they put simple green inside the tire tubs to soften up the compound
flaming the tires burns off the chemicals on the tires when you open them from the package. also when you flame them, they heat up, then you quickly apply buggy grip, death grip, etc...
but i usually just brush off my tires in a tire tub with some simple green, dry them off, apply death grip when dry. works fine with my t4
o yeah, use trinity bomb one inserts because alot of the other foams quickly deteriorate with water
