It will do the trick, and you will need to use it again.
I,ve not had any probs with my current ioniq until the first cold day last year. The tpm showed low pressures and i just went to asda air line an done all the tyres. I cant remember the exact figure but the Ioniq 5 has some ridiculous tyre pressure something like 45 psi.
But the inflator is there if you need to use it.
