Slime question?

Decided to add a puncture resistant liner to my Aventon Pace 500 tires, and carry a can of Slime as a back-up. But, when slime is inside the tires, does it plug up the valve stem when checking PSI and/or plug up the hand pump when used??? Slime is cheaper than a liner!

I tend to over-dose my tires with Slime and I don't have those problems. To the extent you do, just wipe it off with a damp cloth. Slime is water soluble.

I agree. Just wipe up any mess. Not that big a deal. My tires likely have a little more than suggested as well. Remembering to check the air with the valve stem located near the top of the rim can help quite a bit.

Check the air with the valve stem located near the top.
I do the opposite!

This is mainly, because I find it easier to press the pump connector on when the tyre is in that position but also because sealant will drain away from the pump connector and back into the tube or tyre.

Clogged valves are easy to clean in water; and, of course, there's always a spare valve core and valve removal tool in the puncture repair kit.

My thought was that you are blowing any Slime up out of the valve when adding air, thus minimizing the potential for a mess, but after reading your idea, I suppose there is some merit to that thought as well. No longer real sure there is a "right" way. Do it any way you like!

Just to verify, if slime is in the tires (mine are 27.5x2.2"), that will NOT affect psi accuracy using a tire gauge, nor will it plug the valve core or the gauge itself?? Since most gauges leak a tad of air when put on the valve stem, why isn't the slime going into the valve core and gauge?

I've never had that problem. When you put Slime in, then you fill the tire, which blows the Slime out of the valve. I suppose if you want to worry about it, you could always put a little air in the tire before you check it, thereby clearing the valve. But like I said, it's never been an issue for me.

I started using slime in my bikes about 5 years ago. NO problems to report in that time span.
Is that a brand name... "Slime" or a generic term? I've just switched to tubeless and the dealer said in his experience the best sealant is now "Finish Line". So I've got that in my tires, but now I see the reviews for that are all over the map, from people raving about it to those who hate it. But I guess I'm stuck now until I need to remove the tire and clean it out. I did find out from the reviews though that the dealer seems to have put in half the recommended amount. So I'll have to buy some of the same stuff and add it, as I'm sure different products couldn't be mixed together.

I'm running Slime. I've had good luck with it to date so no reason to go shopping.... Best of luck!

Yes, Slime is a brand. There are two types, if you want to try it. It comes for tires with tubes and for tubeless tires. Get the right kind for you needs.

I ordered a bottle of Slime without having seen your reply. And just by luck, it's the right one "Tire Sealant" as opposed to "Tube Sealant" that I'd ordered. I don't know if I should chance adding it to my tires which have (not enough, according to the manufacturer) of the Finish Line sealant the dealer installed. Probably not a good idea to mix different sealants. So I'll see if I can buy/order some of the FL sealant just to top the tires up. And then when I have to remove the tires for any reason, I'll clean them out and use Slime next time.

It's funny that when I do a Google search for tire sealants, Slime rarely comes up. And none of the comparison tests I've found compare it. Stan's (regular and race) really does seem to be the most popular followed by an Orange Seal. The Finish Line I've got in my tires is quite low on the review results.

I don't know what to do. According to the Finish Line website, there isn't enough sealant in my tires. I can either buy more of the same stuff and top it up or buy something else entirely and open my tires and clean them before switching. If the reviews for the FL stuff were better, it would be an easy decision, but I'm really tempted to just switch to Stan's Race sealant.

Did I mention that I REALLY don't want to get a flat on my commute? :)

I wonder how Slime compares (real world) with something like Stan's Race.

I think I saw a You Tube comparing a few sealants. I can say there are definitely a lot of strong opinions about brands and even whether any of them are any good.

Flats are almost inevitable if you ride enough. They're nothing to be afraid of. Just make reasonable preparations and take precautions.

To the extent I'd worry about you're situation at all, I'd get more FL when you get around to it, top up, be done.

Thanks for your advice. I'm not afraid of flats :) but I'd rather not have them! In my lifetime I've probably fixed 50+ flats but never (until now) on a bicycle with tubeless tires and rims. I was really surprised at how difficult it was to get the tire off the rim and the tire irons that served me well for many years almost broke. Now I've got a better tool so it'll be easier. But I still prefer not to have a flat, especially now with sealant inside the tire. I am carrying a spare tube just in case, plus latex gloves, but don't carry a rag or paper towels. I'd rather not have to wipe the sealant out before putting in a tube if I'm on the road somewhere.

So right now I just want to do the best job I can with the sealant I have. And your suggestion is really the most logical... just get some more FL and top it up.

Some people claim they've never had a flat, to which I say, "yet". More likely, the normal interval between flats runs from weeks to years, depending largely on what kind of tires they run, the age/miles on the tire and the options they run, like sealant and liners. Trying to avoid flats through best equipment and best practices is obviously the best idea, but another consideration is what setup is easiest to deal with on the road/trail in case you do have a flat. There are a lot of things to consider.

This a good enough reason?, Tyre didn't go flat while the nail was in and after I removed it, and used it for another 18 months after, fitted a new tyre and tube and more slime.
