This may be a stupid question but how much does tubless sealant weigh when its dried up on inside of the tyre videos you watch online always say top up sealant every 3 months or so but make no mention of cleaning old stuff out?

Surely it comes to a point where you'll have a few added grams of rotating weight that is undesirable?

Sealant by weight is mostly water. The dry weight can't be very much, a few grams as you say. Bear in mind that that sealant may be hiding some punctures so is still useful.

I did once remove dried Stan's sealant from inside a tyre and concluded that it's a waste of time. Up to you though, it doesn't make much difference either way. The biggest beneficiary will be your OCD tendencies.

The trick to avoid ocd situations is to ride so much you'll wear out a tire in the time it takes to refill sealant once. :lol:

It's something like 15% solids (stans) so, not much.
