> If I go to Costco and see an advertisement for tires... well, I’m at Costco, where I buy stuff. Things are sold at Costco and people go there to have things sold to them
If you visit content on the internet that the Google Ad network thinks suggest you might be interested in purchasing new tyres, then showing you ads for companies that sells tyres is, unfortunately, relevant no matter what your doing now, because you're more likely to click them, or remember the company/brand when choosing a purchase.
Also a large proportion of ads aren't designed to affect immediate purchase - cars, movies, coca-cola, and other brands are hoping to get into your (sub) consciousness so you'll remember when you buy days, weeks or months later.
