HPI Bullet 3.0 MT and ST Rear Rubber Tires with Alloy 5-Star Beadlocks BMT0503R+889 by GPM  [BMT0503R+889]

Rear beadlock wheel conversion

This aftermarket wheel kit replaces the stock rear wheels on HPI Bullet 3.0 MT and ST nitro models with rubber tyres, nylon rim frames, alloy 5-star beadlock rings and 12x9mm drive adapters supplied in a single set. It is aimed at hobbyists who want beadlock serviceability and a change in rim material without cutting or reworking the axle.

Fitting is familiar to anyone who has serviced nitro rear wheels: split the beadlock halves, mount tyre to nylon frame, line up the alloy star ring and fasten the screws. The included 12x9mm adapters are manufactured to match the stock rear axle stub on HPI Bullet 3.0 MT and ST, providing a secure drive interface.

On track this kit lets you tune rim stiffness and unsprung mass separate from tyre choice, giving more control during setup while keeping original axle and hub geometry intact.

This GPM wheel and tyre assembly is a direct aftermarket replacement for HPI Bullet 3.0 MT/ST nitro models, suitable for racers and weekend trail riders wanting a serviceable beadlock rim and matching drive adapters without changing axle geometry.
