Serious about RC crawling? This HOBBYSOUL 4-pack of wheels and tires is a major upgrade. You get four complete, pre-mounted units: each one has a 2.2 inch aluminum beadlock wheel paired with a super grippy, sticky compound tire (5.0 inches tall, 2.12 inches wide). The tires come with foam inserts inside. The magic is in the wheels – they have an adjustable offset system. You can set them to four different negative offsets: -4mm, -7mm, -14mm, or -17mm. This lets you fine-tune the width and stance of your rig for better stability on rocks, mud, or trails. Changing the offset is done by rearranging the center part and a red gasket – check the pictures for the setup. The tires are made from a special soft compound that stays sticky in various conditions (hot or cold) and offers amazing traction on rocks, dirt, and mud. They fit a standard 12mm hex. This set is perfect for popular crawlers like the Axial Capra, Axial Wraith, Traxxas TRX4, Traxxas AMG 6x6, Redcat Gen8, Redcat Everest Gen7 Pro, and many others. If you want more grip and a customizable look, this is a top-notch choice.
