SUNSOUL Tire Repair Patches 100-Pack 45mm (1-3/4") — Reinforced Composite, Vulcanizing-Ready

SUNSOUL 100-pack 1-3/4" (45mm) tire patches are reinforced composite-rubber plugs designed for vulcanizing-cement repairs on tubes and tires, providing an airtight fix when applied correctly.

These tire patches are made from a two-layer composite rubber: a flexible black outer layer that stabilizes air pressure and a gray adhesive gum ply engineered to vulcanize with standard tire cement. Sold in a 100-piece roll of 45mm diameter circles, they’re sized to cover common punctures in passenger car, motorcycle, ATV, and light-truck inner linings. These patches require a chemical vulcanizing cement to form a permanent bond; without the cement they will not adhere reliably to the tire inner surface.

How do SUNSOUL patches create a lasting seal?

When used with a compatible vulcanizing fluid, the gray gum ply chemically bonds to buffed rubber, producing an air-tight, flexible repair that resists dimpling and pressure loss. The black outer compound adds structural flexibility so the patched area moves with the tire rather than separating under stress.

• Composite dual-layer design: gray adhesive ply plus reinforced black rubber.
• Requires chemical vulcanizing cement to vulcanize and seal permanently.
• Resists dimpling and retains flexibility under pressure.
• Suitable for radial and bias tires as well as inner tubes.

What size damage can a 45mm patch repair?

A 1-3/4" (45mm) patch is intended for small-to-moderate punctures and cuts; choose a patch at least three times wider than the defect to ensure proper coverage and bonding. The 100-piece quantity gives you multiple repairs or several for a single larger damaged area.

• Diameter: 45mm (1-3/4")—covers most nail punctures, small gashes, and slow leaks.
• Use a patch at least three times the hole diameter for safety and durability.
• Bulk pack of 100 pieces supports multiple repairs or professional use.
• Compatible with bicycle, motorcycle, car, ATV, and light-truck inner surfaces.

How do I apply a SUNSOUL tire patch correctly?

Successful repair depends on preparation and correct vulcanizing technique. Clean and sand the inner wall around the puncture, apply vulcanizing cement and let it dry as directed, then peel the polyester backing and press the patch from center outward before removing the protective film.

• Buff or sand the inner surface to remove contaminants and produce a fresh bonding area.
• Apply a thin layer of chemical vulcanizing cement; allow it to dry fully per product instructions.
• Peel the red polyester backing, center the patch, press from middle to edges, and remove outer film.
• Stitching the patch to the rubber surface with uniform pressure improves adhesion.

Will these patches work with other brands of cement or repair kits?

SUNSOUL patches are formulated to be compatible with most widely available vulcanizing fluids and cement solutions used in tire repair. Always follow the cement manufacturer’s directions and confirm compatibility for best results.

• Compatible with common vulcanizing cements on the market.
• Not intended for cold or pressure-sensitive adhesives—use chemical vulcanizers only.
• Test a single patch if using an unfamiliar cement to confirm reliable vulcanization.
• Intended for inner-liner repairs; consult a professional for sidewall or structural tire damage.

Who is this for? SUNSOUL 100Pcs 45mm tire patches are suited to DIY mechanics, roadside repair kits, small garages, and fleet operators who need a bulk supply of reliable inner-liner repair patches. If you maintain bikes, motorcycles, ATVs, or light vehicles and have access to vulcanizing cement, these patches provide an economical, flexible solution for permanent puncture repairs. For sidewall damage or large structural breaks, consult tire professionals or consider replacement rather than patching.
