MICHELIN ULTRAFLEX TECHNOLOGY: AG Tire Sidewall

MICHELIN TIRE WITH ULTRAFLEX TECHNOLOGY

Michelin Ultraflex Technology

The technology that has been improving traction and reducing soil compaction for 20 years.

Michelin proudly celebrates its 20th anniversary of its invention of the Ultraflex technology, which was introduced as the Very High Flexion (VF) standard for the first time in the market back in 2004.

Through reinforced sidewalls with high deflection, and special rubber blends, Ultraflex technology provides benefits to farmers with better productivity per acre through greater traction; improved yield through less compaction and increase fuel savings, through less slippage.

Reducing the pressure increases the tire contact patch. This improves your productivity, due to higher tire flotation - giving you the ability to carry heavier loads at lower pressure.

The results showed quite clearly that Michelin Ultraflex Technology tires significantly reduce compaction and, in the process, boost farmers' yields by 4%*.

PRODUCTIVITY

Carry up to 40% (2) more load at the same pressure vs a non Very High Flexion (VF) radial tire in the same size

MICHELIN tires with Ultraflex technology allows operatation at low pressure while carrying more load, at higher speeds* – without damaging your soil.

MICHELIN tires designed with Ultraflex technologies offer better traction, improving field productivity and increases annual work efficiency by up to 4%.(1)

Michelin has you covered during every stage of the crop cycle with our complete and durable lineup of ag tires featuring MICHELIN UltraFlex technologies for Improved Flexion (IF) and Very High Flexion (VF).

WHAT IS MICHELIN ULTRAFLEX TECHNOLOGY?

Michelin Ultraflex technology allows you to carry heavy loads at low pressure and faster speeds.

What is the secret? An innovative, tough casing that enables more flexion.

The flexible casing construction allows for a larger footprint, increasing tire traction.

With Michelin UltraFlex technologies, improving crop yield starts with your tires.

MICHELIN ULTRAFLEX TECHNOLOGIES: FAQs

WHAT IS CONSIDERED A LOW PRESSURE AG TIRE?

Low pressure tractor tires are tires with reinforced high flexion (HF) sidewalls with special rubber blends that make the casing extremely durable at low pressure. Tires are certified IF (Improved Flexion) or VF (Very High Flexion) reducing pressure from 20% to 40%, vs. standard tires – while supporting same loads(3).

Michelin designed the first low pressure tire (VF) with MICHELIN Ultraflex technology in 2004 with the launch of the MICHELIN XEOBIB.

WHAT ARE THE TIRES THAT INCLUDE MICHELIN ULTRAFLEX TECHNOLOGY FOR AG EQUIPMENT?

• Tractors: MICHELIN EVOBIB, MICHELIN AXIOBIB 2, MICHELIN XEOBIB, MICHELIN YIELDBIB, MICHELIN AXIOBIB

• Harvesters and floaters: MICHELIN CEREXBIB 2, MICHELIN FLOATXBIB, MICHELIN CEREXBIB

• Sprayers: MICHELIN SPRAYBIB CFO, MICHELIN SPRAYBIB, MICHELIN AGRIBIB ROW CROP IF

• Trailers and implements: MICHELIN TRAILXBIB, MICHELIN VF XP27, MICHELIN CARGOXBIB HIGH FLOTATION

Have the benefits on crop yield been tested and certified by an independent organization?

A study carried out by Harper Adams University(1) demonstrates that MICHELIN ULTRAFLEX technology increases agronomic yields by 4% on average due to lower soil compaction, while improving traction and fuel economy. These results are confirmed by similar studies completed in the United States (Illinois) and Brazil (Mato Grosso).

For example: a farm that produces 8 tonnes of wheat per hectare and sells each tonne of wheat for $200 would earn an extra $64 per year per hectare. (based on 4% of additional yield)

HOW WILL LOW PRESSURE TIRES HELP FARMERS PROTECT THEIR SOIL?

Michelin designed low-pressure tires to reduce farming machinery from compacting the soil.

For example, for a 13,271 lb (6,020 kg) load, the MICHELIN AXIOBIB 2 tire would be at 1 bar (15PSI) of pressure while the standard / non VF (Very High Flexion) tire would be at 1.6 bar (23PSI), at 40.39 miles/h (65 km/h) and with a 710/75R42 size.(3)

The higher the pressure, the more the soil is compacted, and we know that soil compaction modifies the structure and chemical composition by removing the macro-pores that foster air and water flow. By altering the mineralization of roots, significant compaction reduces the soil’s yield.
