I agree with you on the cleaning aspect as many may not know to do this,But hear me out. I masked my tire off using automotive pin striping to get a cleaner edge then primed the tire with "Spray" KILZ to seal the surface from any bleed through from the tire's chemical compounds.Then I sprayed it with White "Plasti-Dip" that comes in spray form. Because it is a latex based product it will not crack and looks awesome. Krylon will work but because it is not a latex based product it will crack over time!!! Be Blessed, Warren
