I've been observing car tires prices for the last 12 months and here's what I found

Last year I needed new tires for my old Volvo. In Poland we have this very popular online tires shop: oponeo.pl.
Being naturally curious, I started tracking prices on that site and here are some interesting conclusions:

• prices change very often, typically every couple of days. I saw one summer tires, which - over just 8 days - went from 431 PLN to 654 PLN, and then back to 431 PLN. That's for single tire, typically you would need 4 of them ;)
• this means that it pays to be patient. Don't buy immediately, because you need them right now, today or tomorrow. Wait a bit, observe how the price changes - you can save a lot of money!
• also, it seems prices change depending on season: summer tires mentioned above were cheapest from Feb to Apr (300+ PLN) and more expensive from May to Jul (400-600 PLN)
• overall: it looks like it pays to buy summer tires during winter/spring season, and winter tires during summer/autumn. And also don't rush, don't pay the first price you see, take your time and observe how the price changes
