The original price posted was for tires that had a 'D' rating. The tire that is now listed is an 'E' rated tire. I assume that they are out of the 'D' tire due to the low price.
As a side note, Discount Tire
matched the original price that I first posted to the 'E' rated tire. According to them, the 'D' is no longer available??? No complaints from me though. The 'E' tires that I got look awesome, don't ride rough (that was my first concern), and they are BSW only so no white lettering showing up on the inner side of the tires.
I was out the door from Discount Tire for $700.00 plus tax. They are running a $70.00 mail in discount so figure $630.00 plus tax. Still not a bad deal in my book. My wife on the other hand wants to know why I need new tires when I have 1500 miles on the original OEM ones.
