Non tubeless tires with tubeless rims

[qclabrat]

As the subject headers says, I've done this for mtbs and fatbikes without issues. But what about gravel and road wheels with much higher pressures?

Adding that the non tubeless tires will use tubes not tubeless sealant

as long as you use tubes anything will work, designed for tubes or tubeless, you only run into issues with getting tubeless to seal in some situations.

try it and see if it seals bro

Using tubes not sealant

From what I have read this is a no no. I really don't think this should ever be tried on a road tire at the pressure and speed it is not worth your safety.

In what way? He wants to run non tubeless tires on tubeless rims with a tube in the tire. Not seeing how this would be any more dangerous than any other tubed tire setup.

The big difference for tubeless stuff is the bead tolerances fits are tighter bc they need to hold pressure nothing really structurally different here

Maybe I misunderstood or misread. I thought he was saying running a tubless tire on a non-tubless rim without a tube.

Is the tubeless rim a hookless bead? IMO that would be the biggest factor. I have no way to confirm, but I assume all tubed tires are designed for a hook bead rim.

Other way around, non tubeless tires with tubeless rim

I should check, they are non tubeless Vittoria tires on 10 yo sram tubeless carbon rims.

On my road bike I have tubless ready rims but I choose to ride continental 4- season tires with tubes no flats this summer.

I bet it’s fine

It will either be fine or it will blow out on a high speed descent.

Those clincher tires rely on a hooked rim but it’s not apparent what the rims in question have.

I did the same with old Mavic UST type tubeless rim without anything going wrong but I do recall the fine print saying ‘don’t do that’.

If it wasn't safe, how could you ever put a tube in if you got a puncture?

I am not an engineer, but I think you are running a PSI of 90 to 100 so the tire seats better. I have ridden with have the tubless rims and tires running 65 to 80 PSI.
