Profi-Fit Wheels

GKN’s innovative Profi-fit Wheel is the perfect solution for low pressure agricultural tire applications around the world. Designed by a global team of GKN Wheels and Structures’ engineers, the wheel combines durability with reduced weight and easier tire fitting, bringing benefits for both original equipment manufacturers and end users. Low pressure tires are extensively used in agricultural applications in order to minimise the risk of soil compaction. However, these tires typically have stiffer walls, making them more difficult to fit. GKN developed Profi-fit specifically to address this problem. Detailed research has been undertaken using Finite Element Analysis and acquisition of stress data by use of strain gauged wheels. This has enabled GKN to develop a more structurally efficient rim profile with a 10% weight saving, while still achieving a 40% stress reduction in critical areas. The Profi-fit Wheel has a rolled over flange which improves rim strength and minimises the risk of tire damage during fitting. It also has a specially angled section, more than double the TRA/ETRTO minimum of 15°. This greatly improves ease of tire bead seating during inflation and allows tires to be fitted at pressures below 2 bar. Incorporation of a unique ‘double bump’ radius design at a critical point where traditional rims are susceptible to ultimate fatigue failure reduces stress, whilst maintaining strength and performance. The lower weight reduces vehicle group pressure and contributes to savings in fuel consumption and carbon emissions. The typical application for a Profi-fit rim includes combines, self-propelled forage harvesters and tractors. It is produced in the UK, Denmark, the USA and Italy.
