in after the lock
tim is awesome! hahaha team serious!
i run my air through a purifier first. all you people running dirty air are gonna have poor grip!
for the record, i have nitrogen in my mazda's tires. the caps are green. and it sucks. they feel stiffer than normal but it's not worth it. plus dealer fags filled them too low and if its under 60 degrees my tire monitor beeps at me all day, these nitrogens don't expand like normal air. andi cant just go down to publix and use the free air :'(
