HPI Savage 21 Radial Rubber Tire with Foam Insert by GPM SAV1889PW  [SAV1889PW]

Radial Tire for HPI Savage 21

This radial rubber tire with internal foam insert is specified for the HPI Savage 21 scale platform and is intended as a direct-fit option for Savage 21 wheel setups. The design uses a radial rubber casing combined with a foam core to stabilise the tyre profile under load and offer a predictable contact patch for off-road surfaces.

Fitment and installation follow standard tyre-mounting practice for Savage 21 wheels, using the vehicle's existing rims and tyre adhesive where required. No additional parts are necessary beyond common workshop supplies. The tyre's role is focused on tuning: changing to this radial tyre can alter traction characteristics, feedback to suspension, and cornering balance when used alongside suspension and gearing adjustments.

This tyre is a straightforward upgrade choice for Savage 21 owners seeking a radial-profile option to refine on-track grip and suspension interaction; pair it with incremental suspension tuning to evaluate changes in handling.
