I bought 20" all seasons from TireRack, had them delivered to my house, and scheduled to have TireRack mobile service install them the same day my Lucid was delivered. Also, TireRack has free road hazard protection so gave me a free replacement tire when I hit a pothole this winter.
I have had good experiences with the mobile installers recommended on the Tire Rack website. Have the tires shipped directly to them and they will bring them to your house to install. They should not have a problem installing them on a Lucid. It is much more convenient than going to a tire service shop.
