Tire pressure monitor quit.

[exavid]

I took the scooter out this morning and discovered that the tire pressure monitor was only showing dashes. It didn't matter how fast I rode the bike either. After scratching my head about it this evening I disconnected the battery for a few minutes in hopes that resetting the ECU would cure the problem and it did. After thinking about it I realized I must have confused the bike when I disconnected the battery a few days ago when installing another power socket. So if you have an oddity like that try resetting the ECU.

Was there air in the tires? 😄😜. Kidding...

Hey, I cherish the tire pressure monitor. Sure beats dragging these old bones down to the floor for the daily tire pressure check. Not so hard to inspect the tires but a real bit of bother when you do it with arthritis. I used to use air in my bike tires until I started using 78% Nitrogen for filling them. The really run well with that in the tires. Highly recommended.

You do realize that "air" is already 78% nitrogen, 20% oxygen and 2% other gasses, right?

Even if the dealer when you bought said we put nitrogen in the tires. In the spring you take the scooter out and the tires are low on pressure. You put the compressor on and add air, you now have air in your tires. This would also happen if you play with air pressure for riding style or weather.

I do not understand why people think 100% dry Nitrogen is any better than compressed air. One plus to this, Nitrogen will not escape through the sidewalls quite as fast as compressed air.
Nitrogen is and has been for years in the aviation business required in aircraft tires. Reason is to eliminate wheel well fires in the case of a half flat tire exploding filled with compressed air and causing a fire in the confined space of a wheel well. To use Nitrogen in an open area as our tires run or cars or trucks is nothing more than a waste of money.
Next time your tire guy try's to sell you a $35.00 Nitrogen fill, tell him to kiss off.

That is an interesting bit of minutia. Good to know. I will definitely have to figure out a way to work that into a conversation today.

THANK YOU, Dale. I've gotten into more arguments with people who STUPIDLY threw away their money on inflating their tires with dry nitrogen. I've had friends in the aviation industry tell me it made NO sense outside of aircraft use, but you're the first person to explain WHY.

I've even seen these charlatans popping up at motorcycle rallies over the past couple of years and people paying good money for that snake oil too. PT Barnum had it right when he said "A fool and his money are soon parted."

Getting back to the tire monitor question. Once a week or before a long ride I check the pressure with a digital pressure indicator. The monitor is OK but it is compensated pressure and not actual pressure. I am old, I want to know exactly what I have in the tire, I question everything.

Back to dry Nitrogen. A normal wheel on a commercial aircraft at takeoff is 200F at 160 or 180 MPH, say it is half flat, pull that tire wheel assembly into the well, it is 400F to 600F the over temp plugs have popped out and now bang the tire explodes if you were to feed it with 20% oxygen you have a fire now we know nitrogen will not explode or burn and no fire.

For us a bike tire would never reach a temperature or pressure that would make it fail without the handling or smell being noted so why would we need nitrogen.
