Each order includes a set of 4 tire decals. These Firestone tire stickers are sized for 1/10th scale RC tires with a rim diameter of 26 to 31mm (roughly 1-1/4″). These fit HPI racing tires especially well, like models 3858, 4797, 3741 and 5130. These are a one piece peel and stick application.
Installation: use a non-chemical or oil based cleaner like 50-70% isopropyl alcohol to wipe any residue from the tires to give the best adhesion. For low stick surfaces consider a dab of tire glue behind the decal to make sure it adheres long term.
