Got a big trip coming up, probably 2000 miles. I'm putting a new rear on but I'm unsure about the front. It is a Bridgestone Battlax BT020, I don't know what the current mileage on it is.
It has about 1mm to go on wear indicators. Tread depth is 2mm in centre, 3mm one third from centre and 3.5mm two thirds from centre.
I believe tread depth is 4mm all round new, total life expectancy is about 10k miles so by my logic I should be able to get another 2k out of it ok?
