A flat tire in armored cars will happen at the most inopportune place and time. A majority of the people will call for roadside assistance. Even if you know how to change the spare, it is dirty work and there is a great chance that you are not properly dressed for it. However, at times, your car might not even have a spare or you might not know how to use the repair kit.
In such a case, you can enter the run-flat tire. Zero-pressure or run-flat tires will support the weight of the vehicle for a short period of time. This will offer the driver with 100 miles job of range to find out a repair shop. Even though this might sound like the perfect solution, car shoppers and car owners should know about the trade-offs.
Run-flat tires are known to be standard on 12% of the new vehicles. Conventionally, it has been used by the carmakers on most sports cars. However, in recent years, they have also started using it in the other cars like armored cars. As a matter of fact, run-flat tires are the original equipment on several sedans.
The common kind of run-flat tire technology that is used today is the self-supporting tire. The sidewalls of the tire is heavily reinforced for supporting the vehicle when he air pressure is low or when the flat tire lost all the pressure.
- You can drive on a flat tire: The main benefit of self-supporting tire is that it will enable you to keep driving the armored cars on a flat for around 100 miles after all air is gone. You do not have to get out of the car in cold or the rain. Drivers will reduce the speed about 50 mph in order to get the maximum range. The manual of the owner will have the exact figure for each vehicle application.
- Better Stability after Blowout: Since this tire of the armored cars will be able to support the vehicle for several miles without air or even a sudden deflation will result in less weight transfer and will tread destabilization. Handling and steering is going to remain normal.
- Lower Vehicle Weight: With the removal of the spare wheel and the tire repair, the vehicle weight should go down. However, it is not quite like you expect as the flat weight more than the conventional tires because of additional sidewall reinforcement.
- No Spare: The cars are equipped with run flat doesn’t carry any spare tire and wheel. This means that they do not have tools or jack. As a matter of fact, getting rid of the spare tire and then reallocating the space to something else is the reason why car-makers offer run-flats.
- Reduced Tread Wear: People replaced the run-flat tires sooner than the owners using conventional flat tires. Tiremakers tend to put soft tread compound on run-flat tire for countering the hard ride.
- Blowout is Still Possible: If a driver of the armored cars fails to pay attention to the warning and drives beyond the zero-pressure range, the tire might start to disintegrate. Moreover, if the puncture has occurred on the sidewall and the tire hits a big object, the driver will have to call a tow truck.
