Radial tire optimised for HPI Savage 21

This radial rubber tire uses an internal foam insert and a flexible radial casing to suit HPI Savage 21 wheel dimensions as a direct-fit replacement. The foam core helps maintain the tyre profile under load, delivering a consistent contact patch for varied off-road surfaces.

Installation follows standard Savage 21 tyre mounting practice using existing rims and tyre adhesive where required. No special adapters are necessary. Swapping to this radial tyre is primarily a tuning move, changing traction feel and suspension feedback when tested alongside small suspension or gearing adjustments.

  • Compatibility HPI Savage 21

A simple upgrade for Savage 21 owners wanting a radial-profile tyre to fine tune grip and handling; evaluate changes incrementally to find the best setup.

Will this tire fit standard Savage 21 rims?

Yes. It is produced to fit Savage 21 wheel bores and mounts using normal tyre mounting techniques for that platform.

Do I need extra inserts or glue?

The tyre includes an internal foam insert; you should use standard tyre adhesive to bond the tyre to the rim if your setup normally requires glue.

How does the foam affect handling?

The foam supports the casing to reduce collapse under load, producing a more repeatable contact area and clearer feedback for suspension and traction tuning.

Is this tyre for road use?

No. It is specified for RC off-road use on Savage 21 models and is not suitable for real vehicles.
