HPI Racing Inner Foam 24mm Med/Hard RC Tyre Insert 1/10 Scale - HPI4632

The HPI Racing 4632 inner foam is a 24mm medium/hard tyre insert for 1/10 scale RC tyres. These foams sit inside the tyre to support the carcass and control how it deforms under load, helping maintain consistent grip and tyre shape on track. The medium/hard compound gives a firmer feel than soft inserts, making it a good match for higher-grip surfaces and faster running where you want the tyre to hold its profile. As a set of RC tyre foams, they're a straightforward replacement when your old inserts have packed down or torn, or an option for tuning the handling of your 1/10 radio control tyres.
