How would you like 260kg more payload on your eight-legger? And I'm talking, mixers, tankers, bulkers too. 'How so Biglorryblog?' I hear you ask. Well I'll tell you now if you stop fidgeting... Goodyear has launched a new 495/45R22.5 Omnitrac MSD super single truck tyre for use in mixed service applications to increase the vehicle's payload capacity."
And here's one I pumped up earlier... The 495/45R22.5 Omnitrac MSD wide drive tyre has been specially-designed for use in mixed service applications. And if you were to use 495/45R22.5 Omnitrac MSD super single truck tyres on alloy rims instead of eight 315/80R22.5 MSD tyres the totral weight saving would be an impressive 260kg.
Goodyear says: "Vehicle types that will typically benefit the most are concrete mixers, bulk transport trucks, and other models where every kilo saved on the empty vehicle is a kilo gained on the payload. Used for the shuttle service in a major building project, the additional 260kg payload offered by the new Goodyear super single drive tyres will reduce substantially the overall number of trips required, and thus the fleet's total cost. Fewer drive cycles will also reduce the overall fuel consumption, reduce CO2 emissions and the overall impact of the construction works too.
Interesingly enough the eidea of wide singles on tippers and mixers is nothing new. I can recall a Leyland Constructor 30.30 eight-legger being punted up for test with Commercial Motor a good 18 years ago with wide singes... They never really caught on. But will they now?

The 495/45R22.5 Omnitrac MSD has a tread design dedicated to the typical needs of the mixed service usage.which combines a high mileage tyre tread with the traction performance and damage resistance of an Omnitrac mixed service tyre. The shape of the grooves and blocks ensures excellent self cleaning properties while the arrangement of the tread blocks provides low noise levels.
The tyre cavity shape is also designed to give a uniform pressure distribution all over the surface in contact with the ground in order to improve the tyre's wear profile and traction performance. The silica tread compound shows an excellent wet performance and its shoulder block bridges ensure robustness in more severe applications as well as good driving stability and handling. Goodyear will offer retreaded tyres to provide the best economical package throughout the complete carcass life. The new Goodyear 495/45R22.5 Omnitrac MSD is also fully regroovable.
Apparently Goodyear says it has "....partnered with Renault Trucks and introduces this new tyre on a dedicated chassis set-up which confirms the industrial interest in this new innovative tyre product."
The tyre's features and benefits are:
§ wide tread for high mileage and excellent traction
§ continuously widening groove width towards shoulder edge for better self-cleaning
§ shoulder block edge offset for better mud traction
§ stiff block design for higher damage prevention
§ optimized pitching sequence for lower noise
§ shoulder humps for improved robustness and handling
§ open tread design with optimized block taper angles to prevent stone picking
§ new tread compound for more mileage and higher tear and cut resistance
§ silica tread compound for an improved wet braking performance
§ multi-radius tread contour for better contact pressure distribution
