With the help of cutting-edge technology, automotive brands are always working to improve car systems and parts. In the process, tires also went through several advancements that improved their functionality and stability on roads. The newest vehicle models from many automakers, including BMW, Mercedes, and Audi, feature run-flat tires.
Here is a detailed explanation of the differences between run-flat tires and normal tires.
RUN FLAT TIRES
The run-flat tires are stiff without compromising the safety of the car occupants. Moreover, drivers can cover a certain distance with a puncture in these types of tires.
There are two primary types of run-flat tires, both working slightly differently:
SELF-SUPPORTING RUN-FLAT TIRES
This run-flat tire type has a sidewall construction reinforced inside. This construction controls the air loss from the tire in case of a puncture. Hence, it allows a few extra miles to be covered with a flat tire.
SUPPORT RING RUN-FLAT TIRES
A support ring of hard rubber inside the run-flat tires inside helps in supporting the car’s weight and preventing air loss.
It is a fact that run-flat tires can only be equipped in vehicles with a tire Pressure Monitoring System (TPMS). The TPMS senses the inflated tire and alerts the driver instantly. Moreover, the driver can drive at a speed of around 50 to 80 km/h and 50 to 100 kilometers with a punctured run-flat tire, depending on the tire manufacturer’s guide.
Let’s have a look at the pros and cons of run-flat tires:
ADVANTAGES OF RUN-FLAT TIRES
The following are the advantages of run-flat tires:
- Allows driving on a flat tire up to 100 kilometers
- Better stability and grip with punctured tires
- Reduced vehicle weight as the run-flat tires are lighter than the normal ones.
DISADVANTAGES OF RUN-FLAT TIRES
Alongside advantages, there are the following disadvantages of run-flat tires:
- Reduced tread life due to running on the underinflated tires
- They cost more than normal tires
- A tire pressure monitoring system is must be needed before installing run-flat tires
- Less availability due to high costs
The most widely used tires are normal tires, also known as standard tires. The main difference between run flat and regular tires is that regular tires restrict driving with a flat or punctured tire. Whereas, standard tires are also made differently since they lack side walls that keep the tire’s air pressure constant when it is punctured.
DIFFERENCE BETWEEN RUN FLAT AND NORMAL TIRES
Although both tires are designed differently. The following are the differences between run flat and normal tires:
- Normal tires cost less than run-flat tires
- Conventional tires go flat when punctured while the run flats allow driving some distance with punctured tires.
- Normal tires provide a smoother ride and better handling than run-flat tires
- Run flat tires can’t be repaired whereas normal tires can be repaired easily
- There is no spare tire with the new car models that come equipped with run-flat tires.
CAN YOU REPLACE RUN-FLAT TIRES WITH NORMAL TIRES?
The answer is yes, one can replace run-flat tires with normal tires. That said, with flat tires, car drivers won’t have to worry about flat tires as the car can cover a few kilometers.
