The solar-powered tire monitor that lets you tow with total confidence. No app, no batteries, no wires.
Relvo™ TPMS Kit
Caught a slow leak before disaster
Halfway through a 6-hour tow to the campground, the RELVO beeped — my passenger-side trailer tire was dropping pressure. Pulled into a gas station, found a nail, plugged it in 10 minutes. Without RELVO I would have been on the shoulder with a shredded tire and a damaged fender.
No more pre-trip anxiety
I used to white-knuckle every mile towing my fifth wheel. Now I glance at the monitor and know every tire is good. The peace of mind alone is worth ten times the price. Wish I had this years ago.
Finally, no batteries to deal with
I went through two other TPMS systems before RELVO. Both had sensors that went dead after a few months because the coin batteries died. Solar sensors? Genius. Set it up once and forget about maintenance forever.
Saved my travel trailer on its first trip
Brand new trailer, brand new tires. Twenty miles in, the RELVO caught a temperature spike on the left rear. Turned out the bearing was going bad and overheating the tire. Caught it before a blowout that would have destroyed the whole wheel well.
My wife insisted we get this
After our first blowout on I-40 — two hours on the shoulder, traffic screaming past, kids in the truck — my wife said we’re never towing again without a monitor. RELVO was the simplest one to set up and it just works. Every trip, every time.
Best $50 I ever spent on my RV
I’ve spent thousands on my rig and this little monitor might be the smartest purchase of all. Knowing my tire pressures and temps in real time while I drive — no phone app, no subscription — it’s exactly what this should be. Simple and reliable.

Stop Worrying About the Tires You Can’t See
Every mile you tow, your trailer tires are invisible to you. A slow leak, a building hotspot, a tire losing pressure you won’t feel it until it’s too late.
Real Towing, Real Protection
"I used to walk around my trailer with a hammer at every stop, thumping each tire like my dad taught me. Now I just look at the screen. Pressure's good, temps are normal, keep driving. My wife says I shaved 15 minutes off every fuel stop. Honestly the best part is just not worrying about it anymore — I actually enjoy the drive now."
"The solar thing is what sold me. My last TPMS had batteries die on me mid-trip and I had no idea a sensor was offline. That won’t happen with RELVO. Set and forget."
"I was 200 miles from home when RELVO caught a 12 PSI drop on my rear axle. Pulled over, found a nail, and fixed it in a parking lot instead of on the side of a highway. This thing literally saved my trip."
"After two blowouts in one season I was done taking chances. RELVO was the easiest system I’ve ever installed — five minutes and I could see every tire. Haven’t had a surprise since."
"On a two-lane stretch through West Texas. no cell service, 100 degrees the RELVO alarm went off. Right rear tire was climbing in temperature fast. I pulled into a dirt turnout, checked it, and the tire was bulging at the sidewall. Swapped to the spare in 20 minutes while it was still intact. If that thing had blown at 65 mph with my family behind me, I don't even want to think about it."

Your Journey Ahead
See what the towing experience is like with Relvo
Phase 1
Unbox & Install
Screw on your sensors by hand, and mount the solar monitor on your dash. Total time: 5 minutes. No tools, no pairing, no app download.
Phase 2
The First Drive
Pull out of the driveway and watch every tire's pressure and temperature appear on screen in real time. That knot in your stomach you didn't know you had? It's already loosening.
Phase 3
The Pay Off
A slow leak. A hot tire. A pressure drop you never would have felt from the cab. RELVO catches it, you pull over calmly, and what could have been a $5,000 blowout becomes a 10-minute fix at a gas station.
Phase 4
Tow Like a Different Person
No more thumping tires at rest stops. No more white-knuckling on the highway. No more wondering what's happening behind you. You just drive and RELVO watches what you can't.
One Monitor. Every Vehicle Protected.
Travel Trailers & Fifth Wheels
+
The most common blowout victims. OEM trailer tires are notorious for failing without warning — and you can’t feel it from the cab. RELVO catches pressure drops and temperature spikes before they turn into roadside disasters.
Boat Trailers
+
Salt, sun, and long sits between launches wreck trailer tires from the inside out. RELVO monitors the damage you can’t see — so your next launch day doesn’t start with a blowout on the ramp road.
Horse & Livestock Trailers
+
When you’re hauling live animals, a tire failure isn’t just inconvenient — it’s dangerous for everyone involved. RELVO gives you the early warning that lets you pull over calmly, not in a panic.
Utility & Work Trailers
+
Heavy loads on rough roads push tires to their limits. RELVO reads up to 144 PSI and monitors temperature in real time — built for the trailers that work as hard as you do.
RVs & Motorhomes
+
Your rig is your home on the road. A single tire failure can mean thousands in damage and days stuck waiting for repairs. RELVO supports up to 18 sensors — enough for your motorhome and your toad.
Older Trucks (Pre-2008)
+
No factory TPMS? No problem. RELVO gives your old workhorse the same tire monitoring tech that comes standard on new trucks — for a fraction of the cost.

Frequently Asked Questions
How is RELVO different from other tire monitors?
+
Three things set RELVO apart:
1. Solar-powered sensors. Other systems use coin batteries that die every 6-12 months. A dead sensor can’t warn you — and most people don’t realize one went silent until it’s too late. RELVO’s sensors charge themselves.
2. No app required. Your tire data is right on the dash monitor. No phone to charge, no Bluetooth to pair, no app updates, no cell signal needed.
3. Price. Premium TPMS systems cost $200-$400+. RELVO delivers the same real-time pressure and temperature monitoring for a fraction of the cost — backed by a lifetime warranty.
What rigs does RELVO work with?
+
RELVO works with any vehicle or trailer with standard valve stems. That includes travel trailers, fifth wheels, motorhomes, boat trailers, horse trailers, utility trailers, dump trailers, toy haulers, and trucks (including pre-2008 trucks with no factory TPMS).
The system reads up to 144 PSI and supports up to 18 sensors — so it handles everything from a small utility trailer to a Class A motorhome towing a car behind it.
What does the monitor actually show me?
+
The RELVO monitor displays real-time tire pressure (PSI) and temperature for every sensor. You see all your tires at a glance on one screen.
If pressure drops below your set threshold, or if temperature spikes above normal, the monitor sounds an audible alarm and highlights the affected tire. You’ll know which tire, what’s wrong, and how urgent it is — before it becomes a blowout.
What if I’m not satisfied?
+
Every RELVO kit is backed by our 60-day money-back guarantee. Try it on your next trip. If it doesn’t give you the peace of mind we promise, send it back for a full refund — no questions asked.
We also include a lifetime warranty on every kit. If any component fails, we replace it. We’re not going anywhere, and neither is your protection.
