That's a really great price on the steelmate, I think I paid over $200 when I bought mine a couple years ago.
Did the Tenere wheels have to be modified to fit the steel stems/valves?

Re: TPMS tire valves with steel stem

Thanks for all the input. I've been giving it some thought and I suspect they don't want you to use them on rubber stems because of possible failure from the torque applied to tighten them up and undo them. I doubt very much that centrifugal force is going to be a problem. I'll be looking to get steel stems fitted.

Re: TPMS tire valves with steel stem

Did anyone figure out which steel stems work? I finally installed my steel mate TPMS yesterday. I'm just worried about tightening the sensors too many times after airing up and twisting the stems off with my sausage fingers.

They look the same as car ones

TPMS Safety Range Settings

What is the appropriate High Pressure setting for a TPMS, since the Owners manual specifies the cold reading?
Front @ 33psi, Rear @ 36-42psi depending on load.

Likewise the TPMS has a Max temp warning. What's an appropriate High Temp setting for standard Battlewings? (front and rear)
I have a Tire Guard TPMS.

Re: TPMS Safety Range Settings

I think the high temp warning is irrelevant. I have my low set at 25 for both tires. Couldn't tell you if I set the high at a specific number. If I did it was just a non-reachable setting. I like mine because I know right away when I start my bike if I have a low tire with no guessing. No need to check with a gauge before every ride.

Re: TPMS Safety Range Settings

I just monitored the normal high pressure and temperature readings when I knew the tires were properly inflated and under various conditions. I then set the alarms a few PSI higher and the temperature about 10 degrees F higher than anything I'd seen. Totally arbitrary. There is a rule of 10% PSI increase from cold to fully warm but both my ST1300 and Super-T will exceed that on occasion, even with tires inflated to maximum recommendations in the manual.

Re: TPMS Safety Range Settings

What TPMS system are you using.

Did you have to fit metal valve stems?

Tire Guard TPMS. Previous owner put on steel stems. I have a "T" on the rear already, and one to go on the front at the next tire change. The T let's you adjust pressure without removing the "locked on" sensors. Much more convenient.

I'm using the Orange Electronics one. The sensor is built into the valve stem inside the wheel.

Given the additional weight of the sensor on the end of the stem, the centrifugal forces may be an issue. I would go with the manufacturer requirements. Obviously the forces escalate with higher speeds, which would be the least desirable time for a stem failure.

Re: TPMS Safety Range Settings

Sorta. Tires/wheels occasionally change rotational speed almost instantaneously. For example, when off-road with the TCS off and you hit the throttle the tire can go from zero to top speed. Same for having the ABS off and skidding while moving fast.


A rubber stem may not be strong enough to hold the forces which act on the TPMS sensor block, tearing the stem and suddenly deflating the tire.

Agree on the sorta. It has been a while since my engineering Dynamics class, but one thing I do remember is that wheel dynamics were less intuitive until you looked at it in a particular way. If you are going 70 mph, the bottom of the tire is actually stationary as it is in contact with the stationary road surface. The top of the tire is actually going 140mph, twice the vehicle speed. For every rotation of the wheel, the speed goes from zero to max, back to zero. Given the valve stems are closer to the center of the wheel than the outer edge the impact would be less.

So- Just to preface this post- I have read forum input on TPMS and wanted to encapsulate a review post on what products work for everyone in an effort to make it easier for a member here to make the best decision on TPMS. Please contribute all factors of your decision in your eventual purchase. I know alot of guys who went with RRR Tools, Garmin to name a few, but I kind of get lost trying to sift threw the commentary on what works best- for example, an internal apparatus versus an external one OR the shelf life of the battery system a product uses OR whether pressure and temperature are necessary. I appreciate any input on your decision and purchase as I am trying to come to a decision to replace tires this spring

While I like the Blue tooth interface to my phone (I use my phone for GPS and everythign else on my bike), I'm not really thrilled with the Fobo Bike units ( https://my-fobo.com/Product/FOBOBIKE ). The Pressure seems to swing a good bit more than I acutally observer when the tires warm up and while sitting in my garage with the bike cold, neither will report the same temperature or the temperature of the garage.. there is no way to calibrate this and I'm not sure if the temperature not reading accurately plays into any sort of calculation in it's pressure.

Bottom Line: I don't trust that they are accurate for pressure or temp, but they do seem to let you know if you've had a sudden drop in pressure, so I only use them for that and check pressure with a gauge still.

I've always wondered how those valve cap type sensors can measure tire temperature compared to the in-tire designs? The Orange system is an in-tire design as is the SmarTire system (since discontinued) on my ST1300. Both seem very accurate.

My wife got me the Rupse TPMS system for christmas. The Rupse uses the sensors on the valve stem. I've only ridden with it a handful of times but so far I've been happy with it. It takes a few minutes for the sensors to connect when I'm riding but once connected they seem to be accurate and as the tires warm up I can see the pressure increase. I've compared the TPMS readings against another digital pressure sensor and they gave the same readings.

Setting the temp subject aside, I've seen one of the cap-mounted sensors broken by a piece of road debris. It resulted in an immediately flat front tire and somebody lucky enough to pull over without falling.
