What are the negatives of run-flat tires?
Run-flat tire cons Less responsive handling — run-flat tires can negatively impact handling and responsiveness, making the vehicle feel less agile and maneuverable. Uneven wear and tear — due to their unique construction and potential for driving while underinflated, run-flat tires are prone to uneven wear patterns. Run-flat tires cannot be driven faster than 50 miles per hour and typically offer up to 50 miles of extended mobility. Selected applications, based on vehicle and the run-flat tire design, can range from just 25 miles up to 200 miles.The following include the main advantages of run flat tyres: Continued Driving After a Puncture: This is the most significant advantage. Unlike conventional tyres, run flats allow you to continue driving for a limited distance (usually 30-50 miles) even after a complete loss of air pressure.They last just as long as regular tyres depending on driving style, road conditions, and tyre quality. After a puncture, most Runflat tyres can be driven for about 80 km to 100 km. It is advisable to keep a speed under 80 km/h to reduce heat buildup and further damage.This characteristic means that even when they are punctured, you can carry on driving on them for a limited number of miles and at a reduced speed.

Uneven wear and tear — due to their unique construction and potential for driving while underinflated, run-flat tires are prone to uneven wear patterns.Tires with the runflat tire technology last as long as regular tires do. Namely, the average lifespan for run flat car tires is about 50,000 to 60,000 miles. External factors such as road conditions, driving habits, car problems, and air pressure levels, can greatly shorten tread life.Run-flat tires basically have firm sidewalls.

Do run flat tyres use more fuel?
Run flat tyres are designed with a reinforced sidewall to allow continued driving even after a puncture, but this design comes with trade-offs. Due to their stronger construction, they generally have higher rolling resistance compared to regular tyres, which can lead to a slight reduction in fuel efficiency. Despite the fact that they’re built differently, run-flat tyres still need to be pumped with air and work like conventional tyres to support and spread the weight of the vehicle. When punctured, they’ll lose their air, but due to their structural support, you will hardly notice any tyre deflation.Although not usually recommended, it is possible to repair a run flat tire with a nail in it, depending on where the nail is. If the nail is in or close to the side wall then it can cause damage to the tire walls, making them unsafe to use.Run flat tires have rigid sidewalls that carry the weight of your vehicle after a puncture.
