Tire pressure is the simplest performance and safety adjustment on your BMW R 1300 GS — and the easiest to get wrong. Run the factory figures: 36 PSI front / 42 PSI rear for solo riding.
Check pressures cold (before riding) at least weekly. A tire just 5 PSI low handles worse, wears faster, and runs hotter. Pressures rise by roughly 1 PSI for every 10°F of temperature change, so recheck when the seasons turn.

How to check and adjust tire pressure
- Check pressures cold — before riding or at least three hours after a ride.
- Remove the valve cap and press the gauge firmly onto the valve stem.
- Read the pressure and compare it with the figures in the table above.
- Add air in short bursts with a pump, rechecking after each one.
- If pressure is too high, press the valve core briefly to release air.
- Refit the valve caps and check both tires every week.
- Recheck after long motorway runs or big temperature swings.
Common mistakes to avoid
- Checking pressures hot, which reads several PSI high.
- Trusting a petrol-station gauge without comparing it with your own.
- Ignoring the rear tire when carrying a pillion or luggage.
