This radial rubber tyre features an internal foam insert and is sized for HPI Savage 21 wheel assemblies as a direct-fit option. The foam core supports the tyre shape under cornering loads to deliver a more repeatable contact patch on off-road layouts.
Fitting uses normal Savage 21 tyre mounting routines and the vehicle's existing rims; apply tyre adhesive if needed. Fitting these tyres is a tuning step that alters traction balance and suspension feedback when compared with original tyres.
A straightforward upgrade for Savage 21 users aiming to tweak grip and handling; adjust setup progressively to assess changes.
