I know that many tire shops add Nitrogen instead of air in the tires. I don't think my new CT has Nitrogen in the tires. Should I opt to change the air in my tires? Will it benefit me in anyway? Better fuel mileage? Tires last longer?
A36 hot roll steel is 96% iron. . .T316 stainless steel is 65% iron and it costs 4 times as much, so there's a lot in the percentages.My dealer charges quite a bit to change the factory air to Nitrogen. Since air is 78% Nitrogen to begin with I opted out of it. Now some tire places (Costco) only fill their new tires with Nitrogen and put the little green caps on the valve stem. Air sems to be OK for me.
Seems most dealers miss the most obvious place to use nitrogen because of pressure consistency. . .
Yes you're, theoretically, supposed to check your spare when you check your other tires, it's recommended level is in the door jamb (60psi).Seems most dealers miss the most obvious place to use nitrogen because of pressure consistency, the not-so-easy to access spare.
Yes that's correct:Don't believe the spare has a sensor for TPMS. When I took delivery of my CT in 5/11 the dealer had filled the 4 road tires to the max pressure on the sidewall, not a good idea. I try to check my tire pressures monthly but don't always feel like dropping the spare. I keep meaning to purchase an "Accu-gage - Chek A Spare, Valve Extender" to make the task easier.
Nitrogen, Nitrogen!I've been considering using oxygen, but it feels like an unnecessary expense. Just keep your tires full, and you'll be fine.
True, but if you can get it for free and its convenient, why not. I probably wouldn't pay for it from a gas station. I wouldn't be surprised though if more and more start to carry it for free as time goes on (having just filled up at $4.55 @ gal for 87). I don't have it in either of my vehicles at this moment, but next time I swing by Costco I might have them switch it out.Aceman, you are probably right but in the scheme of things you would do just as well by checking your tires regularly with regular air and save the expense of nitrogen. My Honda can easily pull 27 to 28 MPG over the road at legal speeds with synthetic Mobil 1 0W-20 in the engine and Mobil 1 synthetic gear lube in the front differential. 2010 Crosstour EX-L 4WD
