wow prices have really dropped since I bought mine, Xclimation, at that price you have little to lose.
from my experience, the issue is not the TPMS affecting balance, but the associated vibrations on the tire valve stem,
as in it eventually tore my stem apart causing a rear deflation while I was at speed, not fun. two rescues later and
the majority of daylight gone, I had my ST at the tire shop and was taking a taxi home for the night...

I would suggest looking for a sensor inside the tire with its own metal valve stem, keeping in mind
some say the ST wheel is not metal valve friendly.....

I wondering about this because I've heard of people having issues who converted there valve stem to a 90 degree stem and it causing issues. Haven't read it on this forum.

That eBay link shows a tire pressure gauge, not a monitoring system. Very misleading.

Edit... my mistake, the Rand McNally system originally posted was a TPMS, but now not available and the suggested replacement is just a pressure gauge.

I just bought an 2014 ES with the Cyclops TPM, don't like it, hard to read, have to unscrew sending unit to add air, I'm taking it off. I always check my tires every week the old fashion way..

I’m using my Garmin’s system without issues and like.
First I’ve heard to a rubber stem breaking off from a TPS, remedy that with a steel stem I guess.

I have 90 degree stems and use the Garmin TPMS that go to my Zumo 595. Never even thought about tearing the valve stem due to the weight and position.......

I just ordered the Bike Master 90 degree stems, I'm not sure if they will clear the little ridge, I guess yours does?

How the valve sit in the middle of the rim and on each side is a small wall or ridge that the stem has to clear...

I just installed a system I bought off of ebay. It fits good on the S10, I will see how it does over time. The sending units weight 6 grams each, the stock cap weighs 1 gram so a difference of 5 grams. I added a 5 gram wheel weight 180 degrees across the tire so balance will not be affected at all.

Here are the pics, one of the receiver and one of the sending unit on the front wheel. It monitors air pressure in either psi or bar and temperature in either Celcius or Farenheit. You can also set the alarm for high or low pressure and I think high temp as well.

Ok.......was not following you. My bike is back home, I am out of town for work........now it makes sense. Yea, no there are NOT any issues. They are tall enough that it clears before making a right turn.

Some things to consider about many of the TPMS systems that mount outside the wheel on the valve stem:

- The caps are supposed to be lock nut secured, which means when you do ad air, you need to fuss with the wrench every time, twice for each cap, when you take it off and put it on.

- The pressure reading you get when you fire it up is the pressure from the last time you shut it down, not the current pressure. You have to roll ~100 feet or so before you get a current reading. So at the end of the driveway or block, you see you need air, and have to turn around to go take care of it in the garage, break out the tool, etc. (I'm not sure if the Garmin is this way. If not, that might account for it eating batteries.)

- Battery life/design. Some of the valve cap style allow easy replacement of the battery, others require you buy a new sensor as they have sealed batteries.

Only slightly related; Pet peeve about factory TPMS systems, they don't alarm until the tire(s) are already 8-10 psi lower than recommended pressure. The wife's '18 Equinox had the TPMS go off yesterday and was reading 27 psi. Normal pressure is 35 psi for that vehicle. So much for saving fuel! I have to wonder how long she's been driving around on the low pressure. She knows she is supposed to cycle thru the screens and check the tire pressure, but apparently hasn't been doing so. Nagged me about me checking the tires when she got her new car, "you don't have to, it has TPMS". We ended up stopping at a gas station and spending $3 in quarters to fill all four tires back up to 35 psi.

My four wheel vehicles get a mini compressor and sticky strings, just like my bikes. A flat is a flat, and for me, is easier to fix than replace wheel.

The Garmin wheel sensors don't have or require a lock, simply hand tighten them just as a normal stem cap. A lock nut could be back-tightened against the sensor if concerned about theft.
When first turned on, the GPS shows blanks for tire pressure, they go live within 5 feet of rolling the bike and give an audible warning if the pressure or battery voltage (in the sensors) is low.
The GPS also displays a graph for the pressures for the past 8 hours of travel and another graph for the past 8 days.
I'm still using the same batteries originally supplied and installed 70,000 kms ago, but the low voltage warning has been displayed for about a month. Pressure readings are being displayed like normal, I'll replace the batteries when it stops working. Easily replaced without removing the sensor from the wheel.
I'm using steel valve stems I found at Napa, the bottom nut fits perfectly between the front wheel flanges, and between the gap in the rear wheel flange, no modifications to either wheel.

Thought I would add my experience. Just installed this TPMS that I purchased from Amazon. Tested it on a all day ride. Seems to work fine. It doesn't turn on until movement. Updates after a block or so as mentioned in previous posts. A 12mm lock nut must be removed before you can remove the cap. For the price, I like it. We'll see how long it lasts.

I’m currently looking for systems, as well as tire plugging CO2 kits so if I get stuck, I can try to get things working again and get back to a place to patch the tire properly, until I can buy a new tire.

I would love more discussion about this stuff, but I guess the ADV board might be more useful for these multiple format products.

I'd be interested to see, long term, what the results are for those sensors vs a calibrated digital gauge. Is that something you'd be willing to do? Check the pressure once in awhile against a known working gauge?
