HPI Bullet 3.0 MT and ST Rubber Rear Tires with Nylon Frames Alloy 5-Star Beadlock Rims and 12x9mm Drive Adapters by GPM BMT0503R+889  [BMT0503R+889]

Rear tire and beadlock upgrade

This GPM aftermarket kit replaces the stock rear wheels on HPI Bullet 3.0 MT and ST nitro models with a combination of rubber tires, nylon rim frames, alloy 5-star beadlock rims and 12x9mm drive adapters. The set addresses wheel mounting and drive interface in a single package so builders can restore wheel fitment or change rim materials without modifying the vehicle’s drivetrain.

Installation is straightforward for anyone familiar with rear wheel removal on nitro buggies and trucks: separate the beadlock halves, mount the rubber tire onto the nylon rim frame, align the alloy 5-star ring and fasten the hardware. The included 12x9mm drive adapters match the standard rear axle stub used on HPI Bullet 3.0 MT and ST nitro variants to ensure axle engagement without machining or trimming.

From a tuning perspective this kit lets you modify unsprung mass distribution and rim stiffness independently of tyre compound selection. Use this set when you need a direct-fit replacement that keeps the original axle and hub geometry intact while changing rim material or adding beadlock styling and serviceability.

This GPM wheel and tyre assembly is a direct aftermarket replacement for HPI Bullet 3.0 MT/ST nitro models, suitable for hobbyists who want a serviceable beadlock rim and a matched drive adapter without altering axle geometry.
