Plews 150/70-18 The Big Boy ADV

True adventure demands true off-road capability. The Big Boy tire is the result of more than 24 months of research and development. Our goal was to bring our experience from enduro racing—where we’ve won world championships—to the world of true off-road adventure—and this is the result.

This is not a tire for Sunday rides with friends. The Big Boy is designed for riders who demand real off-road performance from their adventure bike. Mud, rocks, hills, logs, ruts, technical climbs—wherever you want to go, The Big Boy is built to get you there.

Thanks to a unique tread pattern inspired by traditional enduro tires, The Big Boy offers excellent traction, self-cleaning capabilities, and handling—while being reinforced to handle the higher weight, torque, and speed of modern adventure motorcycles. It’s built to handle even the toughest conditions and maintain grip, even when conditions get brutal.

A specialized approach to tread design focused on reducing chipping and chunking for consistent performance and durability.

A compound development philosophy that strengthens the rubber to minimize tearing and block damage—extending both lifespan and grip.

Our proprietary carcass stabilization system that controls sidewall flex under load, ensuring constant forward drive without excessive roll or loss of traction.
