If your usage pattern involved sprinted driving and/or track usage,threadwear information is useless
What become important is how does the tyre hold up to heat cycle
Some tyre have big loss of grip after a few track session while some can retain most of it down to end of life
Look into extreme performance cateogry for such usage pattern
Some tyre which does not stand up to usage pattern like this will actually finishes off its thread and/or lose grip quickly,rendering threadwear information useless
