The Continental HDR or, heavy duty drive axle regional, is an on off road tire, made for commercial use, that developed for single or dual application use on the drive axles of medium-duty vehicles. The main purpose of the HDR is to provide remarkable on and off highway service along with traction in dry, wet and wintry conditions, including snow. What makes Continental HDR stand out from any other type of tire is its remarkable features. It has a deep cut and resistant thread compound that increases the tire’s grip on the road. One of the most remarkable features is the pyramidal ejectors. They are responsible for reduction of stones retained within the tire threads ensuring a longer casing life. The Continental HDR also features a robust shoulder rib that is responsible for long thread life especially on high scrub application. The visual alignment indicators in Continental HDR alert users of any tracking problems. It can also easily accommodate an on and off highway service but this depends on the conditions. When driving on the highway with the Continental HDR, it is important to stick to 65mph. This is the optimum speed when carrying certain loads unless indicated otherwise. To ensure that your tire is not prone to cuts and abrasion the Continental HDR features a scuff rib, which protects the tire. Its aggressive thread design also plays a huge role in ensuring lateral stability, which minimizes twisting and improves performance in wet conditions. The open shoulder thread ensures that there is an even thread wear which reduces noise and improves traction.
