Tires Patching for big size punctures

Tires Patching is a temporary solution to fix punctures or leaks in the tire’s tread area. It must be noted that tire patching should be done on the tire tread and not on the sidewall or shoulder, as those areas are more prone to failure.

When my car tires got penetration of metal cutter piece

Last week, I experienced the tire damage of my new car. As soon as I went to the parking area in the evening to get back home, I found my tires completely flat. I took out the tire inflator and connected it with a socket available in the dashboard lower side. 

The tire inflator started working and filling in air. As soon as it reached 20 psi, and I thought a tire was convenient to drive on, I decided to take the car to a nearby tire shop as some sound of air leakage was coming. I turned off the inflator at 25 psi and immediately drove to a nearby tire shop in 5 minutes. 

The tire shop mechanic informed me that the tire got a big cut puncture and needs checking for repairs. 

As soon as he disassembled the tire and put in air and submerged it in a water pot, there were many bubbles up in the water showing something worse happened. He found a 2.5 inch wider cutting blade piece trapped inside the tire. He disassembled the rim from the tire using a tire machine. There was a big 3 inch length strip found penetrated in the tire. 

He advised me that the tire needed double patching inorder to give enough strength to sustain longer and sealed the area. 

Here’s a step-by-step guide on how he double patch a tire:

Inspecting for Punctures

Inspect the tire thoroughly to locate the puncture. Look for any foreign objects embedded in the tread, such as nails, screws, or sharp debris.

Dismantle the Tires

You may need to remove the tire from the vehicle to properly patch it. Use the jack to lift the vehicle off the ground, and then use the lug wrench to loosen and remove the lug nuts. Take the tire off the vehicle carefully.

Prepare the puncture area

Use the tire reamer or rasp tool from the patch kit to clean and roughen the puncture hole. This helps the patch adhere better. Insert the tool into the hole and twist it a few times to enlarge the opening slightly.

Apply the adhesive

Apply some tire repair cement or rubber cement from the patch kit to the puncture area. This adhesive helps the patch adhere to the tire surface.

Insert the Patch from inside of tire

Take the tire plug or patch from the kit and insert it into the puncture hole using the insertion tool provided. Push it in firmly, making sure it covers the entire hole.

For Double Patching, add rubber tube cut piece with Patch

In case the tire mechanic found big puncture hole due to cut then double patching is required that can be done by taking a piece of rubber tube in equal size of patch from patch kit.

Heating using iron press

For best results use the heating iron press over the tire patching area for about 5 minutes to soften and sticking the rubber patches and piece together on the puncture area.

Sub Assemble the tire with Rim

As soon you found patches completely glued after removing the heating iron, you can assembled back the tire with its rim.

Reinflate the Tire

Before remounting the tire on the vehicle, ensure it is properly inflated. Use a tire pressure gauge to check the tire pressure and inflate it to the recommended PSI, which can be found in the vehicle’s owner’s manual or on a placard on the driver’s side door jamb.

Recheck Leaks

Rechecking the patched tire for any leakages using the same method of dipping tire into water pot before mounting the tire on vehicle.

Remount the Tire

Remount the tire back onto the vehicle’s wheel hub. Tighten the lug nuts in a crisscross pattern to ensure even pressure.

Precaution

Although the tire inflated properly after such repairs but it had a weak area now that can troubled you again any time. Replace your tires within one month in order to keep yourself safe and any future problem due to tire.

TYPES OF TIRE REPAIRS

There are several types of tire repair methods used to fix punctures, leaks, and damages in tires. Each method is suitable for specific types of tire damage. Here are some common types of tire repair:

Patch and Plug (Combination Repair)

This method combines a tire patch and a plug. It involves removing the foreign object causing the puncture, reaming the hole to clean and roughen the area, and then inserting a rubber plug into the puncture to seal it from the inside. Afterward, a patch is applied to the inner liner of the tire to provide an additional barrier against air leakage.

Tires Patch

A tire patch is a small, sticky, and flexible piece of rubber with adhesive backing. It is applied to the inner liner of the tire over the puncture area to seal it and prevent air leakage.

Tire Plug

A tire plug is a small, sturdy rubber plug that is inserted directly into the puncture from the outside of the tire. The plug expands inside the puncture, effectively sealing it and preventing air from escaping.

Tires Patching/Plug Kit

These kits typically contain all the necessary tools and materials, including tires patching, plugs, cement, reamer, and insertion tools. They are widely available at auto supply stores and are suitable for DIY tire repairs on small punctures.

Tire Sealant

Tire sealants come in liquid or aerosol form and are used to seal small punctures in tubeless tires. When the tire rotates, the sealant is forced into the puncture, sealing it from the inside. While they provide a quick and temporary fix, they are not suitable for all tire damages, and they can sometimes cause balancing issues.

Tire Boot

A tire boot is a thick, reinforced rubber patch that is applied to the inside of the tire to cover and reinforce larger punctures or cuts. It is commonly used for sidewall punctures or damage.

Tire Inner Tube Replacement

In the case of inner tubes used in some tires (e.g., bicycle or some small vehicle tires), repairing a punctured tube involves patching it or replacing the entire inner tube.
