So can somebody please explain to me how this happened since I'm not all that great with computers..

I was searching for some trailer tires on eBay I was getting some prices together and then I get a notification from Amazon a few days later stating you recently viewed these tires and it had a price and time of date when they could be shipped to me and in another notification it said these tires will not fit my car that stated the year make and model my question is how in the hell did they know what kind of car I have and what I look at on eBay?
