Hi Adrian;
That's a lot of money for tires! When I called my insurance agent to have my full coverage reinstated, he told me about a web site called 1010tires. He also said I was the third Crossfire owner to call that day! He told me about his high perfromance vehicle and said there were lots of reasonable options to the Goodyear and Michelin. I am researching still....I'll let you know what I come up with.
Tiretrack is an option but with the exchange rate, it's not an attractive option. I visit potential employers as part of my job and yesterday, a senior manager with CRA (it's the Canadian equivalent of the IRS) told me to do the same thing, drive across the border to buy my tires.
