Help from Hometalkers--"I painted several tires in bright colors for outdoor planters. Before painting, I brushed them down with a mixture of dish soap and hot water, then hosed off the soapy water. Then I spray painted in bright colors with exterior spray paint, no priming. I have had them outside for 3 years and they are still bright and beautiful". https://www.hometalk.com/diy/paint/exteriors/q-painting-types-tires-23936708 ANOTHER--" I do a lot of tire yard art and I use spray paint. I would say that 90% of the time spray paint works. If you flip a tire inside out you have to clean it really well before using any paint. I have stuff that has been outside for years and the spray paint looks just like it did when I painted it. Good luck". https://www.hometalk.com/diy/paint/exteriors/q-want-to-paint-a-bunch-of-tires-what-is-the-best-paint-that-lasts-7200036
