    New tires installed last week--flat today!

    Just bitchin. Waiting at a gas station for a tow.

    Had some General G-Max AS 03s put on the car last week. Road force balanced and everything.

    The one odd thing is that the installer insisted on inflating them to 36
    PSI. Could that have contributed?

    Probably a loose TPMS

    Generally the Tire pressure sticker on the door only refers to the OE tire (Goodyear F1 runflats? ). As soon as you put something different on your car that sticker can pretty much be thrown out as every tire manufacturer has different sidewall construction, tread compound and internal material overlays that will have different ride characteristics. A runflat has an extra layer of sidewall so generally doesn't need as much pressure to maintain an even contact patch. Going to a non-runflat tire it would be recommended that you increase your tire pressure a few psi.

    If you are finding that the vehicle ride has become harsh at 36psi drop the pressure down a couple psi. It'll pretty much be trial an error. Keep an eye on tire wear and you should be fine. I run my 245/45R18 Michelin Super Sports at 30-32 psi and the ride is great.

    Because the last two sets of tires I've got (two different places)..., they didn't tighten the TPMS and I had flats..

    No, not in the dark. I had it towed to the shop that installed it. Do any of you guys know what it takes to get a replacement under warranty if the tire was defective? I bought then through tire rack and had them installed by a preferred installer.

    You most likely have a small puncture or the only other place that it could leak is the tpms/valve stem. In either case you won't be getting a replacement tire. Just have the shop pull the nail if it exists and install a plug and vulcanize the inside of the tire where the puncture is, then put a patch over it. If it turns out there is no puncture and you are still losing air, I would have the shop dismount the tire and clean up the rim bead of any corrosion (they should have done that before mounting the tires) and remount. I had a slow leak on one of my other cars tires and it turned out to be a cracked wheel!

    Generally the only time a manufacturer will replace the tire is if you have an unusual malformation in the sidewall or if the tread cap is delaminating from the tire carcass.

    You drive a car, you are more than likely to run over stuff. Punctures can happen on old tires and new. You most likely just have a case of bad luck. Either way the tire will most likely be able to be fixed without any durability concerns if you can't visually see any gouges in it.

    Re: New tires installed last week--flat today!

    Thanks for this great detail. Unfortunately, I could tell the tire was toast, even in the dark. It was actually my wife driving, with our baby in the car, and she had to drive it about 1/4 mile from the off-ramp to a gas station that was the first safe place to pull over. It was either that short drive or the puncture itself, but I could see the sidewall was ripped in at least one place.

    You know a lot about tires, and you explain yourself well. Indeed, the ride on the General G-Max's at 36 PSI was awesome. Much better grip, better cornering and smoother ride than the previous summer tires I had on there at 32 PSI.

    Did you get TR's road hazard?

    If it went down quickly and you have working TPMS, then it was probably a major catastrophic tire destruction. Did she notice any warning lights from low pressure?

    TR may work with you even if you don't have road hazard...

    No, I didn't buy road hazard

    She didn't notice anything until the tire went out. She said it was like a sudden thwoosh, like a giant balloon ripping a fart.

    Hopefully TR can work with me.

    Bummer on the no road hazard. Hopefully they will work with you.

    I buy all my tires and wheels from Discount tire, even if they don't have them they will just buy them from tirerack or wherever online, pricematch and offer any promotions that currently are running and apply them to my purchase. I used to buy the road hazards, but found that they still pro-rate the tires even if you have a flat or catastrophic failure. I had a snow tire with a sidewall tear from a pothole. Brought it in and they said it only had 1/32" wear on it so they pro-rated it using whatever calculation they have and I only had to pay $20 for the new tire, and they balanced and installed for free.

    Re: New tires installed last week--flat today!

    I'm going with leaking TPMS = running at lower than normal pressure for a while = sidewall failure. You won't get a low pressure alarm until somewhere around 20#, so if you don't pay attention you can drive around on an underinflated tire without getting an alarm.
