Nitrogen vs Air in Tire

[turbocharger 71]

no problem with nitrogen air have been using it for the last 5 years mga P50 per tire lang then pwede naman ordinary air for maintenance so far wala naman effect sa tire and sa ride parehas lang

[wewoy_romero]

never had a problem using ordinary air for my tires. less complicated. less hassle.

I used Nitrogen for one reason: air pressure doesn't drop down as fast. (i only need to air up every 3 months or so), and i air up it a place that is convenient (S&R).

I air up in an even more convenient place.

My garage.

Pumping four tires to 55 psi by foot is good exercise.

Free refills right?

55?

Sa garage lang din ako mag refill. I use automatic digital tire inflator. With normal air, you lose 1psi per month. Adding air once a month is not difficult to do.

Have you seen how they put nitrogen into your tire?
The last time I have our wheels replaced, there is a free nitrogen fill using a quite big (as in refrigerator size) machine.

However, the tires were not evacuated of ordinary air. So I am not actually sure if it'll work knowing it is not pure N in your tires.

Not with regard to expansion of gases/change in tire pressure as temperature changes, I dont think we have that much of temperature fluctuation in our country compared to what other countries or car racers' tires experience to really benefit from Nitrogen.

More to the point, since oxygen permeates through rubber more readily than nitrogen, eventually your 80% nitrogen fill (normal air) will reach about 90%, as long as you keep re-inflating it (at high pressure) with regular air.

As the percentage of nitrogen increases, the air loss per week slows down.

I now only have to check my tires once every other week. They stay consistently over 45 psi (when inflated to 50).

55?

55 in front, 50 in the back. Feels much better than standard pressure. I'm using cheap Turanzas with tall sidewalls, and at lower pressures, I don't like the handling. With old 80's and 90's performance tires, you sometimes had to fill to 50 for best track performance, though modern stiff-sidewalled tires do well in the 35-40 psi range.

60 is about the limit of what my dual-cylinder foot pump can do, though it's rated for 100 psi (yeah right, if you have the legs of a horse, maybe).

Ah you're still running airliner-level tire pressures I see

OT: When I was in grade school I was the official hand pump operator. It was my dad's way of introducing me to the joys of car ownership and maintenance

Aren't airliners at 100 psi?

Could be worse. Some police instructors swear by 60+++ psi. But if you see the kind of hard-wearing balloons they stick on police cruisers... which often weigh nearly two tons, thanks to the equipment on them... you'll understand why they do that.

I know I've posted this before, but it's an interesting watch for people who think that tires will automatically explode the moment you go past 40 psi.
