Just had a shocking experience todayon my 2006 xs sorento.The spare wheel has dropped off and carried on rolling down the road, fortunately it hit nothing and no one was hurt. Had 4 new tyres in January and the best of the original went on the spare. Car was serviced in February nothing was noticed with spare wheel when pressure was checked. Wheel has gone back on again and there appears to be nothing wrong, in fact it looks impossible for the wheel to come off unless the holding wire snaps, but this is not the case. Has anyone else had this happen to them? or is it one of lifes little misteries.
