We had a truly horrific experience with tyres. Our MH was 10 years old on original rear tyres (fronts had been replaced due to wear). Three weeks after passing the MOT, trundling up the M5 at 65 mph in the middle lane when ‘BANG’ rear tyre completely blew, caused us to swerve and veer across the motorway. Gladly no other vehicles anywhere near us and we got to a stop on the hard shoulder with hearts pounding breathing a massive sigh of relief. The flailing shredded tyre did damage to the underside of the van which cost hundreds to put right. The tyres looked perfect but were 10 years old, low mileage. The tyre guy who rescued us explained that he had attended some bad accidents due to Aunty Doris (other names can be substituted) in 10 year old Nissan Micras (other vehicles can be substituted) with very low mileage have suffered similar incidents. This has made me somewhat particular and paranoid about the tyres on our motorhome. You only have one life and tyres are an essential safety feature. Get the right tyres for your van and when they pass seven years, swap them out or have them thoroughly inspected regularly. It’s the side walls that perish, often invisible on the outside of the tyre. I recently had a couple of Michelin Criss Climate Camper tyres on our Globecar Campscout and whilst £200 + each made me wince, I have no regrets and nor should you.
The new tyres should keep you happily motorhoming for another 7 years so enjoy !
