Here's some custom made special Tire textures of the ones NASCAR uses for the Coke 600 and the throwback weekend. Can be used in game and in car viewer. Just remember to save a copy of the original and rename the new texture. NOTE: The Support our troops tire is the tire from 2016 I couldn't find a 2018. Also please Note these are in .bmp format you'll have to .mip them yourself. These are for Carveiwer but they should work for the actual game.
