New portable compressor worked the charm to bring tires up to 32 from a drop to 28.
fine with that tho have managed to misplace the little USB charging cable that came with the TPMS
Your post reminded me to look into a motorcycle TPMS. Found this on Amazon, and for $31 with Prime return policy, hard to resist:
YUPVM 2PCS 5.0 Motorcycle TPMS Tire Pressure Alarm System Sensor Android/iOS Tyre Pressure Monitoring System 8.0 Bar, Black (500133953) in Tire Pressure Monitoring System (TPMS).
www.amazon.ca
Setup was pretty simple, just download the app on your phone, screw in the sensors in place of the caps, then pair them. The app is pretty basic, just one min and one max pressure alert to cover both sensors, but it works. All I really wanted it for was to check pressures before taking off, but now that I have it I can also be alerted to a low pressure scenario while riding. I'm going to keep trying other apps to see if I can get one to work that has more features such as separate alarm thresholds for front and rear.
Since these depress the Shrader valve and cause air loss while installing until fully bottomed out, I found I had to over-pressurize the tires, install the sensors, check pressure in the app, then if necessary loosen and retighten the sensors to release additional pressure as necessary until you get it down to where you want it.
My first impression is that it's pretty cool for $30. The downside is that the sensors need to be removed to add pressure, which can be a hassle if you use the locking nuts to prevent opportunistic thieves from just unscrewing them. I'll have to see how it is to live with over the next week or so, as I check my pressures daily on the supermoto because of the low pressures I run on the street (26/29), so there isn't much room for error.
