Tyres
Always check air pressure when your tyres are "cold." If you check
air pressure when your tyres 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 tyres to match the recommended cold tyre
pressures, the tyres will be underinflated. Be sure to check tyre
pressure at the driving site, since changes in altitude can affect air
pressure.
The recommended "cold" tyre pressures are:
