In September 2016 I had to buy new Michelin Primacy MXMW 245/45R19 98W BSW tires at around the 30,000 mile point even though they were warrantied for 45,000 miles. I got a pro-rated warranty credit from Discount Tire at the time. They charged me $296 each. Here it is May 2018 and I need new tires. I have only put 30,000 miles on the NEW replacement tires and the rears are at 2/32 and the fronts at 4/32. I took 'em in to get them rotated one last time and they won't rotate 'em. Here is the question: I noticed Michelin is now selling these exact tires DIRECT for $218.99 each. I paid $296 each (WITH a big discount) in 2016! So, how would a warranty credit work this time? If the replacement tire list price is substantially less than the old tires, how will it work? Anyone been in this situation?
