The Alpha Rider tool streamlines wheel mock-ups by attaching to the hub and giving clear, front-facing readings for diameter, width, and offset so you can verify clearance against fenders and suspension before mounting tires. Built from 6061 aluminum with stainless hand screws, this updated model measures inner and outer lips and accepts most common bolt patterns.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I use the Alpha Rider tool to check wheel offset and clearance?\u003c\/h3\u003e\n\u003cp\u003eMount the tool base to the hub, enter wheel height and width, then align the indicator to the wheel lip. Read the offset from the front-facing scale and compare the red reference line to your fender or mock-up surface to confirm fitment.
