Customer Review: “I wanted to have a reading on my trailer tires and saw this product. Read some reviews and thought I would still give it a try. Very easy to read the size is good and the solar power is nice to have for long trips. Although I don’t use it a lot it is nice to know the pressure and temp of the tires.”
7. Tymate TM5 TPMS with a Large Color Screen, 4 External Sensors, and 5 Alert Modes

Complete Buying Guide for Best Aftermarket Tire Pressure Monitoring System
Essential Factors We Consider
Choosing the right aftermarket TPMS boils down to a few key things. First, think about sensor type: external sensors screw onto the valve stem and are easy to install, but can be stolen. Internal sensors go inside the tire and are more secure, but require professional installation. Next, look at the display monitor. Do you want a color screen, a large size, or solar charging? Also, check the alarm modes. More alarms (for low pressure, high pressure, high temperature, rapid leaks) mean better safety. Finally, consider power source: solar is great for set-and-forget, while plug-in models are always on but use your car’s port.
Budget Planning
You can find a decent basic system for around $50. For $50 to $100, you’ll get better features like solar charging, color displays, and more sensors. High-end systems for large RVs with 10+ sensor capacity can cost $150 or more. Our best budget pick, the Tymate TM2, shows you don’t need to spend a lot for quality. Remember, a good TPMS is an investment in safety that can prevent costly tire blowouts and improve fuel efficiency.
Final Thoughts
The best system is the one you’ll actually use and that fits your vehicle. For most passenger cars, a 4-sensor system with solar or plug-in power is perfect. For RVs and trailers, consider capacity and features like flow-thru sensors. Weigh the pros and cons of each model against your specific needs. All the systems we’ve reviewed are top performers in their category.
Frequently Asked Questions
Q: How do aftermarket TPMS systems work?
A: They use small sensors attached to each tire’s valve stem. These sensors measure pressure and temperature, then wirelessly send that data to a display unit inside your vehicle. The display shows you real-time readings and sounds an alarm if something is wrong.
Q: Are they easy to install?
A: Extremely easy for most models. External sensors simply screw on in place of the valve caps. The display unit usually plugs into a 12V socket or mounts on the dash with adhesive. You can typically set it up in under 10 minutes with no tools.
Q: Can I use one system for both my truck and trailer?
A> Yes, but you need a system with enough sensor capacity. Models like the Tymate TM12 support up to 12 sensors, so you can monitor your truck and trailer tires simultaneously. Some systems allow you to pair two sets of sensors for different vehicles.
Q: Do the sensors need battery replacement?
A> Yes, but not often. External sensor batteries usually last 1-3 years depending on use. They are typically CR1632 or similar batteries that are easy to replace. The display unit is often rechargeable via solar or USB.
Q: Are these systems accurate and reliable?
A> The best ones, like our top picks, are very accurate, often within +/- 1 PSI. They are reliable for daily driving and long trips. Look for models with good customer reviews and waterproof sensors for peace of mind.
Investing in an aftermarket tire pressure monitoring system is one of the smartest, most affordable safety upgrades you can make for your vehicle.
