Some criminals will target a car’s tires to try and stop the vehicle, but run flat tires help make an effective solution to the problem. A run flat tire is a specialist tire that allows a car to continue driving even after a puncture. The car can only continue for a limited distance at limited speeds, but it’s enough to get the vehicle to safety in many cases.
The main reason run flat tires work is that they have reinforced sidewalls that help the tire keep shape even when deflated. Because the tire keeps its shape better, so the tread of the tire can still contact the road enough for the vehicle to travel.
However, run flat tires don’t come cheap, and they are not indestructible. Punctures and other issues can occur and the cost of replacing a run flat makes it understandable that you might be wondering “can you patch a run flat tire?”. Let’s find out
How are Run Flat Tires Patched?
It is recommended to replace run flat tires after deflation, and many technicians will not agree to patch up a run flat for you. However, some people will still prefer to have them repaired, which can be done depending on the extent and nature of the damage. However, these people face the risk of a blowout or similar if the weakened tires give way.
Can Run-Flat Tires Be Patched?
While traditional tires can often be repaired with patches or plugs if punctured, repairing run-flat tires is more complex. Most tire manufacturers and automotive experts recommend repairing run-flat tires once they’ve been driven on with low or zero pressure.
The internal structural integrity of these tires can be compromised, making them unsuitable for safe repair.
The reasons why run-flat tires are not usually repairable include:
- Internal Damage: Run-flat tires are built with reinforced sidewalls and specialized construction to support the vehicle’s weight after a puncture. Driving on a deflated run-flat tire can cause internal damage that might not be visible outside.
- Safety Concerns: Repairing a run-flat tire driven while deflated could compromise its safety. There’s a risk that the tire might fail, leading to a blowout or loss of control while driving.
- Manufacturer Recommendations: Many tire manufacturers explicitly state that run-flat tires should not be repaired after being driven without proper air pressure.
When Is Repair Possible?
In some cases, if the run-flat tire has not been driven on or has suffered minimal damage, a professional inspection might deem it repairable. If the damage is on the tread area, within a specific size limit, and has not compromised the tire’s internal structure, a repair might be feasible. However, these decisions are typically made by trained technicians on a case-by-case basis.
Safety and Expert Opinion:
Safety is paramount when it comes to tires. If you suspect damage to a run-flat tire or experience a loss of pressure, it’s advisable to:
- Stop Safely: Avoid driving on a deflated run-flat tire for an extended period or at high speeds.
- Inspect Carefully: Assess the extent of damage and consult a qualified tire professional for an expert opinion.
- Follow Manufacturer Guidelines: Adhere to the manufacturer’s tire repair and replacement recommendations.
In conclusion, while run-flat tires offer added security during a puncture, repairing them after driving in deflated conditions is generally discouraged due to safety concerns and potential internal damage. When in doubt, seeking advice from a certified tire professional is crucial to ensure the safety and longevity of your vehicle’s tires.
What if Tire Damage is Too Extensive?
If the damage is too expensive, then it will become too difficult to repair the tire safely. The tire will have lost its shape and strength, which is potentially dangerous if driving at high speeds. If you’re in any doubt, then you should have a new tire installed to help ensure your safety.
Manufacturer Policies
Depending on the tire manufacturer, there will be different policies in place in case of damage. A lot depends on how far the vehicle was driven since run-flat tires have a limited range.
