What makes TM800 PowerFlex different from standard tractor tires, and what is VF-PFO construction?

TM800 PowerFlex uses VF-PFO (Very High Flexion - Pressure Field Operations) construction, which allows it to carry up to 40% higher load than standard technology at the same inflation pressure, or operate at up to 0.35 bar lower pressure during field work. In a direct example from Trelleborg's technical data, a 650/65R38 carrying 5,440 kg at 10 km/h requires 1.3 bar in standard technology, 1.2 bar in VF, and only 1.0 bar in VF-PFO. This lower operating pressure extends the tire's footprint, reduces soil compaction, and improves traction without increasing the physical dimensions of the tire.

What traction and field efficiency advantages does TM800 PowerFlex offer?

In field tests at size 650/65R38 (VF-PFO at 1.0 bar, total load 10,000 kg, 16% soil moisture), TM800 PowerFlex delivered up to 17% more traction versus premium competitors in the typical 5 to 15% slip range. In plowing efficiency, it completed 1.30 ha/h versus 1.14 ha/h for a premium competitor and 1.10 ha/h for a second premium competitor, which translates to 14 to 17% more hectares covered per hour. Its footprint at size VF 650/65R38 (3,000 kg load) is also 5 to 9% larger than premium competitor tires, spreading load more evenly and reducing soil stress.

What is the central rib on TM800 PowerFlex and why does it matter?

The central rib is a design feature borrowed from road tire geometry that is specific to the PowerFlex. It improves stability, steering precision, and driving comfort during transport. In road tests, TM800 PowerFlex showed 5% better handling and 10% better driving comfort versus a premium competitor, with 6% lower rolling resistance and up to 20% extended tire life. This makes it a genuine dual-purpose tire, not just a field tire that is tolerable on the road.

How does TM800 PowerFlex compare to TM800 and TM1000?

The standard TM800 uses ProgressiveTraction® lug design without the VF-PFO casing advantage. TM800 PowerFlex adds VF-PFO construction for lower field pressure and higher load capacity, plus the central rib for better road handling. TM1000 ProgressiveTraction® focuses on low rolling resistance for fuel efficiency on the road. If your work mixes heavy field operations with regular road transport, TM800 PowerFlex is the most balanced option of the three.

What sizes are available for TM800 PowerFlex, and how do I maintain them?

TM800 PowerFlex is available in VF-PFO construction across six sizes: VF 480/65R28, VF 540/65R28, VF 600/65R28, VF 600/65R38, VF 650/65R38, and VF 710/70R38. For maintenance, inspect regularly for cuts and sidewall damage, always set inflation pressure according to Trelleborg's VF-PFO pressure tables for your specific size and load (not a fixed figure), and avoid harsh torque inputs that accelerate tread wear. For storage, keep tires upright in a cool, dry, shaded area away from sunlight, ozone, and chemicals.

TM800 PowerFlex

TM800 PowerFlex: maximum performance, anywhere.

Designed for today’s high-power tractors operating under intense conditions, the TM800 PowerFlex combines outstanding field performance with excellent on-road behavior.

Its newly developed tread pattern - which incorporates the proven ProgressiveTraction® lug design - works in synergy with the advanced VF-PFO construction to deliver superior traction, reduced soil compaction, and lower fuel consumption during demanding agricultural operations.

At the same time, the inclusion of a central rib inspired by road tire geometry enhances stability, steering precision, and ride comfort during transport. The result is a high efficiency tire that performs exceptionally in all working conditions, from field to road.

Available Tires Sizes:
650/65R38 | 540/65R28
