For example, you can receive 3 tires in one day and the 4th one the next day or the day after, or one tire in one day and the second one day after. We understand that this is a big inconvenience for our buyers, however, this is ABSOLUTELY out of our control.

Cooper Work Series RHT


  • Improved load capacity
  • All season performance
  • Longer lasting tread life


The Cooper Work Series RHT is a highway terrain, all season tire manufactured for commercial vehicles. This model is made for the vehicle’s trailer axle.

This model utilizes its reinforced internal construction that supports the model while under load and driving pressure. These strong structural materials prevent the tire from losing its optimal shape throughout the performance, allowing it to carry and withstand larger loads with ease. The robust tread design balances out pressure to avoid pressure accumulation in one spot, keeping the model in its shape. As the tire does not deform, it is able to perform remarkably well in heavy-duty conditions, making it a superb choice for long-haul applications.

The strong compound materials work together with the specially designed tread to improve the tread and service life. These materials avoid external damage such as tread chipping, cracking, and tearing, while also slowing down the treadwear rate. The ideal tread design ejects rocks from the footprint and prevents them from digging into the tread area and harming the casing. The tire resists irregular and premature wear as it evenly distributes load and driving pressure across the tread area. In this manner, the tire promotes a longer tread life and phenomenal usability.

The Cooper Work Series RHT is able to perform exceptionally well in all weather conditions, utilizing its ribbed tread design and durable compound materials. The five-rib tread design maintains a consistent contact with the driving surface and enhances the traction on dry, wet, and snowy roads. The compound keeps the rubber flexible in both high and low temperature conditions, while the circumferential groove design eliminates water and slush from the footprint. The combination of these features offer a safer year round driving experience.
