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

Front beadlock tyre assembly

This front tyre and wheel assembly fits HPI Bullet 3.0 MT and ST nitro machines. The set combines rubber front tyres on nylon rim frames with alloy 5-star beadlock rings and includes 12x9mm drive adapters to match the Bullet 3.0 hub interface. The pack is supplied as a one-pair front set and is suitable for straightforward replacements or light-weight front-end upgrades.

Installation uses conventional beadlock steps: separate the ring, mount the tyre on the rim frame, align the ring and tighten the fasteners. The included 12x9mm adapters are sized for the target stub axles, so confirm spline alignment before final tightening. Common setup tasks include seating the bead evenly, tyre balancing, and a final check for wobble at operating speed.

In practice this kit alters initial turn-in and front traction. The rubber compound is tuned for predictable grip on off-road and mixed surfaces, while alloy beadlocks add rigidity to the wheel. The lighter nylon rim frame reduces unsprung mass at the outer diameter compared with full-metal wheels, which can affect steering feel and may require minor suspension tuning to regain ideal handling.

Fit this set as a direct front replacement or as part of a front-end tune for HPI Bullet 3.0 MT/ST nitro cars; always check adapter orientation and balance wheels after fitting to maintain steering accuracy.
