Is it absolutely necessary to install tire pressure monitors on my winter wheels? Will the cars operate any differently if the sensors are not in place?

I do not want to take the existing sensors out of my summers, and don't like the idea of spending the $700 the dealer wants for additional sensors.

Thanks in advance.

 

On my CTS-V it doesnt make a difference.

Other cars may differ I'm sure. You may not be able to get into competition/race mode with some possibly.

 

First of all, $700 is CRAZY money for new TPMS. Out of this world.

Secondly, no, TPMS isn't a necessity for winter wheels. My car came with TPMS on the stock wheels and I kept the system when I got new tires but I ran without TPMS on my summer wheels for the last 4 months. Only negative about that was that the tire pressure light was on. If you can deal with that, I wouldn't bother with TPMS.

 

Like Alex said, the light will remain on all the time (and you'll get a warning at every startup). Personally, I think they're a good idea, plus the light would annoy me. Check with Damon, our Tire Rack rep - he'll get you a better deal on sensors.

 

No but the warnings are annoying. Depending on the car there may be ways to get around it though.

 

Have a couple customers that did not go with TPMS sensors on there 997.2 last year.
No issues besides being dealing with the warnings and lights.

 

$700! I have them for just over $400! You don't have to have a TPMS system in order to run winters. You'll just have the light on the dash is all.

Please call me if I can help. I have several cheap winter wheels for this car.
