Be careful though some tread wear bars are set at the recommended 3 mm change, others are set to the legal 1.6 limit.
Much better to use a tyre depth gauge.
I do like tyre leader, but will be sticking with RFT for multiple reasons.
Interestingly Tyre Leader sell the Pirelli P Zero RFT for the 20's approved for BMW and Merc, no where else seems to sell that variant. Before anyone suggests getting the non-approved version clearly there is a difference in compound make up as the approved version is better all round in testing...
