Does anybody have the pros and cons with nitrogen filled tires??

 

always constant tire pressure, therefore better gas mileage, slower tire wear, increased safety.

no cons..

 

On vehicles with TPMS, the benefits are overstated, IMO. Same if you regularly check your tire pressure.

If it's free, by all means go for it. If you're paying for it, only do it if you're lazy

 

if you live in a place where outside temperature fluctuates a lot, like in michigan. It's 30 degrees at night, 65 degrees during the day. It helps to have nitrogen in your tires, otherwise tire pressure fluctuates a lot. And one more thing, it increases tire life, as you always have constant pressure and your tires are not inflating and deflating all the time due to pressure difference that occurs as the tires heat up while driving.

 

I would used nitrogen on a Track car only IMO.

 

I really dont know if you could tell a difference between clean dry compressed air or nitrogen in a street tire, or any tire for that matter.... being 70% nitrogen as it is, I think the expansion rates would be very similar, throw moisture into the mix and then you might change things a little.

 

I think all of the big tire places uses nitrogen now

 

It's the moisture in the normal air that makes the difference, in more ways than one. Moisture is bad for rubber/silica and wheels and TPMS sensors. Also, the smaller size of the water molecule is what leads to air leaking out faster. (I'm not a chemist, and can't explain these things, I just read them from a reliable source). N2 filling stations have better drying systems than air compressors alone.

 

and nitrogen is lighter also

 

I use CO2 from a PowerTank© to air up after running with reduced tire pressures off road; and it works just fine.

 

No cons but the pros are highly overrated!

1) Our air is already 78% nitrogen!

2) Aluminum rims are usually destroyed from hitting a curb or pot hole before they are destroyed from internal oxidation and moisture.

3) The tire tread will wear out faster then the inner rubber deteriorates from the exposure to the oxygen.

4) Unless you race at the track where very small fluctuations in pressure can make a huge difference, the pressure issue is irrelevant. All gases expand and contract with temperature including Nitrogen!
Small leaks around the rim or valve stem over time are more of a concern. Unless you go back to your tire shop every time a tire is a bit low on air or have your own nitrogen cylinder in your garage, when you top up you will be adding some oxygen anyway!

Not worth it unless it is totally free, just my opinion.

 

That works out to less than an ounce in total for most vehicles!

 

Agreed.

 

Pros: Potentially dried, filtered air in your tires.

Cons: Only your wallet will be lighter; no cigarrette offered after you've been taken advantage of.

 

im not sure if this persists for tires, but if i remember correctly, the water molecules can go through the rubber or affect the inner surface if they are smaller because rubber is a selective membrane? something like that?

I wouldnt fill up with nitrogen if i had to pay.
