Any one had this done? Do you see any benefits over standard Air?
Just been down to my local costco, and they do it for free just for been a member!, Dont even have to buy tyres from them, can just do your existing tyres. They also do it properly from standard air by deflating then refilling a couple of times to dilute what's in the tyre already.
Well worth trying it imo if its free Told me to call down in 4 weeks to have them done again (deflated inflated) then return ever 8 weeks for a pressure check/top up completly free. Im there at least once per month anyway so no harm for me to just hand keys over, go shop enjoy a hot dog and collect car when done
