For club racers and weekend drivers the Tamiya 53582 Medium-Narrow Medium Foam Inserts provide a reliable way to keep tyre profile consistent on 1/10 scale cars. They sit inside medium-narrow tyres to hold the intended shape as speed increases.
These inserts help the tyre maintain even contact across the tread, which improves grip predictability and reduces unwanted deformation under load. That makes handling more consistent across laps.
Compatible with many 1/10 scale cars, the inserts are useful when you switch tyre compounds or run varied track conditions. They offer extra sidewall support that helps when precise steering feedback is important.
