TM2 RV Tire Pressure Monitoring System, Tire Pressure Monitor with Solar Charge, TPMS with 4 Sensors(Max. 10) & 6 Alarm Modes, New Updated w/Color LCD Display, 0-87PSI for RV/Trailer/Truck/SUV

Recently picked up a new to me older truck that's super bare bones, xl version 2010 ford ranger. My old truck has tpms built into the dash menus, so I like to keep up with the tire pressures as I drive about 60 miles round trip a day. The little sensors screw directly on to the valve stems like caps and tighten down nicely, I don't think they'll ever fall off accidentally. Easy to install and set up. I use a 4 tire hose that fills them all at once, so I know the pressure is exactly the same in all 4 at all times. When I first calibrated the unit they all showed exactly the same psi. Once the sun came up next day, I noticed the pressure and temps were higher on the side in the sunlight, so they're remarkably accurate. Driving at highway speeds, the pressures go up about 5psi by the time I get to work. First day driving it I was hyper sensitive to all the new to me noises and road sounds, and was very surprised to see the tire pressure light come on the dash. Apparently it's got super basic pressure senders in the wheels I was unaware of, and it was not happy at the 25 mile mark. I had my trusty new tpms system installed so I immediately stopped and checked it, pressures and temps all looked good, so I assume the factory sensors need recalibrated or one is damaged or missing. If I hadn't had these installed, I would have been panicked and stopped to check all 4 with a gauge manually. This way I'm able to glance at it and know exactly what's going on in real time, even without stopping. Great for peace of mind. It's got a rechargeable battery inside you can plug in via usbc or leave it in the sun and a little solar panel on top will charge it. I only every drive at night (midnite shift) so I opted to not mount it on the dash, as I think the bright lights it puts out would be distracting. I mounted on the drivers side wall inside the center arm rest. Easy to see from the drivers seat, but pitch black in the dark cockpit, also easy to reach with a usbc cable to charge, although a month in and the battery still shows good charge even leaving it on 24/7. The alarm when a tire gets too high or low is very loud, even inside the arm rest it startled me when one went up higher than expected at highway temps. Overall, I'm super impressed. Has all the features I want and none I don't. Price is great, shipped quickly, seems to work perfectly. I still have to figure out the factory tpms issues as the light still comes on at 25 miles, even tho the pressures are spot on. But with this new system installed, I'll never have to worry about what does that light mean?!!?!? haha. Great purchase, buy with confidence.

So good so far . But like most things today give it a few weeks and it could be a different story.

This is a great alternative to overpriced factory tpms options. Sensors seem very accurate within 1-2psi. Easy setup in a couple minutes and wireless is a nice touch. Takes a minute for the unit to read the sensors when turned on but not bad. Anti slip pad works great on dashboard. Unit is smaller than expected which is a plus. It is discreet and fits anywhere. The screen is dim and very hard to see in direct sunlight but I dont need to see it constantly anyway. It notifies of sudden pressure loss and that is mainly what I needed. Already saved me a few times with a blowout. Solar works well. I have never seen the battery level go down since ive owned it. Anyone giving bad reviews is expecting too much from a system that is priced so low. Seems like people want the capability of a $300+ system and thats just unreasonable.

Might be ok for a small rig, but with my 5th wheel and the distance at 30 feet it wont read anything. Not sure what this is made for but save your money

Took our boat 4 hours away on vacation, mostly interstate. It worked flawlessly and monitored tire pressure and temperature the entire round trip. The sticky pad held it in place. Easy to install.
