Yes, run-flat tires can be repaired, but it depends on the extent of the damage and the manufacturer’s recommendations. Flat tires can be a frustrating inconvenience, especially if you don’t have a spare tire or the tools to change it.
Run-flat tires were designed to prevent this problem, allowing the driver to travel certain distances even after a puncture. However, the question of whether run-flat tires can be repaired is a common one, with many car owners eager to know if they can save money by repairing rather than replacing them.
Before diving into the answer, it’s helpful to understand what run-flat tires are and how they work.
Understanding Run Flat Tires
What Are Run Flat Tires?
Run flat tires are a type of tire designed to allow you to continue driving safely, even after a puncture or a leak. These tires have reinforced sidewalls that keep the tire intact and prevent it from collapsing or bursting.
The idea behind the design is to allow you to drive for an additional distance, at a slower speed, usually around 50 miles after a tire loses air.
Advantages Of Run Flat Tires
If you’re considering switching to run-flat tires or wondering if it’s worth spending the extra money, here are some advantages to consider:
- Safer option: Run flat tires have a reinforced sidewall that allows you to drive to a safe place if you experience a puncture or a leak.
- Convenience: With run-flat tires, you don’t have to stop every time you have a flat tire. You can continue driving to the nearest auto repair shop or tire dealer for a replacement.
- Increased trunk space: Because you don’t have to carry a spare tire, you have more room in your trunk for other things.
How They Work
Run flat tires use two types of technology, self-supporting and auxiliary supported.
- Self-supporting: Self-supporting tires have reinforced sidewalls that enable them to maintain their shape and support the vehicle’s weight even with no air pressure, allowing you to drive for a limited distance at lower speeds.
- Auxiliary-supported: Auxiliary-supported tires have a support ring attached to the wheel, which supports the weight of the vehicle in case of a flat tire. This ring is made of a hard rubber or composite material and is attached to the wheel by special pins or locks.
Both types of run flat tires are designed to provide enough mobility and safety to drive to a repair facility or local dealership for tire replacement.
Types Of Run Flat Tire Damage
Can Run Flat Tires Be Repaired?
Run flat tires have been designed to operate even with a completely flat tire, enabling drivers to travel a short distance to a service station or to their home. However, run flat tires can still sustain damage that requires repair or replacement.
In this section, we will discuss the different types of run flat tire damage, including sidewall damage, puncture damage, and tread damage.
Sidewall damage is common in run flat tires and can be caused by hitting hard objects on the road. The sidewall is the part of the tire that supports the weight of the vehicle, so any damage to this area will compromise the tire’s structural integrity.
If you notice any bulges, cuts, or bubbles on the sidewall, it is best to replace the tire immediately as it cannot be repaired.
Punctures are another common issue with run flat tires, just like with regular tires. Sharp objects on the road such as nails or screws can puncture the tire, causing a slow leak or a sudden blowout. If the puncture is within the tire’s tread area and not too large, it may be possible to repair the tire.
However, if the puncture is on the sidewall, the tire will need to be replaced.
The tread is the part of the tire that makes contact with the road, providing traction and grip. Over time, the tire’s tread can wear down due to regular use or if the tire is not rotated regularly. If the wear is uneven, this can cause vibrations and reduce the tire’s ability to handle well on the road.
If the wear is too severe or if there is any cracking or bulging in the tread area, the tire will need to be replaced.
While run flat tires are designed to be much more durable than regular tires, they can still sustain damage that requires repair or replacement. It is important to regularly inspect your tires for any damage, as driving on a damaged tire can be dangerous and lead to further damage to your vehicle.
So, make sure you replace the tire immediately if you notice any damage to the sidewall, tread, or if you experience a sudden loss of pressure.
Can Run Flat Tires Be Repaired?
Run-flat tires are becoming increasingly common due to their many advantages, including safety, convenience and the ability to keep your vehicle moving even after a puncture. However, many drivers still wonder if they can be repaired once they are damaged.
We will discuss factors to consider when fixing flat tires, the limitations of repairing run-flat tires, and oem recommendations on repairing run-flat tires.
Factors To Consider
Before repairing a flat tire, there are several factors to take into account. The following are some of the key issues to consider before repairing a run-flat tire:
- The location of the tire damage: If the puncture or damage is on the sidewall or shoulder, repairs are not recommended.
- The extent of the damage: Reparability depends on the size and nature of the damage. If the damage is too severe, you may need to replace the tire.
- Age of the tire: Run-flat tires that are older than six years or that have been driven for over 50 miles after going flat are not repairable and should be replaced.
- Tire type: Different run-flat tire manufacturers have their own guidelines for what types of damage can be repaired. Look closely at the tire manufacturer’s recommendations to determine whether to repair or replace a flat tire.
Limitations Of Repairing Run Flat Tires
Run-flat tires are reinforced with sidewall stiffeners that allow the tire to support the vehicle’s weight when the tire is flat. This construction method means that the tire can withstand the weight of the vehicle without air pressure. However, it also presents challenges when it comes to repairing the tire without compromising the tire’s integrity.
The following are the limitations of repairing run-flat tires:
- Only punctures up to a maximum of ¼ inch diameter can be fixed, and the damaged area should be at least 1 inch from the sidewall.
- You cannot fix run-flat sidewall punctures because of the extra-strength reinforcement material present in the sidewall.
- Repairs on the shoulder of run-flat tires can cause a reduced load-carrying capacity.
- Repairs that involve plugging or a temporary patch in the tread area are not recommended. A permanent repair patch on the inside of the tire must be used.
Oem Recommendations On Repairing Run Flat Tires
Original equipment manufacturers (oems) have some recommendations for repairing flat tires as they have access to information about their specific tires to provide guidance to drivers. These guidelines are based on the tire’s construction and specific performance characteristics. Here are some oem recommendations for repairing run-flat tires:
- Bmw recommends that run-flat tires should only be repaired once with a rubber plug and patch.
- Michelin advises against repairing any run-flat tire for reasons of safety and performance.
- Goodyear recommends that only small puncture repairs be made to run-flat tires, and that repair should be done within one hour of the incident.
- Pirelli advises against repairing run-flat tires in the sidewall or shoulder areas. Repairs to be done by a qualified tire professional.
