The Goodyear OMNITRAC S HEAVY DUTY (HD) tyre is a mixed service steer-axle tyre for on-road and more challenging off-road applications. The Goodyear OMNITRAC S HEAVY DUTY features DuraShield technology which mean Goodyear guarantee retread casing acceptance and offer tyre damage cover. The Heavy Duty (HD) version of the tyre is designed for mainly off-road jobs, as they offer better grip and durability than the regular OMNITRAC S tyres, which is essential if you're driving on muddy terrain. The alternative non HD version is better suited for those who do most of their driving on the road.
