These are high quality Vinyl Decals designed for 1/5 scale tires.
These decals come in a set of 4- (*one complete set does 4 tires).
They were originally designed for BRP racing tires but will work on other smooth tire surfaces similar in size. They come on transfer paper already shaped to the wheel ready to be pressed into place. They will typically stay but for longevity, you may want to use decal glue/nail polish as well to keep decals from coming off from use.
