Breaking Down Run Flat Tyres Advantages And Disadvantages
Run flat tyres may sound like the perfect way to avoid getting stranded on the side of the road. While they have their advantages, run flat tyres arent yet a perfect technology and come with some trade-offs.

What about disadvantages? Run flat tyres are popular in Europe, and many Australians believe that due to the shorter distances between European towns, thats where theyre best suited. Some people also find that run flat tyres create an uncomfortable and bumpy ride due to the reinforced sidewall. Regular tyre prices are also cheaper than run flat tyre prices, and the grip of regular tyres is also considered to be better all around. Run flat tyres may also be a little heavier, decreasing fuel economy and increasing your trips to the bowser. However, this is offset by not having to carry a spare tyre!

Can You Repair A Run Flat Tyre With A Nail In It

Are Punctures In The Sidewall Repairable
In a word, no. More specifically, a puncture that falls outside the minor repair area is not eligible for fixing because of its proximity to the sidewall.
The sidewall is off limits for a straightforward reason. When the tire is in daily operation, this section undergoes a significant amount of stress. Any attempts at making repairs in this area will potentially weaken the structural integrity of the tire.
Another factor is that the sidewall experiences the most flex in the tire. Its unlikely that a repair patch applied here will stay in place for very long, and the tire will fail once again.
One more thing concerning the sidewall is that you should avoid driving any further on a flat tire if you hope to salvage it. Inflation pressure maintains the shape of the tire while driving when that pressure is lost, the tire sidewall is going to be pinched between the wheel rim and the road, so continuing to drive will extend the damage beyond the minor repair area.
In other words, do not drive on a deflated tire while the puncture is within the minor repair area . The tire sidewall could sustain additional damage that renders it beyond repair. The better course of action is to have the vehicle towed or swap the punctured tire out for the spare tire until you reach the nearest garage.
What Exactly Are Run Flat Tyres
The feature that distinguishes run flat tyres is their specially reinforced sidewalls. 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. Usually, you can drive for a maximum of 50 miles at a top speed of 50mph on a punctured run flat, allowing you to get to a tyre centre to assess the damage.
This saves you from having to replace your car tyre at the roadside or call out emergency roadside assistance. As an added bonus, because you dont have to carry a spare tyre with you in your car, you can benefit from a larger boot space and – thanks to the reduced weight – greater fuel efficiency and mileage. Importantly, run flats also make it easier to keep control of your vehicle in the event of a puncture, reducing the risk of an accident.
Because of their reinforced sidewalls, it can be difficult to tell youve got a puncture if youre driving on run flats. This means all vehicles that use these tyres must also have a tyre pressure monitoring system fitted. Often, an alert from this monitoring system is the only thing that indicates to drivers that they have a puncture.
If your car has run flats and your TPMS warns you that youre losing pressure in one or more tyres, its vital that you stick to the speed limit and mileage specified by the manufacturer and get your tyres changed as soon as possible. Your handbook will give you the details of these restrictions.

How Do The Tires Work
The flat run tires come with two mechanisms: the self-supporting system and the support-ring-system. In most self-supporting run flat tires, the walls of the tires are very much reinforced to take the weight of the car in the event of a puncture.
In the support-ring-system there is a very thick ring of hard rubber in the tire that covers the wheel inside the tire. There is space between the inner tire and rim of the wheel, and this rubber is around the rim of the wheel. The air tube runs between the hard rubber band and the inside of the tire. When the rubber tube gets punctured, the air escapes. The rim rests on the rubber that touches the inside of the tire.
Both systems can only be used in cars that have tire pressure monitoring systems. This system alerts the driver as any one of the tubes starts losing air pressure. A run flat tire that comes with a support-ring-system, usually has thinner tubes, as the hard rubber in the tire takes up space. This type of monitoring system is even more important for such tires.
These Are The Pros But Of Course There Are Cons
