    Wow that's the most I've heard of the stock tires lasting. When I bought my '09 it had the originals w/22k on them and they were toast.

There's a Discount Tire here in Henderson, Boulder Highway & Lake Mead, that I've dealt with and they will match Tire Rack prices. I've always had good luck with Bridgestone and will probably go with Potenza S-04 Pole Positions too.
    +1 on Discount Tire. I use the one on Silverado Ranch and Eastern. Manager is Brian, he takes very, very good care of us. We've actually followed him when he's moved from store to store.

    Well, let me make this perfectly clear about my 29K tires of the 2010 V Sedan, are these Michelin Pilot Sport PS2"s?

    No. These are a brand new model year tire in a brand new size. At most, the oldest PSS in this size is less than a year old. They only introduced the tire itself from mid 2012 or so.

    Need new tires soon. How did the PSS compare to the PS2 as I'm thinking of trying the PSS this go around???
    there is, absolutely no reason to buy the PS2. The PSS is cheaper, better in traction in every aspect, and lasts longer. I put these on my S4, they're fantastic.

    Re: Pilot Super Sports tire wear pics

    Tires wear out both due to tread wear (obvious) and heat cycling (not obvious to most people). Every time you bring a tire up to operating temp and then let it cool, the rubber hardens. It's essentially vulcanizing still. After many heat cycles, you have a harder tire with lower grip. You've heat cycled a 25k mile tire hundreds of times.

    It's more noticeable on race tires. Plenty of people with R-comps purchase their tires shaved for better performance and get them heat cycled by the retailer (e.g. TireRack) a few times so they don't chunk the first time they track them and last longer. It's common to replace an R-comp tire before they're worn down simply due to heat cycling. This is why people use a durometer on their tires to assess their age, useful life, and amount of wear.

    Re: Pilot Super Sports tire wear pics

    That makes sense, thanks spearfish. And it raises an interesting point - it means there's a performance ceiling in terms of treadwear, so there really is no point in trying to get a performance tire beyond 300TW because at that point it's been heat cycled so many times it doesn't matter if you have tread left or not, the grip is gone regardless.

    The S-04s I have on my V now are close, they have a TW280 rating and with heat cycling in mind I bet there's no need for it to be higher than that since they'll lose their grip by the time the tread wears down. I didn't even think of using a durometer on my PSSes before taking them off.

    Keep in mind that tire treadwear ratings are only consistent when comparing tires from the same manufacturer. Using treadwear ratings to compare a tire from one manufacturer to a tire made by a different manufacturer doesn't hold water since each manufacturer sets their own standard or baseline wear rating for their tires.

    Best regards,

    FWIW the tires are broken in now and they definitely got stickier. Really enjoying having some traction again, it's fantastic.

    I'm probably replacing my Ps2's with super sports when done as well. I don't like how my tires looked after the trackday but I still have tread left haha.

    Good to hear discount tire is good. I have one near me on torrance and needed a place to replace my tires.
