    Flat tire AGAIN on my M3 with 18s. Lemme ask you this:

    SOB! The dash lights up, I pull over, tires low, I fill with air, reset the TPM and drive off. Ten minutes later same thing: I jack it up and remove tire, I find a drywall screw, I push a plug in the hole I reinflate remount tire I drive way. The car is sitting in the garage now, I'll will have it patched from inside on Monday.

    Now with the 997, I plan to do the same thing.

    Here's my issue: With the 19s and no TPM How much time will we have to figure out the tire is flat and we are about to tear up the wheel?

    I figure without the TPMonitor, the tire is gonna be destroyed on the inside by the time I hear a "flub flub, or a bump bump, or thud thud.

    I HOPE to hear all this before I hear the wheel getting destroyed.

    Do you have any thoughts on what will happen, what we will experience, with these 19 inch wheels when they get a puncture and slow leak?

    Doesn't look like it's gonna be easy

    Re: Flat tire AGAIN on my M3 with 18s. Lemme ask you this:

    To check for slow leaks, I do check tire pressure at least weekly.

    It's just I don't think I've ever heard a man whine so much before.

    Re: Flat tire AGAIN on my M3 with 18s. Lemme ask you this:

    If its a slow leak, not a blow-out, you will feel the car pull to one side way before "flub flub, or a bump bump, or thud thud" with current high perf tires and their stiff sidewall. I have had this happen twice, once with a 16" Michelin MXX3 and another with a 17" Bridg. S02.

    On the first one (MXX3) I was cruising in the highway at 200kph speeds with a slow leak and when I finally pulled over to see, the the top 50% of the "Michelin" letters on the sidewall were completely worn out and dissapeared On the S02's when I pulled out of the garage the tire was already pretty empty (leaked out over night) and on my way to work I noticed the car pulled to the gutter on acceleration but on under braking so I pulled over inmediatelly and sure enough the rear-right tire was almost flat (hence pulled to the right and under acceleration).

    So from my experience its detected before damaging any wheel or flub-flub in either case, a blow-out is a different thing but never had one of those so...

    Re: Flat tire AGAIN on my M3 with 18s. Lemme ask you this:

    With 19 inch tires, its hard to feel a tire with low pressure. Please Porsche, include TPM.

    That's good to hear what you explained Carlos. Thanks, even with such a narrow sidewall it still sounds like there's a decent safety margin for at least the wheel built in. Kinda makes sense now also since the 997S steering is so sensitive any trouble with the front wheels should be quickly evident.

    Re: Flat tire AGAIN on my M3 with 18s. Lemme ask you this:

    Even though thats been my experience, I agree with what you say though, the TMP is a MUST option for the 997S and hope they start offering it soon, its so much safer that way, period.
    And much more convenient not having to check pressures frequently in order to maintain closest to optimum performance pressures all the time.

    Re: Flat tire AGAIN on my M3 with 18s. Lemme ask you this:

    There's a new accessory out that mounts on the tire stem and changes color if the tire pressure falls below a certain threshold. It's only $17.95 - I just saw an article in one of this month's/week's car magazines but can't remember which. In the article they say the company is working on an in-car receiver that will receive signals from the tire stem accessory and warn the driver while in the car. Not sure what the Porsche OEM option costs but this aftermarket setup sounds pretty cheap and if it works as promised this could be your solution.

    Re: Flat tire AGAIN on my M3 with 18s. Lemme ask you this:

    pirelli has a wireless tpm ,you just have to install something in the tyre and you have an audible and visual signal in case of air loss ,the screen shows the pressure in each tyre. no wiring needed its fully wireless

    Re: Flat tire AGAIN on my M3 with 18s. Lemme ask you this:

    Sell your M3 and get a 997. The 997 doesn't get a flat tire that easy, must be a BMW design flaw or something...
