We'll I true them to 63.5 in the rear and 63 in front to start at the moment, and run them to 56mm and that takes about 50 - 55 minutes on our track that is quite abrasive.
I change left to right about halfway, If you don't you're looking at about 45 minutes before the outside get's too small. You could of course reset the ride height and run them a little smaller but That is not something I want to do as it would compromise the objective of the test (finding a setup that works with big and small tires)
Julius, are they worn down evenly, so both front and rear are @56mm at the end? What do you think about a little higher OD ratio, say 0.5mm larger front tires? Thanks.
