Zhengmy Tire Patch Kit 40 Pieces — 2 Rectangular Sizes (65x80mm & 80x120mm), Thick Rubber for Bike Motorcycle ATV Repairs

Zhengmy 40 Pieces Tire Patches are a portable rubber patch kit in two rectangle sizes designed to seal punctures and restore radial tires on bikes, ATVs, trailers and light vehicles.

This compact kit supplies 40 rubber patches—20 of each size—crafted to offer a quick field or workshop repair option when a puncture or tear threatens a tire’s air-holding ability. The patches are made from thickened rubber to conform to curved surfaces and provide strong adhesion when used with standard vulcanizing cement or rubber glue. Lightweight and easy to store, the set aims to reduce waste and get you back on the road without needing an immediate tire replacement.

How do these patches stop a tire leak?

The rubber patches create a sealing layer over the damaged area that bonds to the tire’s tread or inner surface when used with appropriate adhesive and pressure. Proper surface prep and application help the patch adhere uniformly and resist air seepage under normal driving conditions.

• Use sandpaper or a rasp to roughen the repair area for better bonding.
• Apply a thin layer of rubber glue/vulcanizing cement before placing the patch.
• Press firmly and roll the patch to expel trapped air and ensure contact.
• Allow recommended curing time for maximum seal strength.

Which tires and punctures are suitable for these patches?

These rectangular patches are intended for radial and bias tires on bikes, motorcycles, ATVs, trailers, light trucks and other off-road vehicles. They work best on punctures, small tears and cuts in the tread or inner liner rather than large sidewall blowouts or severely separated tire cords.

• Suitable for tread-area punctures and small cuts.
• Compatible with bicycle, motorcycle, ATV/UTV and trailer tires.
• Not recommended for major sidewall damage or complete cord failure.
• Use with a proper patching procedure for longer-lasting results.

What sizes are included and when should I use each one?

The kit contains two rectangle sizes to match different damage areas: 2.56 x 3.15 inches (65 x 80 mm) and 3.15 x 4.7 inches (80 x 120 mm). Smaller patches are useful for punctures and small nicks; larger patches cover wider tears or multiple adjacent small holes.

• 20 patches at 65 x 80 mm for small punctures and precise coverage.
• 20 patches at 80 x 120 mm for medium tears or larger seal areas.
• Choose a patch that extends beyond the damaged area by at least 10–15 mm.
• Keep both sizes on hand to match the repair to the damage size.

How do I get the best result when applying a patch?

Successful repairs depend on cleaning, roughening, and correctly bonding the patch to the tire surface, plus allowing adequate curing time. Use recommended tools—scraper, rasp, glue—and press firmly to remove air and ensure a continuous seal.

• Clean the area of dirt, oil, and loose rubber before starting.
• Roughen the surface for mechanical grip, then apply adhesive evenly.
• Place the patch centrally and roll to remove bubbles and ensure adhesion.
• Cure the repair as the adhesive manufacturer specifies before inflation.

Who is this for: This Zhengmy patch set is aimed at mechanics, DIY riders and fleet operators who need an economical, portable way to repair common punctures across bikes, ATVs, trailers and light vehicles. It’s a practical addition to roadside kits, workshop benches and farm or off-road toolboxes for anyone who prefers repairing a damaged tire to immediate replacement.
