Bought two new tyres. Later discovered that one had been fitted incorrectly (the inside was on the outside!). Took car back and had tyre refitted. Later drove the car on the motorway only to discover that the wheel(s) were out of balance with shocking vibration. Took car back again and was told that one of the wheels was out of balance needing a 30gm, weight. Not sure everyone would have spotted the tyre error and I just wonder how that might have affected the car in, a) the wet and, b) in an emergency stop manoeuvre? Shocking. Summed up in two words: Never Again!
