More developments, guys
The tire supply in the "+7" options is much worse than I imagined, for several reasons:
-Old tires with little existing demand/stock
-Few 15"'s available
-Supply chain issues - all Japanese tires
Here's what I have for inventories (verified by calls myself) from the largest retailers.
Tire Rack has 12 Victoracers in stock, no future availability. AO48 - 8 tires, no future availability
Discount Tire has 37 Nittos, 11 inbound, then no future availability.
This was brought up earlier, and I apologize for not investigating this more than looking at websites to this point. At this point, I'm not sure the +7 option is viable through the year, stay tuned....
