Slime Tubes

I bought two Slime tubes and one new tire. I couldn't get the exact tires I wanted. They were either out of stock or didn't have my size. So I compromised and got a reguar Elecony mountain bike tire with 600 TPI vs 300 TPI (threads per inch) for $27. I had one tire worn pretty smooth, and I got 5 flats in one week so something had to give. I've only had this configuration a short time now, but so far no flats.

I've looked at tire inserts, tubes, liners, tires you name it. My neighbor told me he used to cut up old tubes and line his tires with those. Said it worked OK.

I'd be interested in hearing from anybody else who has any experience with these kinds of products, especially the Slime Tubes. They were only $7 apiece on Amazon.

My experience with Slime Tubes is that they did very little to seal punctures but once in a while they worked. Trying to patch a leaking Slime filled tube on the road was nearly impossible as well as the slime prevented any vulcanizing fluid from bonding properly. Could be done at home with some good cleaning and careful handling of the tube to prevent the Slime from coming out but can be done. Using old tubes as tire protection seems to have only minor success as well and dedicated plastic tire strips are a little better. The best way to prevent flats is to have a good tire with a thick carcass and some puncture resistant belts molded into the tire. This of course can make a heavier and less supple ride if that matters but at least you keep rolling.

Are you determining why every flat happened? If you don't verify that every flat was an actual tread punctures from road debris, then you might be just chasing for puncture resistant tires and tubes that won't be much help at all.

Slime tubes suck !
Just had to replace one in the shop...freakin' green goo all over the inside of the tire and of course I had to clean it out to do the repair/replacement correctly...ick what a mess.

95% of my flats come from thorns.

If thorns then I'll leave the suggestions to others. I don't live where thorns are an issue and all my riding is on paved roads. So maybe someone with some Mtn bike experience will no more about those other products you ask about. Have you considered tubeless?

However when my tires go thin and are showing threads or very close to that, then flats are expected. Once I get the first flat at that point in the tires life I replace it.

Do you have Goat Heads?



They're just nasty.

I'm not sure if there is any single solution to them. Certainly picking them out of the tires every once in a while helps. Get the stickers out too. If you've gotten several flats in a week, it is possible you missed some thorns.

There are a couple of solutions that people have tried. One option is to use tires with a thick absorption layer, so it is less likely a thorn will stick all the way into the tire.

Schwalbe Marathon Plus
Michelin Protek Cross Max



Tire liners may also help.

I only ride on paved roads, but these goat head thorns and Acacia Tree thorns can blow in from the undeveloped areas, or wherever they plant the Acacia Trees. There is a stand of them right by my house. The Acacia Tree thorns can range from 1/8 inch to 2 inches long. Check out these photos.

No slime tubes and certainly no whatever no-name tires those are, that is not a brand I have heard of or would use. Schwalbe tires level 5 or 6 and standard butyl tubes also from Schwalbe, Continental, Specialized....(good quality) would be my go to with a fresh rim strip and burr free rim and proper pressure. If I needed more protection I would use Tannus Armour liners which are a lovely foam insert for the tire which will likely prevent little thorns and goat heads from getting to the tubes.

I don't want goo in my tubes they are messy and don't work and any mechanic is going to hate you for it. Tubeless isn't so bad, it is still messy but no more pinch flats and likelihood of fewer issues of punctures as hopefully the sealant will do its job and seal the little hole.

Continental Super Sport Plus are of similar design to the Schwalbes with the puncture belt listed above, but I think they use a denser, thinner belt. They're somewhat less usually than Gatorskins, IMO at leas as puncture resistant, and quite long wearing.

I live in an area where there tends to be a fair amount of small (and generally not visible) bits of road debris that often punctures tires - e.g., wire bits from tire blow-outs, staples, small (and not so small sometimes) nails, etc . . . . Before I started using the Super Sport Plus, I'd get punctures regularly - sometimes more than once weekly. With the Super Sport Plus, very rarely. I can think of 2, and both of those were from oldish nails that visually blended into the road surface that might have caused a flat (or at least a slow leak) on a car tire.

Best I can recall, the Super Sport Plus is available in both Kevlar- and wire-bead versions. The latter can be tough to install - but I've had folding bead tires (Conti Ultra Sports) that were as hard if not harder. They're available in 700c-23, -25, and -28, but the last can be hard to find.

I've also used tire liners when I didn't have a Gatorskin or Super Sport Plus handy. Those seem to work about the same.

Neither solution is low-rolling-resistance, so you'll give up a bit there. But I don't do tubeless - and I'd have a bit lower average speed than spend 20 min on the side of the road changing a flat.

I've never changed a flat on the road. How do you find the leak?

Finding the leak in the old tube is usually easy - just remove the old tube and inflate it somewhat with your frame pump, then look/feel to see where it's leaking. I've always been able to find such a puncture without having to immerse the tire. I also mount tires with the label diametrically opposite to the valve hole. That plus the location of the puncture tells me where to focus the search for embedded debris in the tire. But I generally check the entire inside of the tire, just to be sure.

I carry a spare tube in a small seat bag when I ride. After checking the interior of the tire with a finger (very carefully) to find whatever punctured the tube if it's still embedded in the tire, I then remove anything embedded in the tire and put in the new tube.

Often the location of embedded debris is visually obvious. But if it's not, careful and gentle rubbing with a finger will usually find whatever it was that caused the puncture if it's still embedded. (It can also provide a small blood sacrifice to the tire "gods" if you're careless or work too fast because you're impatient. )

I then carry the dead tube home and make a "patch or pitch" decision. I get puncture flats so infrequently these days it's almost always "pitch".
