Ideal for RC Rock Climbing Car

• Tailored 2.2" Fit: Sized for 132–134 mm 5.25" OD crawler tires; the 125×45 mm profile delivers a snug seat that stabilizes tread blocks and contact area.
• Silicone Advantage: Non‑absorbent, temperature‑stable silicone resists waterlogging and breakdown—keeping performance consistent in rain, mud, or snow.
• Controlled Compliance: soft compound balances flex with support to curb tire squirm, hold sidewalls on off‑camber lines, and maintain tread shape.
• Traction With Stability: Added mass versus foam helps lower effective CG, improving bite on rock faces, side‑hilling security, and slow‑crawl precision.
• Built to Last: Durable, easy‑to‑install inserts pair well with vented tires; includes 4 inserts to outfit front and rear.
