CKAuto Tire Patch Kit 100 pcs All-Purpose Assortment — Heavy-Duty Self-Vulcanizing Patches (5 Sizes)

CKAuto 100-piece all-purpose tire patch kit supplies heavy-duty self-vulcanizing patches in five sizes to repair radial and bias-ply tires quickly when used with chemical vulcanizing cement.

This repair assortment gives you a range of patch shapes and sizes for common punctures in car, truck, motorcycle and inner tires. The kit contains thick black rubber bases with a gray gum sealing layer that chemically bonds to the tire when activated by vulcanizing cement (cement not included). Reinforced backing helps prevent dimples and air pockets, making the patches suitable for shop use, fleet maintenance, and at-home DIY fixes.

How do I use these CKAuto patches correctly?

Use a clean, dry area of the tire and follow a five-step process: clean, apply chemical vulcanizing cement, let tack, position the patch, and press firmly. The patches require a separate vulcanizing cement to form a permanent bond; without it the patch will not adhere properly.

• Clean tire surface and roughen with buffer or sandpaper.
• Apply compatible vulcanizing cement and allow it to become tacky.
• Position patch, press from center outward to avoid bubbles.
• Use rolling or clamping for full contact and cure time per cement instructions.

Which tire types and punctures are these patches good for?

These patches are engineered for both radial and bias-ply tires plus inner tubes commonly found on cars, trucks, motorcycles, and lawn equipment. They are intended for small to moderate punctures where a vulcanized patch can restore an airtight seal.

• Compatible with most passenger and light-truck tires.
• Works on inner tire areas and many inner tubes.
• Best for punctures, not for large sidewall damage or structural failures.

How durable and reliable are CKAuto tire patches long term?

The patches use a thick rubber base for flexibility and an engineered gum layer that chemically vulcanizes to the tire for an airtight, dimple-resistant seal. When applied with proper vulcanizing cement and installation technique, they provide a long-lasting repair that stabilizes internal pressure and resists separation under normal driving conditions.

• Thick black rubber backing for flexibility and pressure stability.
• Gray gum sealing layer designed for chemical vulcanization.
• Reinforced backing grid to minimize air pockets and dimples.
