Nearly new tyres


  1. 🙁

    This is the rear o/s wheel from my former 1967 Mk1 S – complete with 'plenty of tread', low mileage,Yoko 008. The Yoko was about 6 years old. Happened at 70'ish MPH on a dry bright summers day on the M6. Luckilly it all came to a steady stop on the hard shoulder with no damage to me, car or rim. Tyre was a bit beyond yer typical puncture repair though. So, beware all you users of Concourse 1960's SP's. If a modern design tyre can totally fail at 70 on a straight bit of motorway after only 6 years, what could your 40 year old tyres do?

    The important question is 'Why did it fail'?

    You see plenty of modern cars at the side of a motorway with a puncture and that is unlikely to be be down to age of the tyre.

    No puncture through tread face. Wasn't rubbing against bodywork or suspension – as you can see it was the outer face which failed. It was properly inflated. Failed without any warning.

    The car had been used for hillclimbs on these tyres – but that shouldn't have stressed the tyre so badly as to cause it to fail.

    It was a complete mystery failure. My local friendly tyre depot could only conclude that the rubber had hardened with age and whilst it looked fine (plenty of tread), it had simply overheated and failed.

    Had it been on the front during enthusiastic corning it might have been a trip to the body shop! Needless to say I replaced all 5 tyres immediately with 32's. Much better than the 008's anyway.

    I have recently had a 65 S on 3.5' rims with 'as new' 145 SP's on. They were as hard as hell and didn't grip the tarmac at all – looked nice though. Until I fitted Dunlop D1s and 32's the car inspired no confidence at all. And whilst the 3.5 rim obviously provides less grip than a wider tyre can, I have had decent tyres (when you could still get 'em) on S's on 3.5s which were perfectly good and buckets of fun.

    Hardened tyres – not good 🙁
