Which size innertube for the the ASW15?

[MartinH]

Hi everyone - as a proud new part-owner of a lovely ASW15 (nr 15042) one of the first jobs we have to do is to fix a flat tyre which is due to a slow leak. I've changed the valve, but if that doesn't fix it then the problem will be with the innertube. I can't find a reference to the tyre size in the manual, and I could not see any helpful markings on the tyre itself. Does anyone have any advice about the correct size innertube to fit, and where I could source one (I'm in the UK)? Thank you.

There is a difference in wheel size in the (a) and B version. As far as I know the B has the same tube as the ASK 13. I can't help you with the (a) version.

Hi Martin,

if I am right ASW15 has a 4.00-4 and ASW15B a 5.00-5 tyre.

So I think this inner tube should fit for your ASW15 (as they write in their item description)

If you do not find a dealer in the UK maybe it would be a solution to buy there.

Hi Marcus, and thanks for the advice.  It is indeed a 4.00-4 inner tube on the ASW15. I managed to source one of these in the UK from Watts aviation for £16 including postage.
