The tyre on my bike

Can anyone tell me what spec inner tube I need for this tyre? I discovered the one I'd previously bought didn't look fat enough when I got my first puncture with it the other day, now I'm in the process of getting the kit I need to quickly fix punctures on the way to work.

Thanks very much! John.

Is there a metric equivalent? Finding one for my road bike was easy but this seems to be a weird tyre.. –  John Hunt Mar 7 '13 at 9:27
    
Keep in mind that tubes can cover a fairly wide range of tires. The same tube generally fits 27" and 700 (28") tires, and typically a width range will be speced something like 28-37 mm. –  Daniel R Hicks Mar 7 '13 at 12:53

Looks like 28 x 1 3/8 (although I did have to squint a bit!), or 700 x 35 if you prefer metric. I think they're pretty standard, I seem to remember having a hybrid that had this size wheel.

For example, the first result on a google search shows one on Amazon. That particular one is a Kenda but I'd lay odds that all the main manufacturers will make this size.

As regards an on-the-road fix, I carry a repair kit (glue & patches) but to be honest would only use if absolutely necessary. Its pretty cheap, and certainly easier, to carry a spare tube. That plus a couple of levers, plus a small pump or CO2, should get you home. I like to carry some disposable latex gloves as well, just to minimise how mucky I get.

If you start getting regular punctures, look more at what tyres you're riding.

Well it's the first puncture I've had with this bike.. totally agree about having spare tubes.. trying to patch a hole is frustrating, time consuming and mucky. Good idea about the gloves too! –  John Hunt Mar 7 '13 at 11:01
    
Yes, 622 is 700c. As a general rule, it's safer to use the ISO/ERTRO measurement, though it doesn't matter as much for inner tubes as it does for tyres (the wrong "28 inch" tyre won't fit the rim, but a 28" tube will stretch). sheldonbrown.com/tire-sizing.html –  armb Mar 7 '13 at 13:56
