I am not very happy. I have had two tyres that have burst on me, one when I hit the curb, going at 25 miles an hour, and then one more when I hit a pothole both tyres split.The aluminium rim splits the tyre both times. despite it saying the sidewalk is reinforced not a happy chappie tyres were only eight months old. at approximately £500 a time. No joke.
