Road-Trip Tire Pressure Checklist
Check cold pressure, tread, sidewalls, spare, and load before a long drive.
Short answer
The night before or the morning of a trip, check every tire cold against the door label, inspect for nails and bulges, confirm the spare is ready, and use the loaded pressure if the placard has a loaded column.
Highway speed and heat punish a tire that was 'good enough' around town. The trip checklist exists because people pack the car and skip the monthly habit in the same week.
If you add a roof box, four adults, or a hitch load, look at the loaded listing on the label. Do not invent a higher number because the car 'feels heavy.'
Put a gauge in the cabin, not buried under luggage. A station 200 miles later is a bad time to discover you cannot measure.
