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.
On my ‘86 4/4 this would be an indication of sliding bush wear causing the tracking to go out
Easy to check for bush/kingpin wear with both front wheels jacked off the ground. Hold tyre at 6 and 12 'o clock and alternately push at top and pull at bottom then reverse. You will easily feel wear if any, except perhaps just after greasing. If it's only just felt, not recently greased and it's not loose wheel bearings (unlikely) then you have 5,000 miles or more before renewal really needed. Such minimal wear may not be picked up by annual test either.
