Multiple flat tires on front My new bike is a Giant LaFree (electric pedal assist) with 26 x 2.35 tires. The tires are CST Metropolitan Palmbay.
I have had multiple flats on the front. The leak is always on the inside of the tube in the same place, where the ribs are.
My bike shop sells me Sunlite 26 x 1.95 - 2.125 tubes. I have changed the inner rim strips to cloth ones, I run the tires at 60 psi (recommended on the sidewall is 22 - 60 psi).
I'm not sure what to try next.
Thanks very much,
Robert
The Sunlight tubes I was using have a &quot;ribbed&quot; area near the valve stem. Patches just did not hold in that ribbed area.
Inside the rim no sharp areas or spokes protruding, but I added an additional cloth rim strip and a Continental brand tube purchased from a different shop.
It is holding for now, although this problem sometimes doesn't show up immediately.
Here's hoping it is a good fix.

(later) I am happy to report that changing to a different brand of tube (continental) and adding a second rim strip has solved my problem of multiple flat tires.
