If you pay extra for Nitrogen then you're an idiot. It does NOT add 40% life.
I've been running all weather Michelin Pilot Sport A/S Plus and have found them to be a far better tire than OEM.

Only those of us who live in hot temperate hazardous climates will get the 40%. We also have to purge any air out at filling. Not for cold all seasons like you live in.
Air and Nitrogen CANNOT be Mixed!
When tires are inflated with air, over time the pressurized air inside a tire, will slowly escape.
On average, tires compressed air will lose 2.7 pounds of pressure monthly, compared to nitrogen tire loosing 0.7 pounds. The air inside tires expands, when exposed to heat and contracts when cooled. Tires loose more air when exposed to hot weather, compared tires filled with nitrogen, remains twenty percent cooler. Scientifically, nitrogen molecules are bigger than air molecules, thus nitrogen escapes a tire more slowly. According to Ingersol-Rand Company, makes nitrogen inflation systems, nitrogen leaks out of tires about 30 to 40 percent slower, compared to air filled tires. Compressed air contains moisture and oxygen, which can cause oxidation, corrosion, leakage, and accelerated wear in tires. Tires containing nitrogen do not cause any these corrosive problems.
Problems associated having low air pressure in tires, when air escapes. Decreased air pressure on a tire, causes more of the surface of the tire to be exposed to the road, which reduces tread on a tire. Eventually, if the driver is unaware or does not periodically check the tread on a tire, will cause blowout on the road and may lead to a serious car accident. Also, the friction of low tire pressure makes a car engine work harder. Basic rule to follow, when tires operate below twenty percent of optimum safety, will reduce the tire life by up to 50 percent, and tire rolling resistance can add ten percent or more to fuel consumption. Regardless whether air or nitrogen used to inflate tires, tire pressure should be checked once a month and tires rotated every 5,000 miles.
Nitrogen filled tires will not fluctuate as much or be susceptible,
by temperature changes. Tires filled with nitrogen will cause treads on tires to degrade much slower, ride longer, and cost less replacing tires, not as often. When fewer tires need to be replaced, this contributes to helping the environment by minimizing the number of tires for waste disposal and less number of tires, being manufactured, which conserve natural resources. Also, less number of times, need to retread tires, will conserve millions of gallons of oil every day.
The Earth's atmosphere contains about 78 percent nitrogen, which is a colorless, odorless, and tasteless gas. Approximately $10 to fill a tire with nitrogen, over the long term saves money driving longer on a tire, saving money at the gas station having properly inflated tires, and priceless lives saved, driving a safer vehicle. Michelin tire officials recommend nitrogen only for tire used "in a high - risk environment and / or when the user wants to reduce the consequences of a potential abnormal overheating of the tire-wheel assembly," according to company statement. The availability of nitrogen on highway transportation is slowly getting recognized and more manufacturers have entered the marketplace.
Tire efficiency becomes less effective, when nitrogen and air are combined together. A driver may have to refill the vehicle tires with air, when nitrogen is unavailable for purchase. Recommend by manufacturers of nitrogen inflation system, existing nitrogen and air in a tire should be purged, before the proper amount of nitrogen can be added, as soon as possible. Also, drivers will notice if one of the front tires contains both nitrogen and air, will encounter some steering problems, whereby the vehicle may pull to one side, while driving. However, if both front tires are filled with equal amounts of nitrogen and air, shouldn't be any steering problems. Green valve caps are used for nitrogen - filled tires, to distinguish them from oxygen - filled tires.
Available various types of nitrogen tire compressors. Jay Lighter owner of F Tire & Auto Repair in Pompano Beach Florida owns NitroFill, a system for generating and inflating tires with nitrogen. He invested approximately $1 million into development of this system. In 2005, he bought the NitroFill brand from Pneumatech Incorporated, Wisconsin firm. Since May 2006, he sold his equipment to about 100 tire and auto dealers around the nation. Also, NitroFill has a patent pending on the Inflator (name), used to take oxygen out and, put nitrogen into tires. In September 2005, Sunrise Florida Company N2Revolution's, at corporate headquarters (Owner Robin Pearl), launched it's inflation solution PurigeN98 nitrogen (98 percent pure) compressor. Also, Ingersoll Rand is leader in the industry, selling nitrogen compressors for tires. In November 2005, N2Revolution signed an agreement with Crown Auto Dealerships Incorporated, providing nitrogen inflation systems PurigeN98. Nitrogen filled tires will be the standard feature in new cars at their dealerships. The PurigeN98 is being used to inflate tires on vans, cars, recreational, and other vehicles. Also, likely inflate tires on bikes, ATV's, and other types of vehicles using rubber tires. N2Revolution has a patent pending Nitroflator, which generates and dispenses Purigen98, through fully automatic electrical controls and monitoring systems, temperature controlled air supply and a space-saving cylindrical design with blue colors. Additionally has an upgradeable capacity. N2Revolution guarantees the highest level of pure nitrogen (98 percent).
Nitrogen molecules are larger than regular air molecules, so tires deflate more slowly.
Nearly 5% of brand new tires come rom the factory with a manufacturing defect that makes
them nearly impossible to balance using any system. Nitrogen Tire Fill and Ride-On TPS Tire Sealant:

So,...If tires are hermetically sealed (valve stems included) they may not leak at all.
I recommend you train yourself to constantly maintain your tire pressure as a Habit!
