SUNSOUL radial tire patches 10-pack 2.76×4.72 in — large heavy-duty, fast-vulcanizing

SUNSOUL 10-pack large radial tire patches are heavy-duty, pre-vulcanized repair patches sized 2.76"×4.72" (70×120 mm) designed to deliver faster vulcanization and a stronger, heat- and pressure-resistant bond when used with vulcanizing cement.

These patches use SUNSOUL's updated 2026 compound to speed the repair process and improve the sealed joint's strength. Each pack contains ten oversized patches suitable for a wide range of punctures — from nails and screws to gravel cuts — and is engineered to meet the higher load demands of modern vehicles, including electric cars. They are intended as an interior tire repair applied to the inside of the tire carcass and must be combined with proper vulcanizing cement for a lasting, safe seal.

How do these patches speed up the repair and improve durability?

The 2026 formula increases the proportion of pre-vulcanized rubber so the molecular bonding achieves full strength faster under heat and pressure. That means shorter cure times and a tighter, more uniform seam compared with older patch materials. The result is a repair that resists delamination and secondary leaks when installed correctly.

• 40% more pre-vulcanized rubber for quicker vulcanization
• Improved molecular seal to reduce leak risk
• Designed for heat- and pressure-resistance after cure

Can these patches handle heavy loads and modern vehicles like EVs?

Yes — SUNSOUL tested this design to carry roughly 30% more load capacity than conventional patches, making them suitable for heavier axles and frequent highway use. While over-engineered for most gasoline vehicles, their extra strength addresses the higher torque and weight profiles of many electric vehicles. Proper application and use of vulcanizing cement are essential to achieve the rated performance.

• 30% higher tested load capacity versus standard patches
• Appropriate for cars, trucks, SUVs, and many EVs
• Large 70×120 mm area suitable for larger punctures and overlapped repairs

What must I use with the patch for a safe, long-lasting repair?

These patches require a compatible vulcanizing cement to chemically bond the patch to the tire’s inner liner. The cement softens both the patch and tire surfaces, enabling a heat-activated vulcanization that creates a permanent, heat- and pressure-resistant union. Without cement, the patch cannot form the intended molecular seal and may detach or leak under driving conditions.

• Use industry-standard vulcanizing cement for best results
• Apply recommended heat/pressure during cure per repair guidelines
• Follow tire repair safety steps and inspect the repair before use

What types of damage and driving scenarios are these patches suited for?

The oversized shape and heavy-duty compound handle punctures from nails, screws, and sharp debris as well as small cuts from gravel or rough roads. They’re intended for interior repairs on tubeless radial tires and work across urban commutes, long-distance highway travel, off-road use, and light commercial freight. For large sidewall tears or structural damage, replacement is still recommended.

• Works for punctures caused by nails, screws, and road debris
• Suitable for commuting, long trips, off-road, and commercial use
• Not a substitute for replacement after major structural tire damage

Who is this for: SUNSOUL's large heavy-duty radial patches are aimed at vehicle owners and tire technicians who want a robust, high-capacity interior repair option. Ideal for private car drivers, fleet managers, truck operators, and anyone who wants fewer repeat repairs — especially owners of heavier vehicles or EVs seeking stronger patch performance. Keep a pack with compatible vulcanizing cement in your workshop or roadside kit for reliable on-the-spot tire repairs.
