Step 1 - Removing Your Inner Tube


First of all remove the inner tube valve and deflate the tube.
Undo the rim lock, leaving the nut on the end of the thread.
Now completely break the bead away from the rim using a bead breaker or tire irons.
Starting opposite to the rim lock start levering the tire off the rim. At this point always ensure that the side opposite to that you are working is pulled into the spoke recess. This will allow the tire to move across to the side that you are working and thus allowing it to be removed much easier.







--------------------------------------------------------------------------------

Step 2 - Removing The Tire


Having now removed the inner tube. Turn the wheel over and following the same bullet points mentioned in step 1, lever the tire from the rim.
Whenever fitting or removing tires directly on the ground, always remember to work with the brake disc top side. This will prevent any damage occurring to the disc.







--------------------------------------------------------------------------------

Step 3 - Tire Fitting Preparation


Inspect the rim, rim tape, spoke nipples and inner tube for any irregularities before commencing with the refit.
Clean all components and lubricate the bead of the tyre, ready for fitting.







--------------------------------------------------------------------------------

Step 4 - Refitting, Side 1


Insert the wheel into the tire, rim lock first.
Now is the time to make sure the tire is being fitted in the direction that you require.
Once again, ensure the bead is set right into the spoke well of the rim and the tire will lever on easily.







--------------------------------------------------------------------------------

Step 5 - Refitting, Side 2


Now turn the wheel over. Before fitting the inner tube, slightly inflate the tube to the point that it will still droop over your arm. This will help stop the tube being caught between the rim and the bead when fitting.
Insert the tube, valve first.
Now lubricate the tire bead. Start fitting the tire at the rim lock first, once again ensuring that the bead is set right into the spoke well. This is important at this stage.








--------------------------------------------------------------------------------

Step 6 - Don't Pinch That Tube!


Now you have got this far, you don't want to pinch that tube. So, as you lever the tire make sure that the tire iron doesn't go much past the vertical. Pinches are caused by letting the tire iron go too far inside.
You may need to use your foot to stop the tire bead riding out from the rim at the opposite end.







--------------------------------------------------------------------------------

Step 7 - Now The Hardest Part


You will now have arrived at the most difficult part, the last quarter!
Instead of levering three inches of tyre at a time, you will now need to lever one inch at a time. You will find that this will enable you to easily fit that last part.






--------------------------------------------------------------------------------

Step 8 - Finishing Off


Now that the tyre is on, you haven't quite finished yet !
Using a tire iron pull back the tire and check that the tube has not been caught between the rim and the tire's bead. If it has, try inflating the tire and deflating, usually this will free it. This is quite important, due to the fact that most rim pinch punctures (while riding) are caused by the tube being caught while fitting or through compression punctures.
Finally, inflate the tire up to seat the bead onto the rim, tighten the rim lock, then set your tire pressure. For most off-road riding/racing a pressure of 12 - 14 psi is suitable.
