Brought in my brand new goodyear super z tire with a nail in the thread. 75.oo dollars later I thought it was fixed. Went flat again the next day, was told it was a three hour wait. Went to Discount, they fixed it for free after pointing out Big O had scraped the area down to a dangerous level and tire may need to be replaced. \n\nBIG O you got my 75.00 dollars, Hopefully anyone reading this will go to Discount Instead. You guys suck.
