Nitrogen filled tires?

The price given over the phone was $20 a tire if I heard correctly.


Thanks for the info...

Razor, the price should be $20 for the set of 4 tires.

Cassidy tire charges about $25 in the Chicago area. There is a $5 off coupon in the sports section of the Tribune monthly. Refills and adjustments are free. They only need to "raise" the car on the first visit to properly do the "flush".

FYI- Costco only fills with Nitrogen on new tires purchased there.

I think Costco uses nitrogen as a matter of course. At least I don't remember them asking me if I wanted it on the last set of Michelins I bought there. Subsequently a Honda service rep told me they didn't check the tire pressures because they didn't have nitrogen anyway. Which left me saying wtf to myself since I had rebalanced tire pressures on the car any number of times using the compressor in my garage. Apparently mixing nitrogen and regular air doesn't cause them to explode or anything.

Hi Ronzi, I think the Honda dealership was trying to do you a favor by NOT adding air to your nitrogen fill, and diluting the ratio. Now, if you don't care about the % of nitrogen, just let them know the next time. The green caps are their warning to not fill with regular air.

I'm sure you're right. I asked the Honda rep how the tires would have been filled with nitrogen, and he said I probably got the tires at Costco, etc. I wondered why they put on those green valve caps. Now I know. Thanks.

When I see a vehicle with green valve caps I think Costco since Costco (at least the ones where I live) has been using nitrogen for years. My local dealer has also started using it. I consider it a gimmick on a street vehicle.

My 1988 Toyoya work truck needs new tires. Last set was put on by Costco, but that was years before they started using nitrogen. After the holidays I will have Costco put on another set on the truck.

Then I'm going to take the green caps off the truck and put them on the Boxster.

Then I'll let all the air out in the Costco parking lot and get free nitrogen in the Boxster.

Geez, the reason I thought they filled with Nitrogen was that it was "dry" and therefore provided a more even pressure in relation to the temp. Essentially your tire pressure stays stable as the tires warm up as there is no water to vaporize and expand, thereby provide more predictable handling. As for mixing with air, dont we breath around 80% nitrogen anyways and I havent burst in to flames lately

take a lighter and place it behind ur rear when ure gasy, im sure ull see mad flames
make sure u wear green underwear after that

Hi,

Nitrogen (N² in molecular form) is essentially (but not truly) inert and not easily reactive. It is non-flammable and referred to as a Dry Gas because it doesn't absorb moisture easily (though it does absorb some) as you point out. This means it expands less than a standard Air mixture, and is more consistent not varying with changes in Ambient Humidity.

But, another advantage is that Nitrogen molecules are essentially larger and therefore will diffuse more slowly from a porous material (such as a Tire) than Air would.

Normal Air is mainly Nitrogen and Oxygen (other gasses as well, but in insignificant amounts for this discussion). About 78% Nitrogen and 21% Oxygen. Since the Oxygen Molecule (O²) is essentially smaller in diameter, it can leak easier and since it makes up basically 1 in 5 of the molecules in a given volume of Air, the tire can lose pressure more easily than if it were filled with Nitrogen alone...

bmus,

Can you provide more information regarding Cassidy Tires ?

Where are they located ?

How long did it take ?

Do you need to make an appointment ?

Anyone in particular to ask for ?

Thanks,

Nick

Hey Nick:

Use the "store locator" function here:

http://www.cassidytire.com/

I go to the one in Arlington Heights. It's about 1/2 mile from my home. The guy there, PJ, is a good guy. I made an appointment (in March), so I would not have to wait too long.

In late October, I just went over there for the "winter storage over-fill" to 58-60 PSI. They just extended the hose line out to the parking lot, and I was done in 5 minutes and gave the worker a $20 tip.

bmus,

Thanks for the info ! I’ll give it a shot

I bought my boxster used and I saw a sticker where the oil change stickers are usually located. It was from Costco and apparently there is a 3-month service for the nitrogen-filled tires. Apparently the last guy bought the tires at Costco and they will always fill them and rotate them for free. The only problem is that I dont have the Costco receipt so I will not be able to get them serviced for free.

Anyone have an idea of how I can scheme free rotations and fills without the reciept or original costco card? I do have that originial service sticker still on there.

Hi,

And for those of you who cannot waste enough excess Moulah filling your tires with Nitrogen...

Get your next Bling fix by installing a set of 24-carat Gold Plated Springs from H & R. These will only set you back some $2500, but at least they don't need to be refilled.

H & R sold it's 1st set of these Springs to the owner of a Ferrari F430 in Dubai. They're available for a number of applications from Ferrari, BMW (7-series only), and Porsche, including the Boxster...

I am going to wait for them to come out with platinum!
