White letter problem with bf goodrich tires

What you do is call bf good rich which has been bought out by michillen.I explained the problem they said they knew they have a problem.She took my zip code and called a dealer that sells there tires.They told them to give me a new set under warranty.And i think she said they are under warranty for 6 years.I did not even by my tires from a bf good rich dealer but they have to warranty the tires because they are a bf goodrich dealer.I took them back to tire discounters
