Hankook developed the RA 18 as a Highway All-Season tire for light trucks. The Hankook RA 18 tires are designed for drivers who want to experience pleasurable, on-road features, all-season flexibility and long wear including grip in mild snow. All-Season Highway tires patented with the M+S symbol are usually used as O.E. (Original Equipment) on trucks, 2WD and 4WD, pick-ups, light-and-medium duty vans as well as sport utility and crossover vehicles.
Original Equipment (O.E.) All-Season Highway light truck tires are normally purchased to replace worn-out sets/pairs of the original tire a vehicle comes with. Original Equipment tires can be used in axle pairs or sets of four if available in the correct size, speed rating and load range to match the specifications and performance category of current O.E tires.
