Flat:Split seam

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?
Shit happens?

Thanks for any advice.

You used a KENDA!! :eek:

Nic, go the extra $ and get Conti with presta valves. :)

If you want some cheap tyres and tubes come and see me. :D http://perthmtb.com//modules.php?name=Forums&file=viewtopic&t=1605 Some of these are off new bikes.

OK. Crappy tube then :)

I didn't exactly _use_ it. I simply _re_used it :) It was on the bike.

However I take your point. I have spares (not Conti. I will check that out) that certainly look better on the seams, with a slight ridge, where the Kenda has a simple butt joint.

Anyway, apart from the bad reuse of the Kenda, it's nothing I have done.

Most unfair. It was such a good ride and I was just getting rid of a bit of steam! Bah!:(
