Ebay is offering free tire installation on a set of 4 tires purchased through 7/2/2023 (

Several tires are also being discounted on there. I've seen several brands with discounts between 25% and 36% (Goodyears seems to have the highest % discount that I've found) over the past few weeks. And yes, the two promotions are stackable.
I just ordered a set of Hankooks for the Prius C for $300 + tax, including free installation. Without the deals and with paying for installation myself it would've cost about $500.
Not paid to promote this -- just figured I'd share in case any of y'all need new tires and want to save some money at the same time. For me, the savings is about 5000 free miles, which is about 40% of my yearly driving.
