How these guides are written
Each guide starts with a short, direct answer you can act on, then explains the reasoning, the checklist and the common mistakes. They describe general practice in the tire trade. Where a guide touches something that varies by location, such as which services a store offers, it points you to the store, because the store's own page is the reliable source for what it does.
Purcell Tire & Service has worked with fleets, farms, mines and drivers since 1936, from 64 locations in 14 states.
