Took my spare ivor williams trailer tyre,( the small ones) to my local tyre company, to see about replacing it, i was planning on making a long journey with my ivor williams tri axle flat trailer to pick something up? Any way, learnt something new, apparently according to the tyre man, tyres fitted to caravans and trailers must not exceed being more than 7 years old? Well i asked him how old this tyre was, from the date code on the tyre he could tell, that the tyre was made in 2008? Ive had the trailer from new, so it means all 7 tyres are illegal, out of date? So that scuppered that journey, and learnrt a new regulation? it makes sense in a way because short journeys the tyres will probabley last? but on a long trip on a motorway at reasonable speed the tyres will heat and come apart? Nightmare seniario?
