Pumping up tubeless tyres

[YellowV2]

Yes of course it's personal choice but you don't need 90 psi, they are designed to run at lower.

Just to update I topped them up again today and tried the technique above. Leave the valves at the bottom for a few minutes then spun them to the top and it worked much better

I move the valve to the top, undo it and let a bit of air squirt out to clear it. Then inflate. If the valve does get too clogged I can just remove it to clean or replace. The sign of a clogged valve is when the gauge on your track pump keeps climbing or is slow to return to actual pressure.

Another tubeless question if anyone can help. I have decided to fit some tubes whilst I wait for some new tyres to arrive. With the tubeless tyre fitted would you run lower pressure still with a tube fitted or would you go back to normal tube and tyre pressure?

Normal. A tubeless set up facilitates lower pressures, with benefits to comfort and grip, but you don’t have to run soft. With a tube in you run the risk of a pinch puncture if you run too soft.

Going back to your original question, how old is your track pump?

I had a basic Halfords one which had given good service over many years.

But when I replaced it with a basic Giant one which was on offer from Edinburgh Bicycles, there was a marked difference in performance.

In t'other words, the Halfords pump had worn without actually failing.

As regards putting tubes into a tubeless tyre, that will be a messy job.

I would avoid doing it unless I really had to.

Unless you fully clean the inside of the tyre, some of the sealant will get onto the tube.

That doesn't matter - until you have to fix a puncture at the roadside.

No problem if you have a spare tube to put in.

My pump is fine, I just had a shop fit 2 tubes into my tyres and it pumps them up fine as expected.
I use quite high pressures being 90+ kg think I used to run about 95-100 on my tubes and about 80-85psi tubeless. Now being the tubeless tyres have a thicker tougher compound I didn’t know whether they would be ok around the same lower pressures

 

[Pale Rider]

I'm in danger of losing track, but we seem to be talking about 80-100psi in tubed and tubeless tyres.

Any combination of the above would be fine, so it's really all down to rider preference.

For what it's worth, I believe most roadies who run tubed at 100psi tend to drop by about 20psi for tubeless.

What width of tyres are you using?

As a general point, the wider the tyre, the lower the pressure.

I’m running 28mm tyres.
My question was about now I am running tubes but inside tubeless tyres. With the tubeless tyres being stiffer than the normal tyres could you run lower pressure still for the same benefits but just using tubes

 

[YellowV2]

If you are using tubeless tyres with tubes in, you treat them as normal clincher tyres and run at your normal pressure.
