Armorall Extreme Tire Shine GEL, put this on blackwalls a couple of years ago. Slowly began to notice the tires appeared to be checked and turned a mustard brown color. It was this product oxidizing on the surface of the tires. Had to scrub like a banshee to get the stuff off and now the tires look nice again.......
Used no prep on my Universal tires and they turned a brown color. Are you so sure it's the stuff you are putting on and it is not just the rubber used?
Look up tires turning brown on the internet.
