Maybe this is another discussion topic, but when replacing tires, I have learned the importance of a good road hazard warranty, particularly for Subarus. I have purchased numerous sets of tires from my local Sams club for my two outbacks and soon will be looking at replacement tires for a 2020 Ascent. Their road hazard warranty includes the usual lifetime rotation, balancing and tire repairs. However, on two occasions, my wife's outback had a flat tire that was determined to be unrepairable (puncture too close to the sidewall). They of course will replace the unrepairable tire, but also recommended replacing the three other tires. The one defective tire was replaced in full, but they offered a prorated price to replace the remaining three tires. It was prorated based on remaining tread/mileage and I think they were pretty generous about how much tread was remaining. Bottom line, I got 4 new tires because one tire was not repairable and only had to pay about a 1/4 of the full cost because of the Sams club warranty. I don't know if this is standard for all Sams clubs or just the one in my town, but it was not a fluke bc is happened twice to my wife's outback. I'm not sure if other tires shops will provide this type of replacement warranty. Given Subaru sensitivity of having 4 tires with same tread depth maybe others can provide recommendations on best places to buy tires that have good road hazard warranties. I have had exceptional experience with the road hazard warranty at my local Sams club and will continued to buy tires there.
