Yes, had it put in when replaced both fron & rear tires. I couldn't tell a difference. Does not leak AS FAST as good old faishoned "air," but it does still require occassional top-off. Still check pressure every time I ride and have had to top it off with air. Would not pay for it, seems like another way to grab $$ out of the pocket....

 

I have one of those compressor filters too...Works good...once a week too.

 

heres my custom blend.

Don't forget to fill up with Nitrogen Enriched Gasoline (Shell). It's supposed to seek and destroy engine “gunk”.
What a bunch of BS!

 

Yes. Dealer had an offer of free evacuation of air from the tires and replacement with Nitrogen at a major service. Cost would have been $22.

Had 10,700 mi on tires with air in them. Altitude range -260' to +8400', temperature range 40F to 110F.
Have 2,500 mi on tires with Nitrogen on them. Altitude range +600' to +9200', temperature range 60F to 110F.

Speeds from city driving to sustained 80mph.

08 RKC with tubed tires on laced wheels.

No apparent or evident difference.

 

And how exactly do they evacuate the air? Maybe they mount the tires under vacuum.

 

You don't think they can evacuate the air from an inner-tube? Or do you have a problem reading for comprehension?
