Is there a downside to running flat tires?
Flat tires are an inconvenience that every driver dreads. However, with the advent of run-flat tires, many drivers feel more secure knowing they can continue driving for a limited distance even after a puncture. But are there any downsides to using run-flat tires? As an experienced auto service provider, I’ll break down the pros and cons to help you make an informed decision.
What Are Run-Flat Tires?
Run-flat tires are designed to allow you to continue driving for a short distance after a puncture or loss of air pressure. Typically, they enable you to travel up to 50 miles at a reduced speed (usually around 50 mph), giving you enough time to reach a repair shop or a safe location to replace the tire.
The Downsides of Run-Flat Tires
While run-flat tires offer undeniable convenience, they are not without their drawbacks. Here are some of the key disadvantages:
- Reduced Ride Comfort: Run-flat tires have stiffer sidewalls to support the vehicle's weight when deflated. This stiffness can lead to a harsher ride compared to traditional tires, as they absorb less impact from road imperfections.
- Higher Cost: Run-flat tires are generally more expensive than standard tires. Additionally, not all repair shops are equipped to handle them, which could lead to higher repair or replacement costs.
- Limited Repairability: In many cases, run-flat tires cannot be repaired after a puncture and must be replaced entirely. This can add to the long-term cost of ownership.
- Shorter Lifespan: Due to their unique construction, run-flat tires may wear out faster than traditional tires, especially if driven frequently on rough roads.
- Weight and Fuel Efficiency: Run-flat tires are heavier than standard tires, which can slightly reduce your vehicle's fuel efficiency and handling performance.
When Are Run-Flat Tires a Good Choice?
Despite their downsides, run-flat tires can be a great option for certain drivers. They are particularly useful if:
- You frequently drive in areas where it may be unsafe or inconvenient to stop and change a tire.
- Your vehicle does not have space for a spare tire, as is common in many modern cars.
- You value the peace of mind that comes with being able to drive to safety after a puncture.
Conclusion
Run-flat tires offer a unique combination of safety and convenience, but they come with trade-offs in terms of cost, comfort, and longevity.

Frequently Asked Questions
Which is better, run flat or regular tires?
In the event of a tire puncture, run flats offer safer handling than regular tires. The reinforced sidewall provides more stability and consistency. More room in the trunk! Since most vehicles equipped with run flats do not come with a spare tire, you'll have a lower vehicle weight and more cargo space.
How bad is it to run on a flat tire?
You may end up needing to replace both the tire and the rim, which will drive up your repair costs. Worse, driving on a flat reduces traction and makes it harder to steer, increasing your risk of losing control. It can also strain your suspension and braking system, leading to misalignment and other expensive repairs.
How long can you run on run-flat tires?
50 miles
Not only do run flats save space in the boot as a spare wheel is no longer a necessity, their ability to drive up to 50 miles after incurring a puncture means motorists don't need to be worried about getting stranded at the side of the road.
Do run-flat tires damage suspension?
You should also note that you may need some changes made to your vehicle's suspension. Because of their stiffer construction, run flat tyres contribute to a vehicle's suspension when fitted as original equipment.
Why do people dislike run flats?
Even when properly inflated, the reinforced sidewall structure is stiffer than the sidewall of a conventional tire. The added spring rate of that stiffer sidewall can be felt over every bump. There is also a little extra mass for the suspension to cope with, which also has an effect.”
Is it OK to drive on run-flat tires?
Much like a spare tire, a run-flat tire has a limited range and a limited speed. Once you know you've lost tire pressure, you should carefully reduce speed to a maximum of 50 mph as soon as possible. Additionally, you shouldn't drive for more than 50 miles on a run-flat once it loses pressure.
Can you change from run-flat tires to regular tires?
Yes, you can! Replacing run flat tires with run flat tires is recommended but not required. If you do choose to swap out your run flats for conventional tires, here are a few things to keep in mind. When switching from run flats to regular tires, you should replace all four tires at once.
Do run-flat tires affect performance?
Run-flat tires may provide less handling and ride comfort when deflated than fully inflated tires. Drivers should anticipate these changes and adjust their driving accordingly.
What are the negatives of run-flat tires?
Limited Distance and Speed: The ability to drive for a limited distance and at reduced speeds after a puncture may not be suitable for all driving conditions. Repair Challenges: Run-flat tyres are not easily repairable, and replacements can be more expensive than conventional tyres.
What is the life expectancy of a run-flat tire?
30,000- to 40,000-mile
Both systems typically have the same 30,000- to 40,000-mile life expectancy as regular tires, though run-flats generally cost 25-to 30-percent more than conventional tires, says VandeWater. The support ring tire contains a separate internal ring that supports a load in a lowpressure condition.
