What are you using in your tires: air vs nitrogen
Good evening!

Thank you for all previous write ups about Nitrogen vs Air in the tires. It seems that the conclusion is "if you can get it cheap, use it, otherwise it does not matter unless you are racing"
I would like to open a poll to see what M5 owners are using

I got my car recently (green caps). The tires are slowly deflating and I am trying to decide if I should find a local nitrogen refill station or just use a regular gas station. I could use a regular tire inflator, but Boston air is quite humid...

from what I understand, the benefits of nitrogen in street tires is negigible - especially if the tire shop you're bringing it to is unable to create a vacuum in the tire first to evacuate existing air before filling with nitrogen

First post conclusion is incorrect..."racing" has nothing to do with it...

The 'nitrogen fill' you get at tire stores is NO BETTER than 94%... Unless you are using bottled, technical pure certified moisture free nitrogen, you will not see any of the MARGINAL benefits, The n2 membrane concentrator has a 94% upper limit

Biggest single issue? Moisture. Use air, with a drier on the line and you're fine. For track use, many have a n2 bottle for topping off shocks, so adding a lower press reg makes sense..

.I see green valve stems and laugh, especially on a minivan!
