Need Prius tire in Vancouver

[fotomickey]

Such bad luck

Last night I discover my Right-Rear Tire caught a nail near the sidewall (not repairble) after shopping @ Costco. It was indented in an odd angle.... almost sugggest its not accidential.

I been search all morning for replacement tire (everyone include Toyota said back-ordered... some tire store says 5+ weeks or even no ETA)

1) Is it such a special or new tire that not even Bridgestone nor Toyota stock them in Canada ?

2) Where-else should I call for better chance to get the tire.

3) If I mix brand replace both rear tires (using another brand for rear Axle) will that confuse the Vehicle Stability Control / ABS / Tire pressure sensor ? and what about the MPG effect ?.... any alternative brand or model recommendation ?

4) With the gas price frustrations, I wonder if Prius now becoming vandalising target ...if it is true ... that may also explain why this tire on shortage

Please give some advise :-)
Thanks
