Nokian Tyres has extended its Soil King VF agricultural tire range for 2026 with four additional sizes designed specifically for high horsepower tractors operating in heavy, moisture sensitive soils. The new additions include VF600/65R28, VF710/70R38, VF710/60R42, and VF710/60R34, bringing the total lineup to 17 sizes and strengthening coverage across mid and high power tractor segments.
New Soil King VF Sizes Expand Coverage for Modern Tractor Setups
The newly introduced sizes target tractors in the mid to high horsepower category, particularly those used in tillage and heavy draft operations. With VF construction, these tires maintain load capacity at lower pressures, improving field performance and reducing soil impact.
Flexforce VF Technology Improves Traction While Protecting Soil Structure
Nokian’s Flexforce VF technology allows the tire to operate at significantly lower inflation pressures compared to standard radials. This increases the footprint and reduces ground pressure, which directly minimizes soil compaction.
In practical field conditions, this results in:
- reduced slip under load;
- improved traction in wet and clay soils;
- lower fuel consumption.
This makes the Soil King VF particularly relevant for conservation farming systems and operations where soil health is a long term priority.
Verified Field Performance Backed by DLG Testing
Independent testing by DLG confirmed measurable improvements in traction efficiency, fuel consumption, and work rate. Lower slip and better power transfer allow operators to cover more hectares per hour while reducing operational costs.
Intuitu 2.0 Smart Pressure System Brings Real Time Optimization
The Soil King VF line integrates Nokian’s Intuitu 2.0 Smart Pressure Assistant, a sensor based system embedded in the tire.
It actively calculates optimal tire pressure based on real time load and working conditions and sends recommendations directly to the operator’s smartphone. This goes beyond traditional monitoring by providing actionable adjustments during operation.
The system received a Silver Medal at the Agritechnica Innovation Award 2025, confirming its relevance in modern precision farming workflows.
Key Technical Specs Highlight Real World Performance Focus
Available specifications from the new range confirm the tire’s positioning as a heavy duty field solution:
- tread depth around 55 mm for strong traction in soft soils;
- tire width up to approximately 710 mm for increased footprint;
- rolling circumference exceeding 4.5 meters on larger sizes;
- speed index up to 65 km/h depending on configuration;
- maximum inflation pressure around 280 kPa.
These parameters reflect a balance between field traction, load capacity, and transport efficiency.
