The IRC GP-1 rear motorcycle tire is designed for riders who need dependable handling on pavement with added traction for occasional off-road use. This 4.10-18 tire features a versatile 90% on-road and 10% off-road design, making it suitable for dual-purpose motorcycles used for commuting, touring, gravel roads, and light trail riding. The IRC GP-1 combines predictable street performance with tread features that help maintain control on loose surfaces.
Specially shaped knobs penetrate loose terrain to improve traction during acceleration, braking, and cornering off the road. Compared with a full knobby tire, the tread is designed to provide longer wear when used primarily on pavement, helping balance road durability with off-road capability. The tread pattern supports responsive handling and control across changing surfaces without sacrificing everyday street usability.
This rear tire is marked 59P and is intended for compatible motorcycles requiring a 4.10-18 rear fitment. Verify the motorcycle manufacturer’s recommended tire size, load rating, speed rating, wheel configuration, and clearance before installation. The IRC GP-1 is manufactured by IRC and identified by manufacturer part number T10137 and vendor part number T10137.
