I am on my second set of Tourance Next tyres,the previous set did around 11k.miles.and the present set are about half worn at about 7k.miles.The only problem I had was a rear puncture with a large hole in the centre of the tread.I had obviously run over something.All I felt was a vibration and as I pulled into a lay-by the tyre went flat,I had to be recovered and have a new tyre fitted.The set I have on now are in really good condition with hardly any squaring off yet.They are really stable for motorway running and are great in the wet,Much,much better that the original Tourance,and streets in front of the original Trailwings rubbish that were on the bike when I got it.
