Just took my bikes out of Storage. I never bothered to drain the sealant out prior. I guess that old sealant is not as effective now. Do you ppl change it out completely or just top it back up.

If it formed a dried-out blob, peal it out. If it is still liquid, top it off. It is likely still as good as the day you put it in there.

I was hoping someone would recommend that. Thanks. 😅

You could also try what I do:

Don't even look. Just put in more sealant.

Funny.

Top up.

If it's been in storage for a year or so (6 months or so in arid climes) I'd expect it to be bone dry.

I'd first check to see that all beads are still set by putting some air in there. If a tire only kinda holds air dry but the beads look mostly set I'd go ahead and add sealant and do extra thorough Stan's shakes (and bounces, you know the whole Stan's dance).

If a bead won't even come close to setting dry you may have to peel off the tire, clean the tire bead and rim, and unfortunately there's a good chance new tape will be needed if you have taped rims.

I i just top it off if it needs it. You can pull the valve and check with a dipstick, or take the wheel off and give it a side to side shake and see it you can hear anythjng sloshing around.

I’ve never bothered removing dried sealant, but I seldom have a tubules tire on a bike for more than a year of two before it is worn out anyway.

You are not seriously considering riding on last season's air, are you?
I like to start each season, or a long tour with fresh air.

I prefer to not take tires off unless I have a little time to clean the beads and take off any dry sealant. Then I use soapy water to re-seat the beads, Usually, I just put new sealant in. Your old sealant is completely dry, in all likelihood.

I installed new rim tape and sealant last year just prior to stopping my rides.

So today I just deflated the tires, pop one side and topped it up. I have a bad habit of overuse of sealant so it's never dried out completely.

I think it would depend on the type of bike, road bike where you could have a dried clump it might effect the ride at higher speeds, mtb where a clump wouldn't have the same effect I'd just add more and move on. Our house we mix the type of rides we do a lot so MTB tires can last 2 years, I just add more when I think it needs it through the valve stem and don't touch the tire.

This is exactly what to do.

No need to pull the tire and clean it out or anything. Clean things up when the tire need to be replaced.

So true!! I read a review of 2022 air vs. 2023 air on the Bicycling website. Turns out that 2023 air is waaayyy faster!
