Holy Crap john!!!! Thats must of taken you forever!!! Not to mention the huge amounts of black dust you had to have everywhere!!!! Impressive work though!!!

Ive seen guys just round out the edge of the tread bar... They would take the edge off and round the tread bar into the carcass/sidewall.. It seemed to work well Dirtdawg3 and gsmaxx both had tires like that for racing
