SUNSOUL Radial Tire Repair Patches 10-Pack 4.73x2.75 in — Heavy-Duty Vulcanizing, Fabric-Reinforced

SUNSOUL 10-pack radial tire patches are heavy-duty inner-tire repair patches (4.73" x 2.75") designed to be vulcanized with chemical cement to restore radial tire air retention and structural support.

These large, reinforced patches are built for radial tire repairs where a durable, airtight bond and restored ply strength are required. Each patch combines a black, flexible rubber compound with a gray gum ply and an embedded fabric reinforcement to resist dimpling and stabilize pressure. They are intended for professional or well-equipped DIY repair and must be applied using a compatible vulcanizing cement for a permanent seal.

How do these patches create an airtight repair?

The patches use a thickened rubber compound plus a fast-adhesive gum layer that chemically bonds to the buffed inner tire surface when used with vulcanizing cement. Fabric reinforcement restores the tire’s structural integrity while the gum ply vulcanizes to form a tight seal that resists air leakage and deformation.

• Black reinforced rubber for flexibility and pressure stability
• Gray gum ply designed for quick adhesion and vulcanization
• Embedded fabric layer recreates ply strength
• Step-down shape improves radial flex behavior

What is the correct procedure to apply a SUNSOUL radial patch?

Prepare the inner surface by sanding or scuffing the damaged area, clean away debris, then apply an approved vulcanizing cement and allow it to dry. Peel the polyester backing, position the patch over the prepared area, press from center to edge, stitch if possible, and finally remove the protective film.

• Sanding/scuffing to remove contaminants and reveal fresh rubber
• Use chemical vulcanizing cement — required for bonding
• Center-to-edge press and optional stitching ensures full contact
• Remove backing film after securing the patch in place

Which punctures and tire locations are these 4.73" x 2.75" patches suitable for?

The medium-large size fits many sidewall-adjacent repairs, inner crown punctures, and cuts up to the patch dimensions; choose the patch size that covers the worst part of the damaged area with overlap. They are optimized for radial tires and intended to handle larger holes than small mushroom plugs or plugs alone.

• Best for medium to large inner-crown punctures and cuts
• Suitable for radial passenger and light-truck tires
• Not intended as a replacement for severely mutilated carcasses
• Requires evaluation of tire safety before repair

What tools and materials do I need to complete a reliable repair?

You will need a tire buffer or sandpaper, a brush and compatible vulcanizing cement, the patch, and a roller or stitching tool to press edges firmly. A balanced workspace, proper ventilation, and safety gear are recommended when handling solvents and working on tires.

• Tire sanding tool or coarse sandpaper for buffing
• Chemical vulcanizing cement compatible with vulcanizing patches
• Rolling or stitching tool to ensure full contact
• Protective gloves and eye protection for safety

Who is this for: These SUNSOUL radial tire patches are made for tire shops, mobile tire technicians, fleet maintenance teams, and skilled DIYers who perform interior radial tire repairs and have access to vulcanizing cement and proper application tools. They offer a cost-effective option to restore air retention and ply strength when a puncture is repairable and the tire has been inspected for overall safety. Always follow industry repair guidelines and local regulations when deciding to repair versus replace a tire.
