The ZeroRC Hub-T2-3 is a 20mm narrow drift tire designed for the RW00 series. While the more common T2-1 and T2-2 tires use a standard 22mm diameter, the T2-3 is specifically sized for 20mm wheel hubs. 
 
Key Specifications:
 
Dimensions: 20mm diameter (Narrow).
Material: High-precision CNC-machined Saigang (POM), known for providing a stable and consistent slide on smooth surfaces like P-tile and carpet.
Visual Detail: Features a printed ZeroRC logo on the sidewall for scale authenticity.
Packaging: Typically sold as a 4-pack (enough for one full car). 
 
Comparison to Other T2 Series Tires:
 
Unlike the 22mm variants, the 20mm T2-3 tires are often used to fit smaller scale body shells or for specific tuning needs that require a smaller overall wheel height:
