Can I remove the wheel valve when painting?

[Mixersmate]

Hi everyone -

I bought a used GP Steel for use as a spare and it came with a valve in, I was hoping to give the wheel a quick shot blast and a coat of Hammerite before confining it to a life under the van. Can I remove this valve myself, if I damage it during removal can a tyre place just fit a new one?

Also does 235/55/17 sound right for the spare wheel carrier?
Thanks guys.

just cut the back with a stanley knife, tyre place will fit a new one when the tyre goes back on
