Two x Bridgestone tyres with only 60miles run on them. Bought a car from a dealer and paid extra for a branded set of tyres to find afterwards that they are the wrong size. Only driven 60miles on them from new. One tyre has slight damage on the inside bead but held pressure perfectly while they were on the car. Bridgestone Potenza S001 tyres x2 in size 305/30/20 99Y. These tyres are designed for fast road use and offer excellent high speed performance up to 186 mph.
