Benefits and application
This tyre + tube set is ideal for wheelbarrows that are regularly loaded with materials such as soil, sand, construction debris or garden waste. The load capacity of 160 kg and the load index 44 ensure safe use within the intended application range. The TT tyre type (with tube) in combination with the JS87 valve allows for easy mounting and maintenance.
The S-2202 tread pattern offers good stability and smooth running at low speeds up to a maximum of 15 km/h (SI A3). With its 4PR construction, the tyre is resistant to punctures and damage in typical construction site and garden environments. Thanks to the compact dimensions (diameter 272 mm, width 84 mm, rim diameter 4 inch), the tyre fits many common wheelbarrow rims for professional and DIY use.
Explanation of technical terms
- TT (Tube Type): Tyre construction that must always be used with a separate inner tube.
- PR (Ply Rating): Indicates the load capacity class of the carcass. Higher PR values mean a more robust, higher load-bearing tyre structure.
- LI (Load Index): Code number for the maximum permissible load capacity of the tyre at the correct air pressure (here LI 44 = 160 kg).
- SI (Speed Index): Indicates the maximum permissible operating speed of the tyre (here A3 = 15 km/h).
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.
