Tire is low .. where to fill in sj ? - 986 Forum - The Community for Porsche Boxster & Cayman Owners

nefarious986,

As you can see from my third post that nitrogen is not worth the time or cost for the little to no benefit you'll receive. Just use free, dry air and take the money you would have spent and buy some beer and invite us over to talk cars.

I believe chosing to use N2 in your tires is no different than any other mod/hack. Some people like it, some don't. Some swear by desnorkling. Some say it is a waste. Some spend big buck on the stickiest tires, other say as long they last and look good, a tire is a tire. You pay your money and you make your choice.

Would I pay for N2 if it was $7.50 a tire, heck no. But I get it for free, so what is it going to hurt and it just may make a difference even if slight.

Do the valves have green caps?

My wife's valve caps on her Goodyear Wranglers are green. My valve caps on my Box are black. (My request)

I think the whole nitrogen thing started because compressed Nitrogen is inherently 'dry'. Compressed air typically has moisture. Continual filling with moist air will cause condensation and the water can cause a mis-balance and rot from the inside.

All gases obey the gas-law and expand with heat.

If you are racing and constantly adjusting tires, a small bottle of nitrogen is cheap and more portable than a 12v compressor. its win-win.

BTW, I was cruising the Harbor Freight website today and noted that they have 40 csf and 20 csf nitrogen systems specifically for filling your tires. Includes the bottle, stand, regulator, hose, and tire inflation attachment. When I was at Harbor Freight later in the day I asked out of curiosity and they said they didn't carry it at the store, so you might have to get it off the website. Just FYI.

If you have to have it, pull your car up to an empty operating bay (obviously don't pull it into the bay) at Costco and just ask one of the techs if you can use the hose... they won't check for a card and they always let me do it myself, takes all of 5 minutes.
