Schwalbe Air Plus Tube Nr. 19-AP – Less Pumping, More Riding on 28"/29" Wheels

Whether you’re commuting on a 28" trekking bike or hammering trails on a 29er, the Schwalbe Air Plus Nr. 19-AP is the inner tube that quietly does its job better than anything standard. Made with a high proportion of pure butyl rubber and walls approximately 70% thicker than a conventional tube, it holds air significantly longer and resists punctures and pinch flats with ease. Fit it, inflate it, and get on with riding — that’s the Air Plus way.

This version uses an AV (Auto Valve / Schrader) valve with a 40 mm stem — the same type found on car tyres, compatible with virtually any pump or petrol station compressor. It fits tyres from 40 to 62 mm wide (ETRTO 40/62-622), covering a wide range of 28" and 29" applications from road to trail. And like all Schwalbe tubes, it is 100% recyclable.

Frequently Asked Questions

Is this tube compatible with both 28" and 29" wheels?

Yes — 28" and 29" wheels share the same ETRTO rim diameter of 622 mm. The difference is in tyre width and marketing convention: 28" is typically used for trekking and city bikes, while 29" refers to mountain bike wheels. This tube (ETRTO 40/62-622) fits both, as long as your tyre width falls between 40 and 62 mm.

What valve type does this tube use?

The Nr. 19-AP uses an AV (Auto Valve / Schrader) valve with a 40 mm stem. This is the same valve type found on car tyres and is compatible with most standard floor pumps, hand pumps, and petrol station air compressors. No special pump head is required.

What makes the Air Plus better than a standard tube?

The Air Plus is made with a higher proportion of pure butyl rubber and has walls approximately 70% thicker than a standard tube. This results in significantly better air retention (you pump up less often) and above-average resistance to punctures and pinch flats.

What tyre widths is this tube compatible with?

This tube fits tyres between 40 and 62 mm wide (ETRTO 40/62-622). This covers a wide range of 28" trekking tyres and 29" MTB tyres. Always check your tyre’s ETRTO width before ordering.

Is this tube compatible with e-bikes?

Yes — the Air Plus tube is suitable for use in e-bike tyres within the compatible size range (28"/29", 40–62mm). Its thicker walls make it a particularly good choice for heavier e-bikes where puncture resistance is important.

Is the Schwalbe Air Plus tube recyclable?

Yes — like all Schwalbe tubes, the Air Plus Nr. 19-AP is 100% recyclable. Schwalbe runs a tube recycling programme, so when your tube reaches the end of its life, it can be returned for recycling rather than going to landfill.
