Before making promises about collection, coordinate the inspection, paperwork, seller release and transport. Give each part of the purchase its own check.
A US-standardized number on every street tire indicating relative wear life. Baseline is 100. A tire rated 400 should last 4x as long as the baseline. JDM time attack and grassroots motorsport classes typically cap competitors at 100, 140, or 200 treadwear to control tire grip levels. Lower treadwear = more grip.
