I am using kenda 1.95 tubes in a 2.25 tyre. I was told this was OK. The tyres are rated at 40-60 PSI. I am running the rear at 40 and the front at 30-35. NO problems...until this morning.
I checked pressure front and rear and went for a moderate ride....but bumpy.
Suddenly that unwritable sort of "wubbling" sound, followed by unprintable words spoken.
Flat.
I re-pumped, and checked to see it was not just the valve from when I had pumped up earlier.....nah!
I was not far from home so rather than repair in the rain on the wet leaves, I walked back home.
The tube has split on the seam next to the rim tape. There is no sign of wear, or puncture. The seam has simply opened up over a length of about 1/2-3/4 inch (12-20 mm). It does not even show until you either pump up the tube quite a bit, or pull it apart.
I have repaired it to see what happens.
Crappy tube (stock with bike)?
Tube too small?
[censored] happens?
Thanks for any advice.
