This 40 Series wide-offset wheel and tyre pair is supplied as a single purple pair intended for hobbyists and tuners working on Traxxas Revo and HPI Savage platforms. The set lets builders trial changes to track width and scrub geometry without claiming specific performance gains.
Installation uses the vehicle's existing wheel hex and mounting hardware where compatible. Technicians should confirm hub hex dimensions and wheel nut thread to determine if adapters or different fasteners are required for precise fitment.
From a setup perspective, wider offsets alter lateral load paths and scrub radius; evaluate steering behaviour, bearing loads, and tyre wear during controlled test sessions and adjust suspension geometry incrementally to optimise handling.
For precise tuning work, treat this pair as an experimental fitment to assess changes in handling and component loads; verify fit and monitor bearing and suspension wear during initial runs.
