Have it in my 08 SG, Harley put it in both tires when they were changed. The Ultra came withit in the tires when I bought it.

 

Those came with the Dolphine whistle, the earlier ones came with a decoder ring. Keds sneakers were PF Flyers competitor.

After we got into our teenage years it was Pro Keds or Converse All Star sneakers for many of us. Those were the days of $10-$15 sneakers. Today ghetto-fashion means $400 plus sneakers.

 

As has been said before, I use the hybrid Nitrogen blend, which is 78% nitrogen.

Ride safe!

 

no - read it was a waste of $$ -

 

I have not had to put more nitrogen in ...in about 6 months. I think it's good. The bike seems to always feel like a new tire is on.

 

Aaaaaaaaaaaah PF fliers.... I can hear you coming down the court flop flop flop lol.

 

Thought I'd try it out when I last had my tires changed on the SB... that was about 14 months ago,tyre pressures have'nt dropped,more even wear..equals more miles before I have to buy new..I'd do it again.

 

I did nitrogen in the tires of my Corvette which sits in the garage for about 350 days of the year. Not one time in the past 2 years have I had to add air, the pressures stay the same.

 

Nitrogen is for *******. I use Helium 'cause it makes the bike lighter and it also goes way faster up hill.

Actually, I hate to burst you bubbles but Nitrogen in street tires is a complete and total waste of money. The reason it is used in racing is that Nitrogen (usually called Dry Nitrogen), has little or no water moisture in it. As a result the tire presssures change much less as the tires heat and cool. Since the difference in 1 or 2 PSI can make a world of difference in how it works on the track it's much easier to "tune" things when Dry Nitrogen is used as opposed to atmospheric Air . . . which is already 72% Nitrogen. On the street? Geez, just set your pressures when the tires are warm (after a few miles of riding) and then check to see what they are when they cool down. Now you'll have your Hot and Cold tire pressures . . . write them down somewhere . . . you're good to go . . . sans Nitrogen and whatever the local tire shop charged you for it.
