Tire pressure extenders and TPMS

Overall, IMHO, you'd be better off getting some solid dually valve stems that are long enough to reach through the wheels. Best money I've spent so far on tires. No pressure losses in the past 2 years since I installed them! The braided extensions always leaked, no matter how I tightened them or how new they were. I never tried the solid extensions, but there are fail points at every place they screw on to the actual valve. I still check pressures before each flight, and I have not had to add air since getting the solid valve stems. I suspect the TPMS will work better on the solid stems too. I haven't re-installed my TST yet, but will do so this season.
