Always check air pressure when your tires are "cold." If you check air
pressure when your tires are "warm" — even if your Honda SXS has
only been driven for a few miles — the readings will be higher. If you
let air out of warm tires to match the recommended cold tire
pressures, the tires will be underinflated. Be sure to check tire
pressure at the driving site, since changes in altitude and
temperature can affect air pressure.
The recommended "cold" tire pressures are:
