Funny, I've been looking at the insides of tires for 30 years, and while the outer rubber may be severely weather-checked (usually described as "dry-rotted") I've yet to see an example of 'oxidized' rubber on the inside.More importantly for those that do not drive much (such as me) is the fact that Nitrogen does not react or oxidize the rubber inside the tire. So the rubber last longer inside while the outside degrades the same as usual.
Honda Tech,Radar, how does a post about Nitrogen filled tires turn into a rant about TPMS systems and Air Bags? The OP wants to know if the Nitrogen fill in his passenger tires has merit, or if it's just another form of snake oil. Honda's position (in print in the Service News) is that it is unnecessary and a waste of customer's money. Personally, I have very seldom checked air pressures on a "Nitrogen Filled" vehicle and not found lower pressures than specified. They get topped off with regular old air.
An constant tire pressures would not benefit our CR-Vs? Allowing more fine tuning of the suspensions? Too bad Honda has not taken to Nitrogen.Nitrogen is only practical in racing conditions, mainly to hold more consistent tire pressures thru the temperature range.
There is no MPG benefit at all. In fact, you could be getting LESS MPG. How? Because with Nitrogen your tire pressure won’t rise as it would with “air”, when the tire warms up while driving, and levels out (about 2-3psi) above the PSI you set when the tire was "cold".
And this is where IMO, the “better ride” people get their feel. Its due to the tire not getting as hard from the rise in pressure going from “cold” to normal driving conditions.
Fine tune suspension on a CR-V? Riiight...An constant tire pressures would not benefit our CR-Vs? Allowing more fine tuning of the suspensions? Too bad Honda has not taken to Nitrogen.
On your second idea of getting less MPG I would have to give that a flimsy thumbs down. Low tire pressures reduces MPG much more so than high tire pressures increases MPG was the opinion taken by an authority. I forget the rational but it made sense at the time. Yes I know some swear by 60 PSI... What can I say.
On the ride quality aspect it is very subjective but after getting new tires at Costco (who uses Nitrogen) the vehicle seems to ride way better even after replacing with the same identical tire manufacturer, model and size. Like I said it is very subjective but that was my opinion without even knowing about the Nitrogen. For the longest time I could not figure out why.
On fine tuning, whatever. If you mean it cannot be improved...then it can't? Wouldn't a more constant tire pressure allow better selection and design of springs etc? It might be more touchy out of that pressure range...Fine tune suspension on a CR-V? Riiight...
For every PSI up or down = the same % of gain or loss of rolling resistance.
Of course new tires will ride better than old. Nitrogen had no impact, sorry.
$60 for Nitrogen? Did they have a mask on while negotiating?I didn't have a choice....it was a $60 "dealer installed option" when I took delivery of the vehicle. GRRRRR! I feel violated.
I'm surprised Honda puts out something in writing about add-ons that are a waste of money. You should have seen the list of junk my dealer was trying to sell me after we closed the deal.
