depends what you want the tire to do... if you want it to harden up a tad over winter let it be.... if you want to preserve it “ and I know I’ll get castrated for this one” spray it down with WD40 to put some oil back in it or prep and atf or a conditioning prep like many sell with heavy oils in it and let it be till spring. 9 chances out of 10 your gonna deglaze everything before the season anyhow. I use blacksand a lot and that’s what I normally do to mine.
