What should I be concerned about when I have a flat tire?
When anobject such as a nail breaks through the inner liner of a tire, your mostimmediate concern as the customer is the loss of air pressure and safety of thetire. The long-term risk is that the instability around the penetrating objectcan lead to tread separation.
What are the primary considerationswhen repairing a punctured tire?
There are three primary considerations when repairing a punctured tire.
1. The amount of damage caused. This can be evaluatedby analyzing the object that punctured the tire.
2. Next, ensure there is an airtight seal of thetire's inner liner.
3. Completely filling the path the object took throughthe tire.
What type of repair fulfills a flat tire’sprimary considerations?
A mushroom-shaped patch and plug combination repairis considered to be the best method of repairing a punctured tire as it fillsthese three requirements. This is the method that Big Brand Tire & Serviceuses.
Whatare the three most common methods to patch tires?
There are different methods that people use topatch their tires. The three most common methods are: the patch and plug combo(mentioned above), the string plug, and the patch method.
The String Plug Method
The string plugmethod is a very popular method used by off-road enthusiasts when they get apuncture in their tire while driving off-road. The reason off-road enthusiastsuse the string plug method is that it does not require the tire to be removedfrom the rim of the car. Essentially, the string plug only fills the hole inthe tire.
The problem with this solution is thatit does not allow the inside of the tire to be inspected for flaws or problems.The String Plug method also does not always seal the puncture in the tireleading to air leakage.
This means that not only will the tirecontinue to leak air, but it will also allow moisture to seep around the objectand into the tire. If left for an extended period of time, the probability thatthe tire can be repaired will be greatly reduced because the moisture willultimately reach the internal steel and fabric cords used to reinforce the tireand possibly cause rust and loss of strength.
The Patch Method
The patch method is used significantlyless, but can be used by some to cut costs. This method reseals the inner linerof the tire, but does not fill the hole itself. This causes the hole to befilled with water and once again allow moisture into the tire. This willultimately reach the internal steel and fabric cords used to reinforce the tireand cause rust and loss of strength.
ThePatch and Plug Method
The patch and plug method is by farthe best way to patch a tire. It seals the inner-liner of the tire and alsofills the path of the injury. This method is essentially a combination of thetwo methods above. The patch on the inside reseals the inner liner to ensure noair can escape, and the rubber filler prevents moisture from entering into thetire itself. This is the method that Big Brand Tire & Service uses.
Whathappens during the repair process of my flat tire?
When a tire is brought in for repairthere is a certain process that is followed so that each tire is repairedproperly. To start off each tire is removed from the rim and inspected insideand out to make sure the tire can be safely repaired.
It is surprising that such a simpleobject such as a nail in a tire’s tread can result in severe damage, but severedamage can be done. Damage done to the tire can also be unseen from theoutside.
After inspecting the tire, the nextstep is to make sure the patch and plug will give a watertight seal, the areasurrounding the hole is cleaned, and buffed. The hole is then cleaned with aspecially designed cutting drill that removes rust and sizes the hole properlyto accept the rubber stem of the patch. The patch and plug stem is theninserted into the hold and pulled and cemented into place, the stem will thenvulcanize (attach itself at a microscopic level) with the tire to help preventmoisture from reaching the tire's reinforcing cords from the outside.
Then the patch is vulcanized to theinterlinear of the tire and pressed into place. Next the vulcanizing cement isspread on top of and around the patch to help ensure a proper air seal. Finallythe tire is filled with air and tested for a proper seal.
If done properly the tire will beairtight and once again safe to drive on the road.
However, it is important to realizethat the tire will never be as strong as it once was. While indoor laboratorytests have shown that freshly punctured and properly repaired tires can stillachieve high speeds, it is not recommended that repaired street tires, orpunctured DOT-legal competition tires and racing slicks be used for trackevents.

Doyou patch run-flats at Big Brand Tire?
For safety reasons, we do not patch run-flats. Due to theconstruction of a run-flat tire, there is no way for us to determine theintegrity of the tire. This becomes especially important if the customer gets anotherhole in the tire and is forced to drive on the tire again.
