Non-runflats may harm tire pressure sensor?

[Black04Vert]

A rep at Discount Tires told me that non-runflat tires on some types of cars will ruin the tire pressure sensors if they go flat because the non-runflat sidewall will collapse enough for the sensor to be damaged. Does this apply to the C6 or are the valve mounted sensors deep enough that they are protected by the lip of the wheel?

I don't know how probable it is, but I'm sure it's possible.....

Black04Vert, I have done two C-6 wheel changes all around and installed the sensors myself. They fit close to the wheel and although I could not say for certain I think it would require the tire to be really flat and driven for a long period. Even the non runflat tires for these cars have stiff sidewalls in order for them to carry a "Y" rating (speed).

There is a Forum member named Breyzee (not sure about spelling) that is very knowledgeable about wheels and tires and his opinion is probably much better that mine. I hated the C-5 runflats and took them off as soon as I could. The C-6 are much better and I am back to runflats on the C-6.

Like Fat Bob says, I think they'd have to be really flat, or the sidewall would have to come off the bead or shred for the sensors to be damaged.

A blowout with a rapid loss of pressure would be more likely to create a problem, but with a slow leak the sensors will let you know in advance so you can catch it before a problem gets too bad.

Below is a picture of how they mount in the stock wheel. If you've got them in aftermarket wheels or banded inside you might have more problems.

Thanks Bob, I have read many of your posts but I couldn't remember the exact spelling of your name. I am a wheel nut myself but I thought if you picked this up you could help him with more certainy than I.

Thanks for the info. I've got 15K on my GS2's and I'm down to 2/32 inch of tread left. Non-runflats give me a lot more options.

I have never seen that happen and a huge number of people swap out their runflat tires

The same sensors are used on runflat or non-runflat tires. We provide tire/wheel equipment to the OEM's and they use the same wheels and sensors with different tires all of the time.

Goodluck,

there are also vehicles that come with sensors and non-runflat tires from the factory .... I think your guy needs to learn more about his profession before he spouts off with non-factual useless drivel
