Your pushing the N2 program appears to be driven by advertising dollars. This whole thing is a sham propagated by equipment manufacturers.
In our neck of the woods, N2 is already being given away for free with a tire purchase. We use the Consumer Reports article to show that N2 is not the value that should make your tires more expensive. (What is better, air or dry air?)
I’m afraid that the day of the tire purchase add-ons has come and gone. Now most of us are just happy to get the sale and hope for some car repair add-on!
I have been reading your magazine for most of my career (38 years) and continue to enjoy most of it. Thanks.
