Note: Got a thread over in wheels forum, only got 1 reply, thinking I'll get more action here?
OK, here's the deal, just bought a set of rims for my 08, will be buying a set of Non run flats for the new rim's. Being as my sensors will be 9 years old, I'm not sure it's worth breaking down the 08 rim's to pull the sensor's for the new wheels/tires? I know why we have sensor's in the run flats, otherwise some of us might not know that they've lost pressure. But with Non run flat's, I'm thinking your gonna know you've got a flat, the TPMS isn't necessary, although HST, it'll give you a heads up. What would your advice to me be, should I put the sensor's in the Non run flat's..... anyone out there doing just that?
ymmv

Purchased my car last year and found out Mine don't work and I haven't seen any negative results Does that count ?

My belief is TPMS are a good idea even with non run flats. I would like the idea of knowing when I'm losing air pressure as soon as possible.

I wouldn't add a TPMS system to an older car, but since the C6 has the system, why not use it, runflat or not.

Since our vehicles are equipped and programmed for TPMS, I would install them even if running non-run flats. They will let you know if you have a slow leak that you can take care of before the tire goes completely flat. This would be particularly useful on long road trips.

Yeah, I don't think they have anything to do with runflats -- my 2011 Toyota pickup had a TMPS, although not one for each individual tire. But my 2017 T. pickup does have one for each tire, just like the Vette, and no, it doesn't have RFs.

I'm trying to figure out how I made it through the first 60 years of my life without something on my dashboard telling me I had a low tire.

142K on my '08 and about 125K with the OEM sensors. The age is not as important as the mileage, since the sensors sleep shortly after you quit driving.

I also had a blowout on a non-runflat at 60 mph on a mountain curve in the rain. Although the DIC immediately indicated a flat tire, the car still drove well and controlled for about a 1/4 mile while looking for a place to pull off the road. I'd guess that a fairly low pressure would still drive well, since the sidewalls are so short.

I did drive about 8K without sensors at one point. After the blowout episode and knowing how well the car drove with 0 air, I tended to check tires real often.

It's actually one of the few useful car technologies that's been mandated over the last decade. Are there problems? Of course, but it's saved lives. You'd be silly not to use it.

Three of the four on mine are kaput, and have been for about two years, but plan on fixing this shortly.

Without TPMS working....you shouldn't be able to get into competitive mode, etc? I couldn't get into different modes even when I was having intermittent low battery issues with my TPMS sensors....and also almost caused an accident when the active handling was braking on me during cornering due to the TPMS. I wouldn't run without them myself.

I like TPMS. I've had 3 vehicles now with it, none of them (including the Vette) have run flats. Nice to check the pressure on a cool morning, nice to check on a long trip. You can get aftermarket sensors relatively cheaply now.

Something nobody else has suggested is to purchase new TPMS sensors for the new tires/wheels. Don't bother with the old ones. Programming them to the car is a simple process if you have a scan tool or take it to any tire shop and they can link them up for you.

I also agree with the others who said that the light on the dashboard is great. I find that when we go from summer to winter, the temperature change is enough to lower the tire pressure and the TPMS has warned me about it several times.

It would be more important I would think to have them if you didn't have runflats.

Sensors maybe fine. Mine are 12 years old and are on non rf tires.

As an avid tire watcher on my other non-TPMS vehicles, I find the TPMS very helpful. ESPECIALLY since the Vette doesn't have a spare. I'm on non-run flats, but as mentioned earlier, I want to know as soon as possible that there is a problem. With a nail or something in the tire, I'll be able to get to a preferred tire shop while it's still drivable without causing any damage. Due to the short & rigid sidewalls, I'm not sure how obvious it is visually that your tire is low on pressure.
No active TPMS = spare tire in the trunk as insurance on longer trips.

I love mine, had to replace two, so far in 2005, wouldn't drive without them.

Zero_6

Just don't buy them from the stealership, over $400+. I bought mine from a CF vendor for a cheaper price.

door2416

For peace of mind buy new ones for the new wheels as already been suggested.

Thankfully the government is here to tell you that you need it and have to have it. Along with mandatory backup cameras.

The GM TPMS is one of the more useful showing tire pressures on individual tires. That is one area that Ford has always let me down. They just give you a low tire message, and usually not until its WAY lower than it should be, and its up to you to find which one. As mentioned above, on a low profile tire, 15 PSI can look visually just like 30PSI. With the price of aftermarket tire sensors being low, and the possibility of an annoying message or light on the dash if not fixed, I would buy a new set.
