HPI Bullet 3.0 MT and ST Front beadlock wheel upgrade BMT0503F+889 by GPM  [BMT0503F+889]

Front beadlock wheel set

This front wheel and tyre set is built for HPI Bullet 3.0 MT and ST nitro chassis. It pairs rubber front tyres with lightweight nylon rim frames and alloy 5-star beadlock rings, and includes 12x9mm drive adapters to mate with the specified HPI hubs. Supplied as a one-pair front set, it is intended for quick replacement or modest handling upgrades.

Assembly uses standard beadlock technique: separate the ring, position the tyre on the rim frame, align and tighten the ring fasteners. The 12x9mm adapters match the Bullet 3.0 stub axle interface, so check spline orientation prior to final tightening. Typical workshop checks are bead seating, static balance and ensuring no visible wobble once fitted.

From a setup perspective the kit influences turn-in and bite. The rubber compound offers consistent traction on off-road tracks and mixed surfaces, while the alloy ring increases wheel stiffness. The nylon rim frame reduces peripheral mass versus full-metal wheels, which can alter steering feel and may benefit from small suspension or toe tweaks to recover the desired handling balance.

Install this pair as a direct front swap or as part of a front-end setup change for HPI Bullet 3.0 MT/ST nitro cars; confirm adapter orientation and balance wheels after installation for consistent steering performance.
