Frequently Asked Questions
- What size rock crawler tyres are these inserts designed for? — These SWEEP soft double-stage inserts are specifically engineered for 1.9-inch rock crawler tyres, the industry standard size for scale rock crawling and obstacle course applications. The 116mm outer diameter and 39mm width dimensions are designed to match typical 1.9-inch crawler tyre specifications.
- What is the difference between single-stage and double-stage inserts for RC crawlers? — Double-stage inserts, like this SWEEP product, feature a two-layer design that provides superior compliance and load distribution compared to single-stage alternatives. This advanced construction allows the tyre to grip obstacles more effectively whilst maintaining structural integrity, resulting in better traction and more predictable handling on challenging terrain.
- Are these inserts suitable for beginners new to rock crawling? — Yes, these SWEEP inserts are an excellent choice for anyone developing their rock crawling skills. The soft compound provides forgiving performance that helps newer drivers build confidence whilst learning proper crawling techniques. However, they're equally at home in competitive environments, making them a versatile choice for the entire spectrum of RC crawlers.
- Will these inserts work with any 1.9-inch crawler tyre? — These inserts are designed for standard 1.9-inch rock crawler tyre applications. For best results, verify that your specific tyres are compatible with aftermarket inserts, as some premium or speciality tyres may have proprietary insert systems. The supplied dimensions of 116mm outer diameter and 39mm width cover the vast majority of 1.9-inch crawler tyres available in the UK market.
- How often should I replace rock crawler tyre inserts? — The lifespan of tyre inserts depends on usage intensity, terrain difficulty, and driving style. Competitive crawlers may replace inserts more frequently than recreational users. Regular inspection will reveal when the soft material has worn sufficiently to warrant replacement, typically indicated by reduced grip and increased tyre sidewall flex.
- What makes FMS SWEEP inserts a trusted choice? — SWEEP is a recognised manufacturer of quality RC crawler components, with proven performance in competitive and recreational rock crawling worldwide. FMS products are distributed through authorised retailers like RC Model Shop, ensuring you receive genuine components backed by proper support and warranty consideration.
