Tires with Foam Inside for Noise Reduction & Thermal Insulation

(Ultra-Light 4–6 kg/m³ Aerospace-Grade Melamine Foam)

Product Overview

SINOYQX offers a complete noise-reduction and thermal-insulation solution for tires of all sizes and vehicle types—passenger cars, SUVs, EVs, and commercial fleets.
By bonding a ring of ultra-light 4–6 kg/m³ melamine foam to the inner wall of the tire, this technology dramatically suppresses tire cavity resonance and lowers overall road noise, while providing an extra thermal barrier for improved driving comfort.

Key Advantages

• Proven Noise Reduction
  • Overall cabin noise reduction of 1–3 dB(A)
  • Tire cavity resonance (180–240 Hz) reduced by 5–8 dB
• Ultra-Lightweight
  • Density only 4–6 kg/m³
  • Typical foam weight per tire 10–20 g, negligible effect on wheel balance
• Extreme Temperature Resistance
  • Continuous service range –200 °C to +240 °C
• Thermal Insulation
  • Reduces heat transfer from tire cavity to the cabin and braking system
• Eco-Friendly & Safe
  • Halogen-free, low-VOC, compliant with RoHS, REACH, and global automotive VOC standards

Universal Sizing & Customization

We customize dimensions to any tire width, aspect ratio, and brand requirement—ideal for OEM production lines or aftermarket upgrades.

Installation & Adhesion

1. Surface Preparation – Clean and degrease the inner cavity with alcohol-based or OEM-approved cleaners.
2. Dual-Bonding Method
   • High-temperature acrylic pressure-sensitive tape (≥120 °C): e.g. 3M™ 9080HL, tesa® 51970.
   • Spot hot-melt adhesive (softening point 120–140 °C): provides extra security under high-speed operation.
3. End Gap – Leave a 15–25 mm gap to accommodate thermal expansion and maintain wheel balance.
4. Final Wheel Balancing – Perform a secondary balance check after installation to meet OEM NVH standards.
