The tire techs will inspect, balance, top off, etc. the tires you bought there, on request.
They're going to take their sweet time doing it too, expecting that you'll be inside spending rather than waiting. I'm fine with that, I like browsing Costco so usually only go when I've got enough time to do so
Thanks for this information..next time, I will get my tires from Costco..my tires are pretty okay at the moment...
