Defect Investigations and Recalls - Transport Canada
As I previously posted, I sent in all the required information, got a reply back from Transport Canada saying it will be actioned, and have yet to hear anything from anyone. (2 years this September) . I have upgraded the tires to LR Es running at 65 psi so the tire information on my sidewall is void anyway, and I don't plan to sell or trade in the near future. It soon won't be an issue, since in another year the sun will have faded the sticker to the point nobody can read it anyway.
