Quick step by step guide on how to change a mountain bike tubless tire quickly and easly without an air compressor. With a few pro tips from Jim Buchanan.

As a racer jim is always changing tires and shows you a few tips he has picked up along the way. This is part of the MTB Vlog how to series subscribe to our channel for more tips and tricks.http://goo.gl/BcuctO

It is now accepted that tubeless tyres offer much better performance than running inner tubes. You are much less likely to get a pinch-puncture, they are pretty much thorn resistant, they shed valuable rotating weight and you can run much lower pressures and still keep a relatively good rolling speed.


A few years ago they were considered as â witchcraftâ by some, but even though they are now very popular â people still seem to have some funny ideas when it comes to fitting tubeless tyres. We decided to cut out the bullshit and get some professional advice fromJim.

Difficulty : Easy

Tools Required
Tyre Levers
Scissors
Rim Tape
Spike
Tubeless Fluid
Rag
Cleaning Solution

To prevent the tyre burping, it needs to be seated nice and tight, you shouldnâ t be able to fit it with just your hands! Start off with cleaning the rim and the bead, removing any dirt, old tubeless fluid etc, next Jim degreases it, this helps the tape to stick. When applying the yellow tape start it off on the opposite side to the valve and wrap two layers really tightly, making sure there are no big air bubbles underneath it. Keep adding the tape onto the channel of the rim (yellow or gorilla) until you reach the desired height to keep the tyre nice and tight. Use two layers of yellow Stanâ s tubeless tape and a Flow EX rubber strip. Depending on the rim you have you might need more layers of yellow tape, or gorilla tape if youâ re on a budget.

Put the wheel inside the tyre, put one side of the tyre on the bead (this should be just doable with you hands)

Give the fluid bottle a good shake and then pour the fluid in, making sure the bottle is upside down, otherwise the crystals will stay in the bottle and wonâ t seal your tyre. Next put the other side on using a good plastic tyre lever.

the least amount of fluid he can get away with for weight reasons, and also because he changes the tyres daily (whilst out on the race circuit) so the fluid never goes off and sets into a hard rubber lump. Obviously this is a bit excessive for your average trail rider so Jim suggests using the recommended amount written on the back of the bottle for everyday riding and checking its consistency from time to time.

Next, make sure the rim strip is not caught by the tyre and still looks evenly spread. spraying with soapy water will also help it to seat properly.

Now pump the tyre up to 40 psi, holding the tyre above the valve slightly to the side (this helps the inflating procedure when using a track-pump) or use a pre changed pump or Airshot for instant inflation.
Wash the excess fluid off, then Jim does another unusual trick, he wobbles the wheel and taps the sides o to make sure the fluid gets into to all the nooks and crannies to fill any possible air leakage gaps.

The last procedure is to check if the bead is even above the rim line and set the tyre pressure to your correct preference. Jim advises to check regularly that you still have plenty of tyre sealant in the tyres and top up if and when required
