Best Tire Pressure Monitoring Systems (TPMS) for 2024
The best tire pressure monitoring systems provide real-time pressure and temperature readings for all four tires, alerting you before a low-tire situation causes a blowout or uneven wear. Aftermarket TPMS kits are a smart complement to AXLY's live dashboard, giving you dedicated tire data at a glance.
Maintaining correct tire pressure is one of the easiest ways to improve fuel economy, extend tire life, and stay safe on the road. While AXLY monitors your engine and vehicle systems in real time, adding a dedicated aftermarket TPMS gives you continuous, sensor-accurate tire pressure and temperature data displayed right on your dash — no guessing, no manual gauge checks. Whether you drive a sedan, SUV, or truck, these systems install in minutes and pay for themselves in avoided flats and better gas mileage.

Frequently asked questions
Do I need a TPMS if my car already has one built in?
Most factory TPMS systems only warn you when pressure drops significantly below the recommended level — often too late to prevent uneven wear or fuel economy loss. An aftermarket TPMS shows you exact real-time pressure and temperature for each tire individually, giving you much earlier and more detailed information than the factory warning light.
Are external cap-style TPMS sensors accurate?
Quality external cap sensors are generally accurate enough for everyday monitoring and safety alerts. They can occasionally read slightly differently from a calibrated gauge due to temperature effects, but reputable brands are consistent enough to catch meaningful pressure changes and alert you in time.
Will a TPMS work alongside the AXLY app?
Yes — AXLY monitors engine and vehicle OBD2 data on your phone, while an aftermarket TPMS uses its own separate display or app. The two systems complement each other perfectly: mount your phone with AXLY running and place the TPMS display nearby for full vehicle and tire visibility at the same time.
How long do the external TPMS sensor batteries last?
Most external cap-style TPMS sensors use replaceable CR1632 or similar coin-cell batteries that last roughly one to two years under normal use. Higher-quality sensors include low-battery alerts so you are warned before a sensor goes dark.
Can I use a TPMS on a spare tire as well?
Some TPMS kits support a fifth sensor for your spare, which is a worthwhile option if you want to know the spare is properly inflated before you ever need it. Check the product listing to confirm five-sensor support before purchasing if this feature matters to you.
