    Are the 2018 tires filled with nitrogen? If yes is there a product out there to top off air?

    Not sure, any reason to stick to nitrogen? Sure it isn’t susceptible to temperature changes but I think the benefits to it are very minimal.

    Does it have the green valve stem caps? Also, if they are nitrogen filled, from what I’ve read there isn’t anything wrong with topping off with compressed air.

    I wouldn't think so, my 2019 was not. As said above, they should have green valve caps if so. I wouldn't worry about it; especially if you off road at all, as you'll likely be airing down and back up often.

    If it is nitrogen and you want to keep it nitrogen you could always buy yourself a tank and have it topped off at a welding shop when it runs empty. If you just want to top them off there is no issue with topping them off with a normal air compressor.

    Remember- Nitrogen is makes up appx 78% of the air we breathe

    So, a “nitrogen fill” is only 22% more Nitrogen than we already breathe.

    When wheeling, after airing down- I refill with my CO2 tank.

    No discernible difference. Hope it helps!

    As mentioned, it's fine to top nitrogen filled tires with regular air. I always figure I'm gonna have to top off a tire somewhere, sometime, and nitrogen won't be available anyway. So why bother with nitrogen in the first place.
