Our new Profi-Grip wheels feature a unique profile, developed to eliminate tyre-to-rim slippage. Featuring a strong flange which both minimises rim shrinkage, and serves to protect the tyre when used at low pressure, the Profi-Grip wheel also incorporates our unique Profi-Fit TW design, which allows high-load capacity tyres, with very stiff sidewalls, to be mounted easily and with no risk of tyre damage.
Featuring a unique profile designed to eliminate tyre-to-rim slippage, Profi-Grip was launched specifically to meet the growing demand from ever-larger and more-powerful tractors.
The new design of the wheel rim features a strong flange which both minimises rim-shrinkage and serves to protect the tyre when used at low pressure. The Profi-Grip wheel also incorporates GKN Wheel’s unique Profi-Fit TW design, which allows high-load capacity tyres, with very stiff sidewalls, to be mounted easily and with no risk of tyre damage.
Designed to ETRTO (European Tyre and Rim Technical Organisation) standards, the Profi-Grip wheel has been developed to deliver significantly improved contact pressure between the tyre and rim - which not only eliminates slippage but also makes the fitting of high-load capacity tyres faster and more straightforward and provides enhanced durability. Extensive tests, both on-track and in-field, have confirmed that the rim design completely eliminates tyre slippage
Outlining the thinking behind the new product, Ole Dall, GKN’s Product Manager, Wheels, said: “Tyre slippage has become increasingly problematic over recent years. The combination of larger tractors, increased horsepower, larger implement machinery, low inflation pressure with Central Tyre Inflation systems (CTIS), and heavy loads is causing tyre slippage. Tyre manufacturers are developing tyres to run at a low inflation pressure to maximise the “footprint” and the transfer of power from the tractor to the soil.
“However, an inevitable consequence of this is that the interaction between the tyre and rim is being compromised, particularly when operating in dry soil conditions, with tyre slippage often being the result. The new Profi-Grip rim profile has been developed specifically to address this problem.”
Profi-Grip delivers benefits in wet and heavy conditions during the winter, but it is increasingly proving its value in the extremely dry conditions seen during summer months in some regions - where the issues of traction and tyre slippage are equally problematic.
