Have I missed something? Took the 12R into the local HD shop for a state inspection today. Displayed proudly at the service desk is a sign advertising a nitrogen fill for your tires for ONLY $39.95. | ||
| Lovedabueller |
Yeah thats the next big thing. suppose to make your bike way faster. LOL... psst i know the real reason too. | ||
| Froggy |
Sounds about right, it typically goes for 50 cents a pound. | ||

Wow for $40 I think I'll just check mine often and filler up with good ol fashoned atmospheric air.... How much does helium cost, should make a 400lb bike ride like a 350lb bike, just think of the fuel savings! Oh I think i'm on to something...maybe hydrogen! | ||
| Mortarmanmike120 |
I thought it had more to do with consistent tire temp (and thus pressure) then weight. Either way, pretty stupid use of $40 IMO. | ||
| Froggy |
Helium and Hydrogen are too expensive and it would seep out of the tires. You would need to use a special kind of aluminized tire tube to contain it. | ||
| Froggy |
Right, and making tires last longer and deliver better fuel economy is a waste of money.... | ||
| Guell |
Yes, but is it really worth the 40 dollars? Are you saving in the long run froggy or not? | ||
| Mortarmanmike120 |
How is 32psi any different if its air vs nitrogen. Check your pressure more often. I stand by my assertion. | ||
| Froggy |
I have seen it cheaper from local tire shops. Depending on many factors, you can increase tire life by 30% by switching to nitrogen. Then there is the fuel savings on top of that for having a more consistently inflated tire. If you get 10k miles on a tire normally, you could get an extra 3k miles out of it. Oxygen will permeate through the tire about 5x faster than Nitrogen will, and as result the Nitrogen tire will take longer to break down and dry rot. Also the Nitrogen is less susceptible to temperature changes so you will not need to check and add air so often.
Take your car, fill up the left 2 tires with air, right 2 with Nitrogen. Make them all 32lbs, then go for a drive, preferably a long straight slab of highway and get the tires warm. Pull over, and tell me which tires are still close to 32lbs? | ||
| Tq_freak |
you are correct in the fact that 32psi is 32 psi but are you going to check and adjust your pressure mid-ride or stop on your drive into work to check it. Nitrogen is more stable then regular breathing air and its expansion and contraction is more liner then air. In theory your front tire can change psi faster then your rear because it is unknown what the exact air mixture it. But on the other hand $40 bucks? to steep for me. | ||
| Froggy |
My local shop does them $5 a tire. | ||

Has the dry-rot theory been actually tested? There's more surface area on the outside of a tire then inside and it's still exposed to oxygen (tho not under pressure.) I've never had a motorcycle tire wear out do to dryrot as opposed to normal road wear. Also the Nitrogen is less susceptible to temperature changes so you will not need to check and add air so often. I would hope not at $40 a pop. Poor gas mileage is often attributed to underinflated not overinflated tires. Use air, check your tires more often, you won't be underinflated. You can fill your tires with whatever you want. Not trying to start an argument. Just seems like overpriced snakeoil for a harley street bike in my opinion. Keep the shiney side up. | ||

If you have a pressure regulator...and don't count the tank purchase/lease...it costs MAYBE $1.00 for enough nitrogen to fill a set of bike tires. The components in air that contribute to unstable tire pressures are the oxygen, carbon dioxide and worst of all...water. | ||
| Mortarmanmike120 |
In theory your front tire can change psi faster then your rear because it is unknown what the exact air mixture it. Huh? My hypothesis is that it changes psi faster because it gets warmer faster due to both a different volume of air and action at the contact patch. Not because it has a different air mixture. | ||

I get a 78% nitrogen tire fill at a substantial discount.  I never had a motorcycle tire long enough for it to dry rot. | ||
| Aldaytona |
Nitrogen? I'd rather spend my money on something worthwhile. http://www.youtube.com/watch?v=eq263AYgyYg Even though it was "debunked" by the EXPERTS here on BadWeb.  | ||

Billy Mays on $40.00 nitrogen "but wait" | ||
| Texastechx1 |
nitrogen air rots out tire rubber faster than atmopheric air... the funny thing is... the percentage of people that keep tires long enough for them to rot out because of the air inside is VERY VERY small. and when it comes to the air pressure... checking the air pressure in your tires before you go out and ride is part of owning a motorcycle... always has been, and always will be. | ||
| Sifo |
Wouldn't the air on the outside rot the tires just as fast as the air on the inside? Also I can adjust my pressure at home with a bicycle pump and still get 78% nitrogen. | ||

Dang! Now I have to buy Dyna-Beads. | ||
| Crusty |
I'm going to fill my tires with phlogiston. | ||
| Just_ziptab |
If 32 PSI is the straight air spec,it is the COLD spec and is expected to gain the proper PSI as it warms up..........so if you cold fill your tires with Nitrogen at 32 PSI,you have under inflated your tire right from the get go! We go thru several tanks of nitrogen at work every day. It would take mere pennies to fill a tire. | ||
| Sifo |
Dang! Now I have to buy Dyna-Beads. Rumor has it that nitrogen will keep the Dyna-Beads from working. OK, I just started that rumor.  | ||
| Newbuellertoo |
Aircraft tires are filled with nitrogen. I assume it is to compensate for the various atmospheric pressure cycles they go through. What do you do with your tires when you need to add more pressure for two up riding? | ||
| Teeps |
Over priced for the benefits... But if that's what it takes to make you feel warm and fuzzy, Go For It! I'd rather have a nice steak with the $40 saved by using compressed atmosphere. | ||
| Krassh |
Yeah but it is official Harley Davidson nitrogen. Maybe they chrome it? | ||
| Froggy |
It costs more because you need a certified chome specialist to fit the valve stem cap  Anyway, this thread went nuts since my last post so I will make a brief counterpoint. I got 18k miles on a front Scorpion Sync, and have gotten over 75mpg. Just_zip, with normal air, your tires are at the wrong pressure during part of your ride, which isn't good. It increases wear and reduces fuel economy. You use Nitrogen and set it to the correct higher than cold PSI and then forget about it. Sifo, the other 22% being made of Oxygen and other impurities are what cause the major pressure changes. Another bonus, and a reason they use Nitrogen on plane tires is because its less volatile and less traumatic should something happen and you blow a tire on a landing. Texastech, you got it backwards. Nitrogen does not seep out like air, therefore any rot to the tire would be on the surface on the outside, not on the inside or in the middle. Again, $40 is too much, just like how most services from the dealer tend to cost more than elsewhere. Newbuellertoo, my manual says to use the same pressures with solo and 2 up riding, with the only changes being suspension. This isn't a trailer that you suddenly added 10 tons of dirt into and you might need to compensate for it. | ||

#1 - nitrogen molecules are larger than oxygen molecules, so pure nitrogen has less of a tendency to seep out of the tire. #2 - the nitrogen used to inflate tires is "dry" meaning it does not contain humidity. less moisture in a tire's air(gas) means that the pressure won't fluctuate as much due to temperature differences. At work, we use nothing but nitrogen for airing up Boeing 707 tires, but I would never pay $40 to use it in my bike tires. |
