What PSI range do I need for a truck or motorcycle?

Passenger cars rarely exceed 50 PSI, but light trucks, RVs, and many sport motorcycles routinely run 60–90 PSI, and trailer/commercial tires can hit 100+ PSI. Reviewers consistently recommend a gauge rated to at least 100 PSI for trucks and 150–200 PSI if you also air up trailers or bicycle tires with high-pressure road setups.
