I am going to attempt to prep my own tires this year in order to save money. I've run asphalt pretty much exclusively in order to avoid the tire prepping debacles. My question is what's your process? For this thread, I am not really looking for what chemicals or products you use, as much as the physical steps. My initial questions are: do I need a hotbox, or can I get away with a roller for the time being? Inside vs outside prep? Time? When to do what? Thanks for your help in advance.
