Hey folks,
I'm just wondering if anyone knows if Costco does tire mounting and balancing for tires not purchased at Costco. Does anyone know how much they charge if they do offer this service?
I purchased some tires in the US and brought them back up to Canada and would like to get them installed this next weekend. I know Fountain Tire charges around $125 and I figured Costco might be a bit cheaper (and hopefully I could get it done while doing some shopping if I get to the store right as they open.)
Thanks.
