Benefits and application
This NaRubb tyre + tube is ideal for wheelbarrows, transport carts and similar applications where reliability and load capacity are essential. The S-2201 tread pattern provides good grip on typical surfaces such as yards, construction sites or garden paths. The 4PR carcass rating ensures a reinforced structure and thus increased resistance to punctures and damage.
With a load index 44 and a load capacity of 160 kg, the tyre is particularly suitable for transporting bulk materials, building materials or garden waste. The permitted tyre pressure of 3.4 bar and the maximum speed of 15 km/h are optimally matched to use on wheelbarrows and slow transport equipment. The JS87 valve makes it easier to inflate the tube and is common and proven in industrial use.
Explanation of technical terms
- TT (Tube Type): Indicates a tyre that is used with a separate inner tube. In contrast, TL (Tubeless) stands for tubeless tyres.
- PR (Ply Rating): Indicates the load capacity class of the carcass. A higher PR value (here 4PR) means a more robust, higher-load tyre structure.
- LI (Load Index): Load index 44 stands for the maximum permissible load capacity of the tyre – here 160 kg.
- SI (Speed Index): Speed index A3 indicates the maximum permissible speed. A3 corresponds to 15 km/h, suitable for slow vehicles such as wheelbarrows and transport carts.
- Inch size: Refers to the approximate rim diameter in inches on which the tyre is mounted – here 4 inch.
- Valve type JS87: Special angled valve frequently used on wheelbarrow and small tyres, allowing convenient inflation.
Frequently asked questions about this product
Age: Trailer tyres age more as a result of being left stationary than from the number of kilometres travelled. It is advisable to replace them after around six years, even if the tread is still in good condition; for trailers approved for 100 km/h, this is mandatory. The date of manufacture is shown as a DOT number on the sidewall: 3223 means the 32nd calendar week of 2023.
Load capacity (Load Index, LI): The number before the letter indicates the load capacity per tyre. The fitted tyre must meet at least the value stated in the vehicle documents — a higher value is permitted, but a lower one is not.

Speed index: The letter following the load index indicates the maximum permitted speed. An ‘L’ is required for a 100 km/h rating.
| Index | km/h | Index | km/h | Index | km/h |
|---|---|---|---|---|---|
| J | 100 | M | 130 | Q | 160 |
| K | 110 | N | 140 | R | 170 |
| L | 120 | P | 150 | H | 180 |
Winter tyres: There is no requirement for winter tyres on trailers, as the wheels are not driven. An M+S or Alpine symbol is not required.
Tyre pressure: Trailer tyres require significantly higher pressure than car tyres. The correct pressure is specified in the vehicle documents or on the sticker on the trailer. Insufficient pressure is the most common cause of tyre damage.
Tread depth: the legal minimum is 1.6 mm. You can also recognise old tyres by fine cracks in the sidewall and tread base.
Replacement: Tyres and complete wheels.
