    If it was me, I would buy two Toyos. Have the America's Tire guy determine which of your three remaining tires is most worn and replace that one. Then put the two new tires on the rear.

    Can't do that on an AWD system if there's too much variance in tread depth between all four tires, you'll burn out the system. Best thing to do is get a shaved tire from Tire Rack (been there, done that) or four new tires. O/P, I'm guessing there's a sidewall leak or a leak near the edge of the tread that's preventing a fix?

    Why on the rear? If it was FWD, I'd put two new ones on the front, not the rear.

    Every professional recommendation that I've seen states to put the newest/best tires on the rear; regardless of drive wheels.
    Quote from Tire Rack:

    When tires are replaced in pairs in situations like these, the new tires should always be installed on the rear axle and the partially worn tires moved to the front.
    New tires on the rear axle help the driver more easily maintain control on wet roads since deeper treaded tires are better at resisting hydroplaning.

    Most major tire companies will install new pair of tires on rear if you only need two on a FWD vehicle. Discount Tire told me it's based on recommendation by Michelin.

    But like you, I'd move the new tires to front after installation simply because the front tire wear much faster than the rear on FWD vehicle. Hopefully the tread depth will be even out at certain point, and I'd rotate all 4 tires regularly.

    Luckily I rotate tires frequently and I haven't had such situation for a long time.

    Thanks for posting that.

    But I don't understand the rationale. The fronts steer and carry most of the weight. Wouldn't they be just as susceptible to hydroplaning as the rears? And if so, I'd rather have the rears break traction than the fronts.

    What am I missing?

    I don't think you missed anything. I asked the same question to my Discount Tire, and the answer was that's Michelin's recommendation based on their experiment. IMO front tire is always more important than rear, that's why Mazda suggests we can only put tiny spare on the rear. So I moved new tires to front by myself, after Discount Tire installed the new pair of tires to the rear.

    If the front tires break loose before the rears, you get understeer. If the rears break before the front, you get oversteer. Understeer is easier to correct compared to oversteer, thus it is the safer option. That's why all tire repair shops and tire manufacturers will always recommend that a new pair of tires always goes on the rear.

    The spare is a totally different scenario. Because the spare is smaller in diameter and in width, the safe handling characteristics of the car are severely compromised with the spare up front (vs. a more worn tire up front that simply provides less grip). Also, most drivers with common sense understand that you should be driving more carefully/slowly with a spare tire on your car, so the issues with understeer and oversteer are much, much less likely to be a concern.

    For those who have lived long enough should remember that tire manufactures and shops used to recommend a new pair of tires always goes to the front for the reason shadonoz stated earlier Ö

    That's great, but do you disagree with the reasoning RE: understeer vs. oversteer?

    Seat belts used to be optional as well. Things change. If you want to stick to the old unsafe way, that's your prerogative. The reasons for putting a new pair of tires on the rear vs. on the front makes perfect sense to me, and tire manufacturers and tire shops currently recommend the same. I'll take their word and common sense over what used to be recommended (who knows how many) years ago.

    This was also the recommendation at Americaís Tire, put two in the back. Unfortunately I just got the one tire to replace the busted one.

    My tires are rotated every six months by the Mazda dealer, at the time of my check up.
