Maximum Psi

…tire's maximum inflation pressure when next measured in "cold" conditions. A tire's "maximum inflation pressure" may be different than the assigned tire pressure used to rate the tire's "maximum load." For example, while a P-metric sized standard load tire's maximum load is rated at 35 psi, many…
