Benefits and applications
This tyre with tube is ideal for light tractors, walk-behind tractors, compact tractors or attachments used in gardening and landscaping. The S-2301 tread provides reliable traction on grass, soil and gravel without excessively damaging the ground. The 2PR version is suitable for applications with moderate loads up to 150 kg per wheel and low driving speeds up to 15 km/h.
The combination of tyre and matching tube (TT system) ensures easy mounting and a secure fit on the rim. The TR13 valve is widely used and fits many standard rims in the agricultural and garden segment. This makes the set a reliable choice for maintenance, replacement or original equipment of your agricultural and horticultural machinery.
Explanation of technical terms
- TT (Tube Type): Tyre is used with a separate tube.
- PR (Ply Rating): Indicates the load capacity class of the carcass; higher PR values generally mean higher load capacity.
- LI (Load Index): Numerical code for the maximum permissible load capacity of the tyre at nominal pressure (here LI 42 = 150 kg).
- SI (Speed Index): Letter code for the maximum permissible speed (A3 = up to 15 km/h).
- Valve type TR13: Common straight tube valve for many agricultural and industrial applications.
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.
