I just ordered four Bridgestone Blizzak WS-50 (225-55-16) from Tire Rack.
They were on sale for $90 EACH! (Close out sale as the WS-60 are comming in)
The total price with GST, PST, Duty, shipping, and brokerage is $542, or $138 per tire delivered to my door. PLUS, with the dollar at 1.03, take off ~$16.
tiretrends.com wants $138 per tire, and with shipping and tax = $681. (Saving $155!!!)
Tire Rack really makes it easy to business with them!
