Tubes(17 posts)

I want to know which tube you have had the best luck avoiding flats? I am running Mich Axial Pro's. Weigh approx. 200#. I have had a bad run of 6 flats in a 3 week period. All on the front wheel. Have looked for burrs on my Kysyrium wheel, could find none. Your suggestions would be appreciated.
Shoot, you call two flats a week a LOT?Flatman

That's about standard around here in the land of the Big Thorns... Seriously, two years ago I kept track, loosely, and averaged about a flat every 30 miles, even with Kevlar belted tires.
FWIW, I've had the best luck with Continental tubes, when I can find them, but it's not such a huge difference that I won't buy anything else. Where are the holes in the tubes? If they're on the surface next to the tire tread, check to be sure you haven't left a piece of thorn or something sticking in the tire. Sounds like you've eliminated rim problems, but what about spokes? Check the rim strips or tape, and make sure a spoke's not protruding inside. And if you're getting snakebites (matching holes on each side, also called pinch flats), add a few pounds of air (sorry if you know all this, but some people don't and it might be helpful).

I've had great success with these, and like 'em better than the ones from Slime because they don't ooze at the valve. They self-seal small pinpricks (like thorns) very very well.

As much as I hate the idea of heavy tires or tire liners, if I were commuting I'd buy a set of Armadillos or put tire liners in a road bike in a heart beat.

Ditto on the suggestion that you need to evaluate the tubes to see if the damage keeps recurring in the same spot, which would indicate either a rim strip problem (if on the inside) or something wedged in the tread (if on the outside).

Good luck.

I've been averaging one flat per year or 2000 miles. Most of the flats have been from defective tubes, and a few from goatheads. I like Performance Ultra Lite tubes, it's about the only thing I buy from them. All of my rims have Velox rim strips, I won't ride without it. I do not roll my bike through grass or weeds, period. I ride Michelin Axial Pro's mostly, also Vredestein Fortezza's and Continental Grand Prix 3000. Like the Axial Pro's best, at 118psi. I weigh 165 (in the summer).

Check for (tiny) shards of glass/metal/thorns hiding in the tread. Had one of those for a week or two. Tracked it down by aligning the labels with the stem the same way every time, and then checking the area where the flat was forming. Sure enuf, deep in the tread was a tiny glass sliver hiding in the tread. Flexing the tread at just the right spot showed the tiny hole it was buried in.

Being anal about the position of the labels does help once in a while.

Try double butted tubes, they are supposed to be stronger but lighter.

First problem is the axial pros, very fast, very soft. Get rid of these for training, they are race only tires. I love these tires but to train on them is a crime. Save them for raceday.I ride Conti gatorskins fitted with slime tubes for training. Where I like there is alot of glass on the road because no one seems to clean up after car accidents, and the glass recyclers seem to enjoying dropping half of what they are surposed to be recycling on the road.

Personally, my favorite Tube is Fee Waybill :)

Sorry, Jim, must I must point out that some of us get incredible performance out of these Michelin Axial Pros. I am not a racer, but I ride lots of centuries, and the performance I get is superb. I rarely get flats though I ride in all kinds of conditions. I've never had a tire perform so well.

I am not knocking the performance of axial pro's. They are the most adhesive tires I have ridden and are especial good in crits. What I am saying is that they are soft, and if you live in an area that is prone to glass, thorns, and other crap on the roads I think that you are better off on a harder compound tire with reinforced kevlar belting.

I get lots of miles out of Axial Pros (2,000+ miles) and about one flat per year, or 6,000 miles. I think a lot depends on road conditions. Apparently the roads in NC are better than many places. And thorns -- what are those? Are you guys riding through blackberry patches?

These goatheads seem to be prevalent from Oklahoma to the West Coast. People laugh at me for carrying my bike from my vehicle to the road, and up to the registration table, and through the rest stops, but I get the last laugh as I roll by and they're sitting on the side of the road changing flats.

Front wheel flats are rare. If you are getting repeated front wheel flats, I think you have a problem that you haven't resolved that is causing them.

Examine one of your flat inner tubes. Pump it up to see where the hole is. I'm betting its on the inside circumference of the tube. If so, check your rim strip all the way around. The plastic rim strips that come on lots of new wheels, I have to use a technical term here, SUCK. If you find a place where the rim strip doesn't cover every little bit of a spoke hole, throw the rim strip away and replace it with new Velox rim tape.

If the hole is on the outside circumference of the tube, you have a thorn or a bit of glass in your tire that keeps puncturing your expensive, new innertubes. If you can't find it, throw the tire away and buy a new one. It will be worth it's price for the aggrivation is saves you.

Good luck.

I found a sharp burr on the rim, which was not protected by the rim strip. This came by examining the tubes, the holes were virtually in the same spot. Thanx.
Nice try, but Ksyriums have no rim strips!look271

I'd bet he has a piece of something still in the tire. This happened to me with my commuter, which never gets flats. A piece of glass had gotten into the tire (I thought that I had removed all of it, but NOOOOOOOOOO!) There it was, just barely piercing the inside of the tire. It was a real mother to get out!
Oops! Glad you found it! (nm)look271
