Question about run-flat tires
Got the dreaded message while ona trip. L.F. tire flat on the DIC....
Got out and looked..didn't look flat to me.. This is my first experence with a run flat tire so i didn't know what to expect. Tire pressure never dropped from 33 pounds on the monitor. i thought it was a malfunction in the sensor.
Rode around a little longer and stopped again. Still looked good to me. Then found a very small nail in the tire. Didn't look like it was leaking down from the nail at all. Carefully drove it home without any problems...
Question one.. Is the pressure supposed to drop when you get a nail in it Mine stayed at 33 lbs on the D.I.C.
Question two.. Can the Goodyear run-flat be plugged or patched like a regular tire ?
Thanks for any help or advice !

Re: Question about run-flat tires (Corvette Poor)
The car has to be moving faster than 14 MPH for the sensors to work.
If you were driving while you checked all 4 tire pressures and none of them were low, then you may have a sensor problem.
Good Luck.

Corvette Poor,
I recently had a blow-out and got the same message on my D.I.C.
"Left Front Tire Flat"
And the Tire Pressure Sensors showed the pressure to be 0 psi.
Even though I had a big cut in the sidewall due to a road hazard, it only looked slightly under inflated.
An accurate tire pressure guage is the best way to check.

Yup. Patch it, and it'll be fine. I had a utility knife in my tire, and it was still patchable since it was through the tread and not the sidewall. Your psi may not have dropped if there was no air escaping from the nail. Even with nearly 0 psi, I could not tell my tire was flat when looking at it...just looked a little low.

People plug EMT's all the time. It is the safest tire in the world to plug. The EMT is just a regular tire design with very thick side walls.

Re: Question about run-flat tires (Corvette Poor)
Hmmmm....the only way your car knows it has a flat is for the pressure to be "0". The DIC will warn you when the pressure drops below 25lbs but it doesn't tell you you have a flat.
Now, to patching the run flats - just did it but kept the tire for a spare. If you make 100mph runs occasionally :rolleyes: like someone I know, then I would replace the tire. But...a good tire place can plug and patch from the inside...good enough for normal driving.
Good luck on the sensor.....sounds a little fishy. :(
