Goodyear’s LHT II – Low Rolling Resistance Without the Drawbacks?
Newton’s First Law of Motion states that ‘every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it’. For tyres, this external force is seen in rolling resistance, and it is primarily caused by the repeated deformation and recovery of the tyre as it comes into contact with the road surface. Reducing rolling resistance is, in theory anyway, relatively simple – yet achieving a reduction in rolling resistance without compromising on other essential tyre qualities is another matter entirely. In designing its latest generation trailer tyre, the Marathon LHT II, Goodyear referred to this as “mission impossible”. Yet through much research and development work the tyre maker believes it has achieved this seemingly unreachable goal.
