I was at the dealer for a minor repair (broken rear spring, and broken pass side window motor)

The service advisor was doing a HARD sell to a customer in front of me on filling her tires with nitrogen. Apparently she needed tires very soon.

The dealer must have got a machine and wants to pay it off immediately or something! I did not catch the price they were charging (it was not free). Telling her she will get better mileage, better tire life, everything short of curing cancer!

I agree nitrogen is better, but he was waaaay pushing the truth!

As she walked out, I told her - Costco uses nitrogen - for free - and their tire prices can't be beat!

I have heard stories from people being (stronly) sold on nitrogren for $5-10/tire. Just never saw it being done. Very strong sales pitch. Almost as strong as the pitches to give them perfect ratings on the customer satisfaction survey!

I was just blown away from the strong sales pitch he was giving.. was unreal.

I did not get the pitch though, he must have seen the green valvestem caps on my wheels

But I don't get it. It matters most on a track. But with the temp swings I see, I'm still going to be adjusting my pressures, even if not as much.

BFD.

We don't have a costco here, and if we did I wouldn't trust them with my TT.

I use Helium to reduce unsprung weight.

rims. Then you can be cool like Ferrari. But yeah, any gas mixure should be fine if you pull the moisture out of it. I wouldn't use pure oxygen, but only because of the fire hazard.
