No, you don't automatically need new TPMS sensors just because you're getting new tires. Your existing sensors will typically outlast several sets of tires as long as they're still functioning properly. New tires and new sensors are two separate maintenance needs that sometimes overlap.
Here's why the two get confused so often. TPMS sensors are mounted on the wheel itself, not built into the tire, so swapping tires doesn't wear out or damage a healthy sensor. What does matter is timing. Since sensors run on non-replaceable batteries that typically last five to ten years, if your Jeep is due for new tires around the same time your sensors are approaching that age range, it can make sense to have them checked and possibly replaced together, since the tire is already off the wheel and being handled by a technician.
There are a couple of situations where replacing a sensor alongside a tire job is genuinely a good idea. If your technician notices a sensor with a weak or dying battery during the tire swap, that's a smart time to replace it rather than waiting for the dashboard light to come on later, which would require a second appointment. Similarly, if a sensor's valve stem seal looks worn or cracked, replacing that small rubber component during a tire change helps prevent slow air leaks down the road, even if the sensor itself is fine.
What you shouldn't feel pressured into is replacing sensors that are working perfectly well simply because you're buying new tires. If your current sensors are reading pressure accurately and communicating properly with your Jeep's system, there's no functional or safety reason to swap them out early. A trustworthy shop will check each sensor's condition and battery status during your tire installation and will only recommend replacement for those that actually need it.
