for any hard work when I got it late last year, since when it has done about 4500 miles in 11 return trips since mid December. All with no problems. On Sunday it blew a tyre out on the A46 north of Lincoln. The tyre had well overheated, as found when I picked the tread and sidewalls up in the middle of the carriageway. Had detected a slight wallow shortly before the blowout. Tyre was in perfect condition before setting off, pressures all correct, trailer not overloaded but close to capacity, so I can only surmise it took a puncture and as it was losing pressure it overheated and blew. Judging by the number of tyre carcasses I saw today between Grantham and Lincoln (and one or two busy mobile fitters) there must be a few nails on the roads in that part of the world). Anyway a bit of research shows that I can get the same size tyres with 8 and 10 ply construction (it is fitted with high speed floatation tyres, 4 ply), and higher load capacities. But I suspect they will blow out just the same if they get overheated in the same way. Anybody got experience or knowledge on this? Would I be wasting my money by up-rating the tyres?
