Crap! I'm at the tire shop.
They mounted the new tires and I went out to look at them. They put the HR2 on there instead of the RS2 like I asked for.
They've never heard of the RS2/Z212 and neither has their distributor. They're putting my 3 RE92s back on there and my doughnut spare.
I should have just ordered them from DiscountTire since the shipping is free anyway. Now I won't have tires until next week at the earliest.
