CKAuto Bias Tire Repair Patches 10-Pack — 135mm (5-5/16") Heavy-Duty Reinforced for Off-Road & Industrial Tires

CKAuto 10-pack heavy-duty bias tire patches are large, durable repair plugs designed to restore bias-ply agricultural and construction tires quickly and permanently. CKAuto bias tire patches come as ten 135mm (5-5/16") circular repair patches formulated for demanding off-road and industrial use. Engineered to bond with bias-ply tire carcasses, these patches support both cold vulcanizing with cement and hot vulcanizing for sidewalls, giving maintenance crews a versatile solution for common tire damage. The reinforced construction and thick rubber base reduce edge lift and resist the multi-directional stresses typical of heavy equipment, so repairs hold up under continuous flex and heavy loads.

How do these patches hold up under heavy-duty use?

These patches are built for strenuous environments—agriculture, construction, and mining—where tires experience deep cuts, repeated flexing, and high loads. The layered, reinforced design distributes stress and maintains adhesion even under continuous movement.

• Reinforced grid backing prevents bubbling and improves bonding
• Thick rubber base stabilizes pressure across the repair area
• Formulation resists shear forces from multi-directional loads
• Large 135mm diameter covers major damage zones

Can I install these patches myself and which methods are supported?

Yes—these patches are suitable for professional technicians and experienced maintenance staff using standard repair steps. They support cold vulcanizing (cement method) for general repairs and hot vulcanizing specifically for sidewall work; follow safety guidelines for each method.

• Simple five-step installation: clean, apply cement, wait, position patch, press
• Cold vulcanizing recommended for most repairs with the supplied cement
• Hot vulcanizing usable for sidewalls—do not apply heat to radial treads
• Reinforced surface helps eliminate air pockets for airtight seals

What size and coverage do these 135mm patches provide?

Each patch measures 135mm (5-5/16") in diameter, giving broad coverage to repair sizable punctures and worn areas without needing multiple pieces. Ten patches per kit make this a cost-effective option for fleet maintenance programs.

• 135mm diameter covers larger damage than standard small plugs
• Ten patches included for multiple repairs or spare inventory
• Designed to conform to bias-ply contours to minimize edge lifting
• Gray gum layer ensures airtight chemical vulcanization bond

Are there any important safety tips or limitations?

Follow the manufacturer’s instructions and general tire-repair safety practices. Do not heat the tread area of radial tires—only use hot vulcanizing on sidewalls where specified—to avoid damage to embedded components like steel belts.

• Never apply heat to radial tire treads to prevent internal damage
• Use hot vulcanizing only for sidewall repairs when appropriate
• Ensure the repair area is fully cleaned and prepped for best adhesion
• Inspect repaired tires before returning to service under load

Who is this for These CKAuto heavy-duty bias tire patches are aimed at fleet managers, agricultural operators, heavy-equipment mechanics, and field service technicians who need a durable, reliable repair option for bias-ply tires. If you maintain tractors, harvesters, loaders, bulldozers, or off-road trucks and require large, permanent patches that resist flexing and harsh conditions, this 10-pack offers practical coverage and flexibility for in-field and workshop repairs.

FAQ

Q: Can these patches be used on radial tires?

A: They are formulated for bias-ply tires; hot vulcanizing is only safe on sidewalls. Do not heat radial treads.

Q: How many repairs will one kit cover?

A: The kit contains ten 135mm patches — coverage depends on damage size, but it’s designed for multiple large repairs.
