back tire air pressure

get nitrogen

it's free and it's everywhere! says Jay! whee! seriously if you don't have 600 mi on your bike in 3 mos, you're not driving it enough! :banghead:But thanks everyone for this wealth of information! :clap:you guys are the font of knowledge of all things! and Happy New Year! :yes:

I agree...

You are right, I know of folks who had 600 miles in one month but we all go at our own pace. Plus I didn't get my M endorsement til close to the end of November(before Thanksgiving though). I think the big difference between me and many other spyder riders is that the spyder is a secondary, mainly for fun, vehicle so with my wife and now with my daughter I have to always take my truck or our SUV if she/ they are with me which is more often than not. That's why I go by Laila's dad. If I was on my on schedule I would have went with "sergeant G" or something I thought was cool, lol. :roflblack:

We put Nitrogen in tires for customers if they ask/demand. Yes, to me it's a gimmick.. We have this special air gun with a filtering system and it inflates the tire. ''Direction for use'' Remove valve core, allow tire to fully deflate, Place chuck on valve stem inflate tire to proper pressure, release air and start the process over, repeat these steps 3 times, on the final step insert valve core and inflate tire until proper pressure is desired. Place the supplied valve cap with "N" on it.

I understand the therory behind this process, but don't put alot of faith in the gimmick. No where do I find instructions on wringing out the filter. Or how many fills you get with said filtering system :read: I don't push the product but will oblige the consumer when they demand "Nitrogen Fill".. That'll be $25.00 and have a nice day!

Thanks for some truth from the other side of the airhose! :2thumbs:

In a racing tire, where 1/4 pound can make a difference, it can be somewhat helpful to run nitrogen. Remember that races only last a short while, and the only variation they are chasing is due to tire heating, rather than a wide range of climatic changes. Using 100% nitrogen makes things a bit more predictable...and nitrogen from tanks is dry, to add another constant. For street driving the use of 100% nitrogen is of minimal value, there are too many other variables. It is strictly a money maker, and any benefits are more perceived than actually realized.

I agree that the nitrogen is a Joke in passenger cars. First of all, anyone who has worked in the Refrigeration Industry knows that nitrogen is very cheap and every AC&R supply has cyclinders of it. It is used to help purge non-condensibles (air and moisture) from closed systems before hooking up the vacuum pump. The new car dealers use it as a con to get extra money on the window sticker. Period. I do a lot of driving in my job and go through a new car every two to three years and the last two I've had did have nitrogen in the tires. I told the dealers that I wouldn't pay the $199.00 extra for it that it is a joke. My experience with it is it is true that nitrogen does maintain a more constant pressure than air but only by a fraction. My present car has the tire pressure moniters on each tire and the pressure will fluctuate by at least two pounds. Why? My guess is the tire compound will expand or contract with temperature thus the nitrogen has more or less room resulting in a pressure change. I can understand maybe one bad moniter but all four tires stay within a half a pound ranging from 36 to 38.5 from cold to warm. This is something I have kept track of for thousands of miles. Whenever I have had to add pressure due to a flat or normal leakage I add air,. not nitrogen.

Didn't mean to get long winded on this but I hate to see people get "ripped off" at the dealers.

Nitrogen in tire/wheel assemblys with aluminum (aluminium for you Brits) wheels ,apparently, does not corrode the wheel like regular air. So ...... If one is planing on keeping the wheels for a long time and not wanting to keep topping up with air, nitrogen is apparently a good choice.

In over 50 years of running alloy wheels and using air, I have never had any wheel corrosion on the inside...even with magnesium wheels. If there is any advantage to using nitorgen at all, it would be because it is dryer when taken from a cylinder. Maybe we need to call Mythbusters on the nitrogen topic.

Nitrogen will damage wheels, But only if you use the liquid form.
Makes them brittle. hyea:

Conclusion

Realized, I never stated what I found out about why my back tire was loosing pressure. I had a defective tire with a knot on the side wall. Very grateful that it didn't blow while I was rolling.

And look at..!!

The wealth of information you got for asking. One has to be cautious here when asking or they will drown in responses. Glad you found out and before anything serious happened...:2thumbs:
