WD-40. It probably isn't tar, it is primer, or emulsiphied asphalt. I'm an engineer and I have done a lot of paving, we always use WD-40 on a rag and wipe it off. Or, I should have said this first, try fabric softener. To clean the trucks we use fabric softener in the dump truck beds. The workers all use diesel fuel to clean their boot soles, but fabric softener is safer and smells less.
