Afternoon all from a mixed bag of weather in France.
I was greasing the front suspension and inspecting the wheels today, when I noticed that the tyres, at 10000 miles and four years old have 6mm of tread depth on the outer groove and 4mm on the inner, on both front wheels. There are no other visible signs of tyre wear and I don't know how long this has been going on. This years control technique did not flag it. Could the team advise please. Thank you.
