Do Slime tubes hold CO2 longer than regular

Just curious, I mainly fill with CO2 because it's easier, and I am now buying cylinders in bulk from Amazon, pretty cheap.

I noticed that CO2 inflated tires seem to lose pressure faster than air inflated. I believe this is scientifically accurate and not just my perception.

Do the self-sealing tubes such as Slime hold CO2 any better than non-self-sealing tubes?

How lazy can you get?
Use "real air" at home and skip the Slime. If flats are a problem, get a more flat resistant tire & tube.
Slime isn't fool proof and makes a mess if you want to patch.

You only fill with CO2? Even with "cheap" cylinders, that seems pretty ridiculous cost wise. I speak as someone who tops up his tires before every ride.

FYI yes, it's well known that CO2 leaks out faster from tires. CO2 is only meant to be a temporary fix after a flat, not a permanent way to keep your tires inflated.

Just use a floor pump!

Thanks for the judgemental replies instead of answering the question. How is it anyone's business how I choose to inflate a tire?

Non-answers like that are why forums get a bad rep.

Gotta agree with the others here that using only C02 cartridges is a little crazy and wasteful. You ride a bike around for pleasure and exercise getting all sweaty and tired yet using a hand pump for 1 minute every few rides is too inconvenient?? Consider it an addition to your exercise regimen. My apologies if you have some disability that prevents you from doing this and I don't know the answer to the Slime tubes question.

I wouldn't expect them to be much better. The Slime moves around inside the tube so if the bike is sitting still for an extended period the top part of the tube won't have much, if any, Slime on the inner surface so the CO2 will diffuse out over time. There might be less diffusion out from the very bottom part of the tube where the Slime accumulates, but that's only a small fraction of the overall surface area.

Thicker tubes will lose less pressure over time and the 'thorn-proof' tubes are considerably thicker so they would keep the CO2 in much better. But, as others have said, it would make more sense to just pump up your tires with air.

When you report using an inefficient and costly way to do a very simple job, "judgmental" replies have to be expected.

Please keep in mind that you are asking strangers for free advice and sometimes you get more advice than you might want. That's the price you sometimes have to pay for free information. Accept the good advice and ignore the bad.

And, yes, CO2 diffuses through rubber faster than air. It actually dissolves in the rubber:
Technical Q&A with Lennard Zinn - Large molecules and short frames | VeloNews.com

And I inflate my tires with good old-fashioned air from a pump.

You're doing it wrong. What do you expect? If you're looking for enablers for your bizarre choices go over to the money wasters forum.

Otherwise take the advice given. CO2 isn't for keeping tires inflated. It's meant for emergency quick fill on the road. It leaks. I doubt slime will help that. IMHO slime doesn't really help anything much.

Do you also wash your bike with Evian water?

Don't listen to the naysayers, OP;
You just need to switch from CO2 to nitrogen, so you need one of these: Flo Dynamics TYGER3 Nitrogen Filling System - Tire / Wheel

I bought a car but the radio is tuned to a station I don't like. Does anyone have a source of cheap car stereos that I can purchase pre-tuned to my favourite stations in my area? Also, I don't want anyone tell me that this is wasteful. Freedumb!

Nobody has even touched the "environmental issues".
I'm not an "earth muffin", but I'm not environmentally stupid either.

BECAUSE you asked a question which has a stupid premise.

So it's OK for YOU to be judgemental??

A poster with a total (currently) of 47 posts KNOWS about some perceived bad reputation of this forum?
IF you knew that, why would you even bother joining?

There's 1,000's of people that have received great info here. Then there's the "little children" that don't hear what they want, so they throw a tantrum.

Grow up!

I'm sure Amazon is very happy with this situation. Very happy indeed.
