My experience is bigger farm tractors, but it should be the same on compact tires:
Really, really bad for the tire. It _needs_ the air pocket to handle the shock loads of traction, bumps, etc. I would get 1/4 of that fluid out as soon as possible. You can check with your tire manufaturer, probably even on the web, but I'm sure they will say the same. You always want a 25% air pocket. Liquids expand with heat, if it warms up 40 degrees where you are, you could easily split a tire or rim -something has to give, & liquids don't compress. IMHO
I'm not a big fan of antifreeze, now you need to dispose of it safely. Really bad for the environment if you just dump it.
But be kind to your tires, and get some air in there.
