And how to fix it for under $40
If you’ve been towing a camper without a tire pressure monitoring system (TPMS), you’re not alone — but you are taking a serious risk every single time you hit the highway.
Here’s the truth most RV owners don’t want to hear: a tire blowout at highway speeds can flip your camper. And the scariest part? You’ll never feel a slow tire leak from inside your tow vehicle. By the time you notice something is wrong, it’s already too late.
Why a TPMS Is Non-Negotiable for RV Towing
Millions of RV owners tow every season without real-time tire monitoring. It feels fine — until it isn’t. Tires don’t always blow suddenly; they often leak slowly and silently. The air pressure drops, heat builds up, and then — on a busy interstate — everything goes wrong at once.
The good news? You can eliminate this risk entirely for about $40. There’s truly no excuse left.
Step 1: Check and Correct Your Tire Pressure First
Before installing any monitoring system, make sure your tires are properly inflated. You might be surprised how low they’ve gotten.
A reliable tire inflator — like the DeWalt tire inflator — makes this easy. Simply connect it to your tire valve, read the current PSI on the display, and set your target pressure. The inflator automatically stops when it hits your target, so you don’t have to hover over it. Check the sidewall of your tire for the maximum PSI rating, and inflate accordingly.
It’s a good idea to check tire pressure before every trip, not just when you install a new monitoring system.
The DeWalt Tire Inflator is a compact, powerful tool that quickly tops off your RV and vehicle tires with precise, automatic shut-off. I never travel without it—because catching and fixing low pressure early is one of the easiest ways to prevent a dangerous blowout.
Step 2: Install the Tymate TM7 TPMS
The Tymate TM7 is an excellent, affordable tire pressure monitoring system that works on any tires — whether you have two or four. Here’s what makes it stand out:
- No wiring. No installation. This is the biggest selling point. Many TPMS units require complicated setup or dashboard mounts. The TM-7 plugs right into your cigarette lighter/12V outlet.
- Real-time PSI and temperature monitoring. It doesn’t just track pressure — it monitors tire temperature too. Heat is often the trigger for sudden blowouts, so this dual monitoring is critical.
- Instant alerts. The system will alert you the moment pressure starts dropping or temperatures spike — giving you time to pull over safely.
- Comes with four sensors. Even if you only have two tires, the kit covers you for future vehicles or trailers with more.
Anti-Theft Sensors
Each sensor screws directly onto your tire valve stem. The kit also includes optional anti-theft hex nuts that lock the sensors in place so they can’t be easily removed. A smart add-on worth using.
The Tymate TM7 TPMS is an easy, plug-and-play tire pressure monitoring system that tracks your RV’s tire pressure and temperature in real time, alerting you instantly to slow leaks, fast leaks, or overheating. You won’t know there’s a problem until it’s too late, and this gives you a chance to stop it before it turns into a dangerous blowout.
What This Setup Will Cost You
| Item | Approx. Cost |
|---|---|
| Tymate TM7 TPMS | ~$40 |
| DeWalt Tire Inflator | ~$130 |
| Your peace of mind | Priceless |
The Tymate TPMS alone is the critical purchase here. If you already have a tire inflator, you’re looking at a cheap safety upgrade that could save your RV — or your life.
Frequently Asked Questions
Do I need a TPMS if my camper only has two tires? Yes. Blowouts happen on single-axle trailers just as often, and the consequences are just as severe. The Tymate TM7 works perfectly for two-tire setups.
Will I feel a slow tire leak while driving? No — and this is the danger. From inside a tow vehicle, you almost never feel gradual air loss in trailer tires until the tire is critically low or has already failed.
Do I need to mount the monitor on my dashboard? Not with the Tymate TM7. It plugs into the 12V/cigarette lighter port, so it doesn’t add any dashboard clutter. Pull it out when you need it, store it when you don’t.
What PSI should I set my camper tires to? Check the sidewall of your specific tires for the maximum PSI rating. This is your target inflation pressure for towing.
Bottom Line
If you’re towing a camper right now without a tire pressure monitoring system, you’re relying on luck. Luck runs out. A simple gadget like the Tymate TM7 gives you real-time visibility into your tire pressure and temperature at all times — and that early warning could be the difference between pulling over safely and a catastrophic highway blowout.
Install it before your next trip. It takes less than 10 minutes and zero tools.
