How to Change a Flat Tire on a BMW R1200GS

Front Tire Removal
1. Park your BMW R1200GS on a solid, flat surface with room to work on each of the sides. Lift the motorcycle off the ground using the center stand or motorcycle jack so that both tires spin freely.
2. Release the two retaining clips securing the ABS sensor cable to the brake line if removing the front tire.
3. Remove the two larger brake caliper securing screws with an Allen wrench. These screws are found nearest the fork and secure the caliper in place. Forcefully remove the brake caliper from the wheel rotors by rocking the caliper back and forth while pulling on it. The caliper will then freely hang from the brake line out of the way from the wheel.
4. Loosen the axle clamping screw, with an Allen wrench, on the front near the bottom of the fork if looking directly at the BMW R1200GS.
5. Attach the socket extension into the square drive of the 7/8-inch or 22 mm spark plug socket backwards. The hex end will then become the front end of the socket, and the cylinder end will face the wrench.
6. Insert the hex end of the socket into the sunken-in axle bolt located at the bottom of the front fork. Rotate the axle bolt counterclockwise until it loosens, and you can pull the axle out.
7. Remove the front tire and replace it with the new tire before sliding the axle back through the fork holes. BMW recommends torque specifications of 50 Nm for the quick-release axle bolt and 19 Nm for the axle clamping screw.
8. Slide the caliper back onto the front wheel disc and tighten the securing screws to 30 Nm. Once the calipers are correctly mounted, squeeze the front brake lever to bed the brake pads back into place. Finish by closing the two retaining clips holding the ABS sensor onto the brake line.
Rear Wheel Removal
9. Park your BMW R1200GS on a solid, flat surface with room to work on each of the sides. Lift the motorcycle off the ground using the center stand or motorcycle jack so that both tires are off the ground. Place the motorcycle in first gear to keep the rear wheel from spinning.
10. Unscrew the five wheel studs with the Allen wrench while supporting the wheel, which will free up the rear wheel.
11. Pull the rear wheel towards the rear of the motorcycle until it is completely free from the chain, rear brake pads and swing arm. Place the rear wheel off to the side.
12. Align the new rear wheel with the wheel stud holes and tighten each of the wheel studs in a diagonally-opposed sequence. BMW suggests each stud has a torque specification of 60 Nm. Finish by carefully lowering the motorcycle jack until both tires rest on the ground.
