Crazy question regarding air tank...

A couple years ago I briefly took up the hobby of shooting PCP (pre-charged pneumatic) airguns. This eventually led to me purchasing my own compressor and air tank for quick refills. I have since lost interest in that particular hobby and am wondering if I could repurpose the rather expensive tank and compressor for airing up my tires after offroading. The tank is a 1.6 liter that I fill to 4000 PSI with the compressor. This tank can fill one of the air rifles about six or seven times to 3000 PSI. Each fill gives about 30-35 full power shots. In other words, it's a crap ton of air. I am thinking it would make quick work of airing my tires back up. Now, I know I will need some sort of regulator so I don't explode my tires lol. Can anyone steer me to what I may need?

 

Sure, it's just air but for safety you'll want kind of an odd regulator to get down to tire filling levels. This popped up in a quick search: https://palmerspursuit.com/products/boulder

 

Thanks! At least I know such things are available. That particular one looks to be OOS but I now have a compass to search for similar. Appreciate it!
