🎒 Full Cargo & Heavy Passengers
When carrying maximum passengers or heavy trunk cargo, increase cold pressure by +3 to +4 PSI (36 PSI total) to maintain carcass structural integrity and prevent shoulder tire wear.
❄️ Winter & Cold Weather Drops
Ambient temperature drops reduce air pressure by ~1 PSI per 10°F (5.5°C). If ambient temperatures drop from 70°F to 30°F, set cold inflation to 37 PSI in a warm garage to avoid driving under-inflated.
