Have acquired a 2011 Renault Espace with the Prestivo PV-S1's on the front. Have done 2K miles since then & found mixed results. Don't know how old they are but feel they are degrading somewhat quick. Better suited to a smaller, lighter vehicle than two ton Tessie from Teddington! Good grip in wet or dry but feel every bump in the road. Believe they may be Yokohama's. Plenty of central tread depth left but outer 'shoulder' seems to be wearing down more quickly. Also my NSF has a tendency to go soft on me over 3 days. Will look into that tomorrow. ?Slow puncture, faulty bead/valve, old age, don't know. It's not a bad tyre, maybe not the best for a 2 ton Espace. Can't take a chance with tyres if carrying 7 people.
