Engineered radial tyre for Savage 21 applications

This radial rubber tyre is moulded to fit HPI Savage 21 wheel standards and incorporates a purpose-shaped foam insert to control deformation under load. The construction targets consistent contact behaviour and repeatable feedback for suspension tuning and traction testing.

Standard Savage 21 tyre mounting procedures apply; use conventional tyre adhesive where required. The tyre is intended as an aftermarket tuning component to alter grip characteristics and suspension interaction during setup work.

A precision-fit radial tyre option for hobbyists and tuners who want to evaluate traction and suspension response on Savage 21 platforms.

Is this tyre a drop-in replacement for Savage 21 wheels?

Yes. It matches Savage 21 wheel sizing and mounts using standard techniques for that platform.

What performance change should I expect?

Expect a steadier contact patch and clearer suspension feedback, which can translate to more consistent lap times and easier tuning of corner entry and mid-corner balance.

Do I need special tools to fit the tyre?

No special tools are required beyond typical tyre-mounting equipment; standard tyre glue and common workshop tools are sufficient.

How should I approach setup after fitting these tyres?

Make incremental suspension and tyre pressure adjustments (where applicable) and log handling changes to determine the optimal combination for your track conditions.
