Hi all,

I've been getting repeated flats lately. Can anyone recommend a good inner tube to minimise this occurrence?

Tyre size = 16 inch x 2.125

Thanks

Is there something sharp stuck in the tyre that is puncturing the inner tubes (feel inside of tyre with fingertips). Don't think different inner tubes will help. Are you using a puncture resistant tyre ?

Change the tyre! Fit a Marathon Plus with a new tube, and unless you run over a big drawing pin as I did this week, you will wear the tyre out before you get a flat.

Repeated flats mean another problem: hedge clippings? Pinch flat from low tyre pressure? Glass on the road?

Or with single wall rims, check if nipples are wearing through due to a not good enough rim tape. Occasionally the valve hole gets a rough edge and makes a hole right there.

There was a hole in the tire, which I think was due to a lot of glass on the roads recently. I'll seek out some Marathon Plus ones. Thanks for the input
