The G278 MSD Super Single Tire replaces Goodyear’s popular G178 Super Single and provides enhanced mileage, thanks to a 1" larger footprint, deeper tread depth and special compounding. Available in 385, 425, and 445/65R sizes in 22.5, the G278 MSD is a versatile, all position performer in on/off highway applications. The rugged criss-cross tread design helps provide exceptional off-road traction, while it helps to pump away water from the tread for enhanced grip. The tread design also offers a quiet ride, while the tire’s grooved angles with full-width interlocking groove protectors help keep stones from imbedding and drilling into the tread.
