Criteria for the optimal selection of tractor tyres and agricultural tyres
Choosing the right tractor tyres can seem extensive at first glance – but with a clear set of criteria, it becomes significantly easier. The following six main factors will help you find the right tyres for your machine. In addition, the second part provides valuable tips for selecting suitable tyres for other agricultural equipment. Suppliers like Interpneu AG offer a wide selection of high-quality tyre models to meet your needs.

The six most important selection criteria for tractor tyres
1. Maximum permissible rear tyre diameter
Your tractor's manufacturer determines the maximum usable tyre diameter. This value significantly influences traction, power, and efficiency. Therefore, use the largest permissible diameter to fully utilise your tractor's potential.
Typical sizes for a maximum diameter of 1.95 m include: 650/65 R42, 710/60 R42, or 710/70 R38.
2. The right tyre width
The optimal tyre width largely depends on the application:
- Narrow tyres – ideal for working in tight crop rows, such as with a field sprayer
- Medium widths – suitable for mixed applications like ploughing
- Wide tyres – maximum soil protection and best traction in the field
3. Load capacity and speed index
The load capacity must match the weight of the tractor and the attached implements. Equally important is the correct speed index – especially for machines that regularly operate on public roads.
4. Selection of suitable tyre technology
Technologies such as IF (Increased Flexion) or VF (Very High Flexion) allow driving with reduced air pressure. This protects the soil, improves traction, and increases driving comfort. Depending on the application, it is worthwhile to choose these advanced tyre technologies.
5. The optimal tread pattern
The tread pattern should be adapted to your primary application area:
- Predominantly road: Fuel-efficient road tread
- Mixed use: Versatile all-round tread
- Pure field work: Classic agricultural tractor tread for maximum traction
6. Correct lead (fore-run) for four-wheel drive tractors
For four-wheel drive tractors, front and rear tyres must be perfectly matched. The lead should be in the range of 0–5%. If the tyre diameter is changed, it may be necessary to adjust the front tyres accordingly.
An incorrect lead can lead to increased tyre wear, higher fuel consumption, and damage to the drivetrain.
Tyre selection for other agricultural machinery
Most of the above criteria can also be applied to other agricultural equipment, such as:
- Combine harvesters
- Transport trailers
- Field sprayers
- Self-propelled fertiliser spreaders
- Other special machines
Only the "lead" point is omitted – this applies exclusively to four-wheel drive tractors.
Once you have checked these criteria, nothing stands in the way of optimal tyres for your machines. Interpneu AG supports you with a wide selection of modern, high-performance tyres for every application.
