The 'bargain' BT021 I bought locally for $50 is totally gone at 7000kms, so not much of a bargain at all. The Border run basically killed it. It looks like I used it on track days as the side tread is really worn. I now know why Bridgestone replaced it with the BT023 - all the reviews about it not being that great were correct.
Next up a set of Michelin PR2s in 110/80-18 front and 170/60-17 rear. To be worth in $$ wise comapred to the Shinkos I have been using I will have to get around 24,000kms out of them, which I would have thought totally impossible a few years ago. Stay tuned.
