If you race or bash 1/10 scale off-road rigs, the HUDY 834301F foam inserts give the front tyres extra internal support. They are made to fit the front wheels of 4WD models and help keep the tyre profile stable over rough ground.
The HUDY 834301F reduces sidewall squirm and keeps the tread flatter against the surface, improving grip predictability. That steadier contact patch helps when pushing through corners or over ruts.
These inserts are especially handy on abrasive or uneven dirt where tyre deformation can upset handling. They are a simple, low-cost tune for drivers wanting cleaner steering and repeatable handling.
