Punctures can be annoying. You are in a rush to get to work and suddenly one of your tires is flat . To make matters worse, the spare tire is flat. If you want to avoid this, you should invest in a set of run flat tires. Run Flat tires can be great insurance against punctures, allowing you to get to a convenient place to have your car towed or a tire changed.
Many automakers have phased out the spare tire due to the extra weight it puts on the car. Instead, they are equipped with tire repair kits or run flat tires.
These tires will not leave you lying on the shoulder or force you to remove the spare wheel and change it, avoiding the danger that this or other situations of loss of control of the car entail. However, they are not perfect, as a serious tire failure could put your car out of service without a spare wheel and replacing these tires is costly. Here we are going to tell you what a run flat is and what are the main advantages they offer and their disadvantages.
In the event of a puncture or other type of tire failure, run flat tires have rigid and self-supporting sidewalls that are capable of supporting the weight of the car, allowing it to continue driving on the road with very little air pressure. . They are also sometimes called zero pressure tires. The run flat tires will allow you to drive the car for the next 80 kilometres at a speed of 80 km / h.
Often times, the only indication of a puncture is the car’s tire pressure monitoring system (TPMS) warning light on the dashboard. When it lights up, it will tell you that you are driving with low pressure.
Tires with Run Flat properties use two load bearing systems:
Self-sealing technology is another way manufacturers are protecting their cars from tire damage. For this, instead of the traditional ones or the run flat, they install self-sealing tires. These do not have the strength of the sidewalls that run flat have to continue circulating without air pressure and instead prevent all the air from leaving the tire beforehand.
They have a sealant inside the tire that seals the holes caused for example by nails. The sealant is activated by removing the nail from the tire. With a self-sealing tire, you can keep driving with little pressure loss after a puncture. Its installation is possible in cars that are not equipped with a tire pressure control system.
Consumers should consider the advantages and disadvantages of run-flat tires when considering purchasing a new car or replacing their current tires. Find out below the positives and negatives of run-flat tires versus traditional tires.
Currently, most car models have the option of using tires with run flat properties, although only a minority of car manufacturers offer them from the factory. BMW is a notable exception, offering them in various models, including the 5 Series and the 7 Series. Instead of carrying a spare wheel, all you need is a repair kit.
Another aspect to take into account is the need to install a tire pressure monitoring system . Due to its more rigid construction, the sidewalls do not sag if the air pressure is low. Therefore, it is essential to have a tire pressure monitoring system and check your tire pressure frequently, otherwise you will not know when you have a puncture.
