flat prevention

Definitely recommend the kevlar liners and puncture resistant tubes; the both work.

I've dug broken glass out of my tires; but, no flat. And on the tubes I have been buying the
'puncture resistant' tubes from Performance Bike.

On the two road bikes I only have the 'puncture resistant' tubes, they are thick rubber tubes. On my
touring bike I have the kevlar and puncture resistant tubes.

The neat thing about the punture resistant tubes, is if you put just the least amount of air in
them, when mounting the tire back onto the rim, it will not get caught between the tire and rim;
which means you don't create flats when changing flats.

Good luck.

I have been getting a ridiculous amount of flats on my mountain bike in the last couple of months.
I ride about 15 miles a day on road and trail. I finally purchased new tires last month and have
since gotten 3 more flats. All the flats except one were on parts on the tube that did not come in
contact with the rim.

I can't believe this since I have ridden over the same trails and roads for 1000's of miles
without any flats.

I am thinking of getting heavy duty tubes, slime tubes or maybe a Kevlar liner. I have heard good
and bad about both slime tubes and Kevlar liners.

I have to try something. I'm getting very frustrated.

What would be the best way to reduce the incidents of flats and keep what little sanity I
have left?

Thanks

I tried kevlar liners and they wore slices in the tubes within a month (from the tube sliding inside
the tire against the edges of the kevlar). But, I didn't have a single flat during that month 🙂.
They also changed the tire profile making it square. Took some getting used to on corners.

I've also seen slime cause more problems than it saves -- a slimed hole is really hard to patch --
the patches don't want to stick. But, many here swear by them, so I probably just had bad luck.

Personally, I'd try the puncture resistant tubes 1st.

I have no personal data on slime tubes on an MTB, but I've seen only marginal benefit in other
applications.

Heavy-duty tubes can help with some types of puncture; nothing will stop some types of debris,
though. have you been able to recover the offending objects and examine them? Their nature should
provide insight into the probability of any given anti-flat method's success.

Kevlar liners reportedly help, but I haven't tried them. At least one acquaintance swears by them,
and I have come to trust his opinions.

One last note: If the punctures are appearing in the tube without a matching hole in the tire, try
running your tire pressure up 5 to 10 pounds. You may just be getting pinches on rock hits.
