Oldblu49...we / you need to get in touch with a brother Bolter who lives in Washington State and who is planning to visit Victoria in the upcoming months.
They could bring the bias-plys you need and paid for by you in advance.. you can give them a special tour around Victoria and everybody wins.You save duties , brokerage fees, freight and other shipping charges.
Old tires are expensive...don't ask me...I know!
