TPMS not installed

[ZooMazda24]

I put a new wheel/tire combination on my 2025 CX-5, and the installer was under the impression that the car did not use sensors in the wheel but instead relied on ABS data (like in the old days), and so he did not inquire about whether to install some TPMS.

The warning light appeared and I read about the TPMS on newer CX-5, I was still OK with that as I see little point in buying sensors that can only tell me that an unidentified tire has a pressure issue.

I visually check tires every drive, and check pressure frequently, as I do in my other less sophisticated cars. I am the TPMS.

Will problems occur in the car's system if I do not install TPMS and leave the warning light to shine?

Why am I wrong to leave my car in this condition?

TPMS has alerted me twice to tires that were damaged and were losing air. In one case I was on a road trip and was able to pull off the highway and put enough air in the tire using a 12v air pump and continue to my destination. The other instance was local, my wife hit a curb and tire was severely damaged and she was able to get to a parking lot. Had there not been TPMS she might have not have recognized that a tire was flat and could have damaged a rim.

I don’t have TPMS on my winter wheels on my 2018 CX-9. No issues other than the light on the dash remaining on. For me that is only 6 month of the year. It is a nice to have and if it was my permanent set i would likely invest in it, but i can live without for 6 months. You might be able to get the tpms sensor from your original wheels and swap them.

Your installer should've swapped them over from the stock wheels to the aftermarket wheels. They owe you a set of sensors.

Are you saying that your tire tech installed new wheels and tires and didn't even notice, or ask, if you had in-wheel TPMS?

"the installer was under the impression that the car did not use sensors in the wheel but instead relied on ABS data (like in the old days)"

In the old days?

The old days are NOW! There are plenty of brand-new vehicles out there with ABS based TPMS.

In some ways the ABS based system is better than the system with individual sensors in each wheel. No batteries to mess with for one thing.

"Why am I wrong to leave my car in this condition?"

You're not wrong, it's your car after all, right? You're just missing out on a safety/convenience feature is all.
