part of the confusion:
In Canada, there is an auto store called: Canadian Tire
That was my first thought, but he spelled tire with a lower case T, so I think he is looking for a source of the tire he wants in other than V rating, but they don't have them in the US. Unless he's on a trip in Canada and needs a new tire now.
But I'm in Vancouver, and he's in Jersey (east coast) and I don't know if the same tire stores here are the same as the east coast (other than Canadian Tire).
I haven't found ContiGo, but have found Continentals at Canadian Tire.
