Heidenau Inner Tubes — Tubes for Motorcycles, Scooters and Mopeds
A motorcycle inner tube is needed wherever a tube-type (TT) tyre sits on a spoked wheel — which covers almost every classic, enduro and off-road machine. This section brings together Heidenau inner tubes: the part that holds the pressure inside the wheel and decides whether you ride home or patch a puncture on the verge.
Heidenau inner tubes are made from natural rubber. It stretches better than synthetic, hugs the tyre more closely and copes longer with the constant flexing under load — under acceleration and braking the rubber inside the wheel is worked and heated, and cheaper material gives out sooner. The range comes in three types: standard for town and everyday riding, reinforced Cross for long trips and touring-enduro, and Heavy Cross for motocross — the last for off-road only, with no road approval.
A Heidenau tube is chosen on two figures: wheel diameter (from 10 to 21 inches) and tyre width. One tube covers a whole band of widths, so the point is to land within the band rather than match a single number. If your tyre size falls between two tubes, take the wider one — it will not have to over-inflate to reach the tyre.

How to choose a Heidenau inner tube by size
A Heidenau inner tube is chosen on wheel diameter and tyre width, not on a single number. Each tube is rated for a whole band of widths at its diameter — for example, the 18E tube for 18-inch wheels fits tyres from 3.25 to 4.60 and metric sizes from 90/100 to 130/70. If your size falls into two tubes at once, take the wider one: it seats more snugly and will not stretch inside the tyre. Read the width from the marking on the tyre sidewall and the diameter from the wheel's seat diameter (10–21″).
Standard, reinforced Cross or Heavy Cross — what sets them apart
The three Heidenau tube types differ in wall thickness, which in turn sets their puncture resistance and weight. The thicker the wall, the harder the tube is to pierce, but the heavier it is — so the type is matched to riding style.
| Tube type | Wall thickness | Best for |
|---|---|---|
| Standard | 1.5–2.0 mm | Town, road, everyday riding, scooters and mopeds |
| Reinforced (Cross) | 2.5–3.0 mm | Higher loads: long trips, touring-enduro |
| Heavy Cross | 4.0–4.5 mm | Motocross and hard off-road |
Heavy Cross tubes are for off-road use only: they carry no road approval and are not used on public roads.
Straight or angled valve
The valve on Heidenau tubes comes straight or angled — the choice depends on how easy the valve is to reach on your wheel. The straight valve (34G) is the all-round option for most wheels. Angled valves (at 90°, 70° or 86°) help where a pump will not reach a straight one: a brake disc or a deep rim gets in the way. If you are unsure which one you have, check the old tube or send a photo and we will point you to the right one.
Don't forget the rim tape
On a spoked wheel a Heidenau tube lasts longer with an intact rim tape underneath it: the tape covers the spoke heads and the rim edge so they cannot chafe through the tube from the inside. It is worth replacing the tape together with the tube — an old one may have hardened or slipped. Choose a tape in the rim tapes section; the full range sits under Inner Tubes & Rim Tapes.
Frequently asked questions about inner tubes
Can a tube be fitted in a tubeless (TL) tyre?
No. Tubes go only in tube-type tyres marked TT. A tube is not fitted in a tubeless (TL) tyre — it is unsafe. Tube-type wheels are usually the spoked rims on classic, enduro and off-road machines.
What happens if the tube is the wrong size?
A tube that is too wide for a narrow tyre bunches up and eventually tears, while one that is too narrow has to be over-inflated to fill the wheel — and that raises the puncture risk. This is why a Heidenau tube is matched precisely to the tyre's width band.
What are Heidenau tubes made of?
Natural rubber. It is more elastic and more resistant to mechanical loads than synthetic — you notice it in service life and in safety when a foreign object gets into the tyre.
Standard or reinforced tube for enduro?
For touring-enduro and long trips on mixed surfaces, Heidenau offers reinforced Cross tubes with a 2.5–3.0 mm wall — they take knocks better. For genuine motocross, riders choose Heavy Cross (4.0–4.5 mm), but that is off-road only.
