So, it's almost been a year, and the fronts are down to the DW (no "S" left) and the rears are simply D... I will most likely need to replace these before winter. IIRC I was in the high 30's on mileage at the point of install, and now I'm at 51,xxx. So, not quite the forecast 50,000 miles but they've sure been grippy the whole time.

I'll look at my invoice to determine the exact mileage-to-date, but I can safely say I'll be testing the pro-rated pricing.

Or, since I paid for the road-hazard protection from Discount Tire, I'm tempted to stab them and get them replaced for free.

But I'm a nice guy.
