what is covered under manufacturer's warranty? I have my toyota corolla 2007 still covered not exceeded 36000 miles or 3 yrs, however I am not sure if tyre replacement is included (in case they need replacement). I am asking this question because one of the car tyre became flat yesterday and I went to fix the same at Walmart and got to know that the tire needs replacement as the cut on the tire is too close to the edge of the tire and for safety reasons it is recommended that new tyre be installed. Please help in my search for answers.
