What’s the lowest tyre pressure that’s sensable for a Tandem

[PeterCarole29]

The rim and the tyre have to be tubeless compatible. Then, instead of using a skinny innertube to contain your air, you use the thick tyre carcass. The sealant fills the gaps and the vast majority of punctures without you even noticing. Run over a hawthorn branch with inch long thorns? No problem, you might just lose a psi or two while the sealant rasps out for a couple of seconds.

Setting up tubeless can be a pain. And it does loose air a little more quickly than a tube. The sealant does dry up everyday. If you're only using the bike occasionally, it's probably not worth it. But for regular rides, it's way better than tubes.

Also, lower pressures, more comfortable, but less rolling resistance. Win-win.

Thanks for the explanation .I now understand and for our use travelling at max 15mph and daytrips on roads i will stick with tubes

Correction... I meant to say the sealant does dry up eventually (not everyday!). You need to top it up every 6-12 months. Or if you've left the bike stationary for a few months.
