CKAuto Tyre Patch Kit 100-Piece All-Purpose Round & Assorted Patches — Heavy-Duty Self-Vulcanizing

CKAuto 100-piece All Purpose tire patch kit supplies a heavy-duty assortment of self-vulcanizing patches for radial and bias-ply tires to repair punctures and restore an airtight seal when used with vulcanizing cement.

This repair kit combines multiple patch shapes and sizes so you can keep a single inventory for cars, trucks, motorcycles and inner tubes. The patches feature a thick black rubber backing for flexibility and a gray gum sealing layer that activates through chemical vulcanization to form a durable, dimple-resistant bond. Note: chemical vulcanizing cement is required to activate the patches and is sold separately.

How do these patches work with different tire types?

CKAuto patches are made to be compatible with both radial and bias-ply constructions as well as inner tubes. The flexible rubber backing conforms to curved tire surfaces while the sealing gum bonds under chemical vulcanization, creating an airtight repair appropriate for light- to medium-duty punctures.

• Designed for radial and bias-ply tires, and inner tubes
• Flexible backing stabilizes air pressure across curved surfaces
• Sealing layer becomes airtight only after applying vulcanizing cement
• Suitable for cars, light trucks, motorcycles, and general workshop use

What sizes and shapes are included, and when should I use each?

The kit contains a mix of round, square and oval patches to address different puncture types and locations. Smaller rounds and squares are ideal for nail-sized holes; larger rounds, squares and ovals cover bigger tears or repairs near the shoulder and tread where more surface area is needed.

• 25 × 45mm rounds for common small punctures
• 15 × 60mm rounds for larger or irregular holes
• 25 × 45mm squares and 15 × 55mm squares for flat contact area repairs
• 20 × 40×65mm ovals for elongated cuts or multi-hole zones

How do I apply a CKAuto tire patch correctly?

Application follows a simple five-step workflow: prepare the surface, apply vulcanizing cement, wait for the cement to become tacky, position the patch, and press firmly. The reinforced backing helps prevent trapped air and dimpling, and proper chemical activation is essential—without compatible cement the patch will not form a permanent bond.

• Clean and roughen the puncture area for best adhesion
• Use a compatible vulcanizing cement (not included) and allow it to flash
• Place patch precisely and press to remove air pockets
• Follow cement manufacturer cure times before re-inflating the tire

What limitations and cautions should I know before using this kit?

These patches are intended for repair of punctures and small tears on many tire types but are not a substitute for professional inspection after major damage. The kit requires chemically vulcanizing cement to activate the gray sealing layer; using regular adhesives will not produce a safe, air-tight vulcanized bond.

• Cement is required and not included—purchase from major brands
• Not intended for large sidewall blowouts or extensively damaged tires
• Professional mounting/balancing recommended after repair when needed
• Follow vehicle and tire manufacturer guidelines for repair limits

Who is this for: The CKAuto 100 pcs All Purpose Round Tire Patches kit is aimed at repair shops, fleet maintenance teams, roadside service providers and DIYers who want a versatile, heavy-duty assortment to handle most puncture repairs. If you keep tires in service—on cars, light trucks, motorcycles or spare inner tubes—and you already use or plan to buy vulcanizing cement, this kit streamlines parts inventory and delivers dimple-resistant, long-lasting repairs when applied correctly.
