Radar R-A1 is an all-season highway terrain tire made for commercial vehicles. It features an all-weather symmetric tread pattern and features the optimal siping detail that helps to maintain a firm and consistent grip in any weather conditions. The tire’s compound is flexible enough to run even in colder temperatures and the sipes can optimally grip the road surface. Radar R-A1’s four circumferential grooves help to effectively evacuate water and slush away from the tire’s footprint, which also helps to resist hydroplaning. Radar designed this tire with closed shoulder ribs that help to keep the tire’s contact at all times, improving the tread life by applying an even pressure while driving. It also helps to enhance Radar R-A1’s braking and cornering abilities by equally spreading out the pressure on the tire’s surface, which prevents it from having irregular wear along the tread area.
