idk but ive gotten over 22k on my stock tires with a TON of hard driving. i am just now getting to the wear bars on the rear and fronts look brand new!

 

This is an interesting figure. 22K with hard driving is getting twice the life from the tires. I just hope this is not some anomaly.I mean no disrespect to you but I actually read a guys post in which he went 68K or something on his original S02's.

 

haha 68k?!? no im already planning to replace my rears soon. but they still have a decent amount of life left. yesteday i was driving through a monsoon and the car never once squirmed or hydroplaned even going through decent size puddles and ruts in the road!

the front shows slight camber wear but other than that it looks new. no lies here! im surprised myself!

oh btw nvr once have had to put air(nitro) in the tires since purchase.

 

If someone posted that, I would immediatly say BS to that claim.

When I had SO2's I drove VERY nicely and only managed about 22k miles on the tires when the average is about ~15k.

 

you can feel it. my stock sets of tires were filled with nitrogen and i've been riding on them aggressively for 2 years and have never had to refill them. i have about 10-15% tread left on all four. the nitrogen outlasted the tires.

i recently bought some aftermarket rims with tires. these tires were filled with air. after about 6 months of use, i'm down to 25% tread and i dropped about 16psi in air. (yes i measured the psi when i had them and measured them when i took them off)

i recent put my stocks back on after about 6 months of storage, and everything is good plus my mpg increased. NITROGEN FTW

 

hmmm thanks for the fast replies....i guess ill leave them with N2 then...

also i wouldnt know the difference because ive never driven a s2k with reg air :\ hopefully the N2 is doing its job

 

Air is 78 percent nitrogen, 21 percent oxygen, and 1 percent other gases by volume.

The reason 100% nitrogen is used is simple. It expands and contracts less than air when heated and cooled. It also diffuses out of the tire *slightly* slower than O2 does. It has no other benefits.

This leads to more consistent air pressure in the tire under track conditions. For a road car, that's pretty much worthless, as I doubt you'd care much if the tire is at 32 psi one day and 30 psi the next.

My father and I ran nitrogen-filled tires on our 323i back in the early 80's, and it made a big difference in that it removed a fairly otherwise-large variable when attempting to set up the car.

The main reason nitrogen is used is for aerospace safety. An air-filled tire can explode if superheated, whereas a nitrogen-filled one won't. The crash of Mexicana Airlines flight 940 in 1986 graphically illustrated this point.

 

We have the filtering system at my work and i have tried it in all my cars and have seen no real noticeable diference..... The only things it will do is make your tire pressure more stable ( stay close to the same pressure hot and cold ) and it will slow corrosion build up on chrome and aluminum wheels.

The filltration system removes / separates Nitrogen from all other materials found in compressed shop air....... This Will NOT make your car faster.......

Anyone firmiliar with the periodic table of elements will see that Nitrogen ( 7 ) is higher than Oxygen ( 8 )...... Nitrogen has a smaller Atomic mass than Oxygen which makes each particle smaller and the ability to escape from the tire is increased

 

Be careful the right mixture of oxygen and nitrogen can be VERY FLAMMABLE. I believe the percentages are like 100% 02 and 0%N

 

I everytime I read one of these "nitrogen in tires is better because..." threads.
