CorvetteBlog continues to be amazed at Run-Flat Tire Technology. Documents received recently speak of the fantastic nature of these tires. For example: "Run-flat tires perform so well without any air that a Tire Pressure Monitor System (TPMS) is used to alert you if a tire has lost pressure."
Consider this caution: "When the low tire warning light is displayed on the instrument panel cluster, your vehicle’s handling capabilities will be reduced during severe maneuvers. If you drive too fast, you could lose control of your vehicle. You or others could be injured. Do not drive over 55 mph (90 km/h) when the low tire warning light is displayed. Drive cautiously and check your tire pressures as soon as you can" (emphasis ours).
Sure, it is presented as a caution, but they are saying in this official document (#1911402) that with little or no air one should not drive faster than 55mph! Is that not incredible?
The following paragraph goes on: "If a tire goes flat, you will not need to stop on the side of the road to change the tire. You can just keep on driving. The shorter the distance you drive and the slower the speed, the greater the chance that the tire will not have to be replaced. If you drive on a deflated run-flat tire for 25 miles (40 km) or less and at speeds of 55 mph (90 km/h) or less, there is a good chance that the tire can be repaired. The tire can operate effectively with no air pressure for up to 100 miles (160 km) at speeds up to 55 mph (90 km/h), but the tire would then have to be replaced. When a tire is filled with air, it provides a cushion between the road and the wheel. Because you will not have this cushion when driving on a deflated tire, try to avoid potholes that could damage your wheel and require replacement of it" (emphasis ours).
Without a doubt: what fabulous technology, and what peace of mind this gives!
