Tubeless tyre removal/refit question

[AndyDRZ]

Hi Guys,

I recently bought a set of second hand hope hoops for my 29er.

They came with good and nearly new tyres which are setup for tubeless. However, a quick look made me realise the rear one is on backwards.

If this was a regular tyre with an inner tube, it wouldn't take me long to whip it off and refit the correct way around.

What's the technique when it is tubeless? When I remove it, is goop going to drip everywhere?

Do I need to remove all the current fluid and replace with new?

I understand that although the tyres are unused, they've been fitted for around 2 years.

Thanks, Andrew

Two years years ?if they haven’t been topped up you will have a rubber golf ball inside ,I usualy check my sealant every two months ,if the fluid has been topped up just scoop it out and re use , get it wrong you can end up like the android on alien when cut in half .

Thanks! Love the imagery of that. I'll take a photo if it ends that badly

Get some "milk it" valves. You can check, remove and replace your sealant without removing your tyre or even letting the pressure down

When you remove the tyre let the air out then break the bead seal by pinching the sides of the tyre together like they do with a car tyre. Otherwise they are a nightmare to get off.

If they've been fitted before then they should seat ok but if you havnt got a air blaster tank thingy then mount the tyre with an inner tube to get it seated (it will "pop" into place), then just break the seal on one side to remove the tube. then you should be able to get the remaning side seated with a decent track pump. Remove the valve core to get more air in faster. Spray some soapy water on the bead too to make it easier.

or if you have a c02 inflator they work a treat to snap the bead back on

Thanks All,

I used the technique that lufbramatt suggested and it worked great. Thanks lufbramatt!

Tyre is now the correct way around. Just need to wait a little while to see how well it's holding it's pressure.

Happy days

I find they need a short ride to get them properly sealed, otherwise they lose pressure over a couple of days.
