Hi,

Is there way to enable the beeping sound when the car is in reverse, or is this feature not available on 2017 CRV EX. And does anyone know the benefits or putting Nitrogen on the tires. Does it improve mileage ?

There is no benefit to replacing regular air in the tires with Nitrogen on an automobile.

I'm sure you can add an external transducer to your vehicle, that will be audible to pedestrians walking behind you while you are backing up. As far as I know, none are available from the factory.

By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases...

Why pay for an extra 21.91% of nitrogen?

Nitrogen was used on the Space Shuttles tires as they were in an environment of -450F for extended periods and inflated to 400 PSI.

If you are thinking of driving (backing?) your CRV into low earth orbit splurge for the nitrogen...other wise tell your tire shop that you just want 78% nitrogen.

We run nitrogen in our CRV and it stabilizes the psi nicely.
Previously in our summers and winters non nitrogen would flux.

to get the warranty you'd have to have honda install it.

but if you're inclined its not horrible

The only real benefit to going full nitrogen is less oxidation of the tire inside, and it is a dry gas. Since most tires are replaced within a few years, even this is not of notable benefit in terms of oxidation. Water moisture in the air varies by location and weather at the moment, so results vary.

The advantage of nitrogen may be more notable in very humid climates because nitrogen is a dry gas whereas plain air has Hygroscopic properties to it. In such environments, compressed air drawn from the local environment will include moisture as well.. and that will tend to "appear" to bleed off the tire more rapidly then the oxygen and nitrogen... and hence PSI will drop. That is actually water moisture condensing in cold conditions that causes pressure drop. But in reality most tires leak very very slowly anyway as the rubber has some level of porosity to it. The molecular weight of Oxygen and Nitrogen are nearly identical so it's not like comparing nitrogen to helium (which with it's very small molecular weight can and will find pathways to leak away much much faster under all but the most stringent conditions). The absence of moisture is what you are seeing with your summers vs winters with nitrogen as there is little or no moisture in the tire.

Nitrogen can provide modest benefit in conditions where there are extremes in temperature range on the tires.. such as is the case in performance racing. But again.. this is the absence of water moisture, as oxygen and nitrogen have roughly the same coefficient of expansion per degrees F/C. For normal tires in normal consumer driving though, it would be unusual for the tires to reach temperatures where nitrogen is of clear benefit. The actual brand and design of the tire and the wheel you put it on has a much more noticeable impact on stability of tire pressures.

No harm in putting nitrogen in the tires of course.. so ... your tires, your choice. :) The downside is as nitrogen does slowly leak away over time, or weather changes, you cannot readily replace it unless you go to a location with a nitrogen service for tires... so you just end up topping it back up with regular air in most cases anyway. Personally, I lower and reload the air pressure on my tires during warm summer time (low humidity) and it seems to work as well as purging with nitrogen for me as it provides essentially the same stability in PSI. And through the rest of the year, when I need to add a pound or two of pressure.. it does not inject much water moisture, even in winter, in terms of total air volume in the tire. Of course I have to wait until middle of summer for this... but I also don't have to go to a local tire shop that has nitrogen either. :)

Nitrogen in auto applications is a waste of money. It is used in aircraft for two treasons. One, it is a bit more stable with the extreme loads put on aircraft tires when on the ground causing massive heat build up. Two, nitrogen is inert. If a tire explodes in a wheel well while airborne, there is much less of a chance of a fire. By the way, fire is not good.:confused2:

How do you get an additional 20% of nitrogen in a tire?......pull a vacuum and collapse the tire on the rim?......I don’t think so. Nitrogen filled car tires is +/-$300 ADP.......additional dealer profit.

Nitrogen in tires is the modern day version of the snake oil salesman.
I agree with this, BUT...why does Costco, a company I respect, fill all the tires sold at their tire centers with it? At no additional cost. :Dunno:

Because it's cheap marketing, and tires are expensive with a high markup. Nitrogen is the cheapest industrial gas available; I'm too lazy to do the math, but even without a wholesale account, the very-largest tank of the stuff (enough for a large number of tires) goes for $65.

To make it look like you're getting a benefit for being a member.
Yeah, I suppose, Costco offering it free makes it look like a membership benefit, and a possible draw to tire buyers.

I was basically responding to the snake oil comment, and, as we all know...snake oil refers to a product that doesn't do what the "sales person" claims, other than make that said sales person extra money, potentially leaving the buyer without a proper solution to their problem. Snake oil refers to an elixir that was promised to fix what ails.

Anyway, I've been a Costco member for a long time, yet I can't remember the last time I bought tires there.

OH! That's right, I haven't kept a car long enough to need tires. Just kidding! Actually, I put new Michelins on my wife's '15 Escape in Jan 2018. Bought them at Discount Tire.

There may be some benefit to having Nitrogen in your tires, but not likely worth paying a new car dealer anything for it.

I got nitrogen at my last tire purchase with the promise they would maintain their pressure regardless of temp. They elevated 4 psi when warm just like "air".
It has a small benefit, but not worth paying for.

"For tires, this means every ten-degree change in ambient temperature will result in approximately 1 psi change in tire-inflation pressure. This change is the same for nitrogen-inflated tires and tires inflated with air."

Yeah.. I quit buying tires at Costco years ago. Americas Tire provides better service, a wide range of tire choices, free repairs, free rotations, optional warranty extensions that include road hazards, and their prices are as good or better then Costco. Plus they take appointments and they actually keep them. Costco now does appointments, but it's a complete zoo from what I hear and they always run late, at least where I live.

Americas Tire does not do the nitrogen thing... and I am fine with that.

Agree. Discount Tire is the same as America's Tire, just depends where you are located. And they will rotate tires, and do repairs for free, even if you didn't buy them there.

They will also beat any price for the same tire...even Tire Rack.

Great company.

Reverse beepers are easy to install. Most of them just tie into the reverse lights for power.
Just search Amazon for (reverse beeper for cars) and you will see a ton of them listed.
