The Traxxas 5871R ultra‑soft S1 compound off‑road racing tires are designed for maximum traction and grip on loose dirt, gravel, and rough terrain, featuring a dual‑profile SCT 4.3 × 1.7–2.2/3.0 inch size that provides excellent acceleration, braking, and cornering performance, and they come pre‑mounted with foam inserts for consistent support and handling, making them ideal for competitive racing and aggressive trail driving. These tires are compatible with short‑course trucks and other 1/10‑scale SCT vehicles that accept 4.3 inch off‑road tires, including Traxxas models such as Slash and other similar SCT platforms that use this tire size and profile.
