2013 Porsche 911 Carrera Cabriolet Long-Term Road Test


2013 Porsche 911 Carrera Cabriolet: Flat Tire, Part 2

March 12, 2013

2013 Porsche 911 Carrera Cabriolet

After we had our 2013 Porsche 911 Carrera Cabriolet towed to Allen Tire in Lake Forest to fix its flat left rear tire, the next question was: What caused it?

As mentioned in the last update, I had spun the tire around, felt all the tread and couldn't find a nail or anything obvious. After some air was added, it turned out to be a cut sidewall. How exactly it got cut is not clear, but the fact the rim is also slightly bent points to hitting a pothole.

But that's a bit weird on two levels. First, I sure didn't think I hit any hole hard enough to bend a rim or cut a tire. Second, they don't even allow potholes down here in Orange County.

But the cut sidewall meant we needed a new tire. The tire shop was able to get a Pirelli PZero, size 295/30ZR20, to the store by the end of the day. With mounting and balancing, the total came to $661.38.

On the bright side, the 911 is back on the road and that slightly bent wheel doesn't seem to be a problem.

On the down side, those damn 20s.

    $600+ for a single tire, ouch. I could replace all 4 of the tires on my MG for half that. It's not really the 20" wheels that are the problem so much as the 35 aspect sidewalls that come with them. The 45's on my '04 Jetta aren't much hardier, but fortunately they are much cheaper.

  • Ow, that's a lot of money, at least the towing was free...

    yeah dam them dubs--I'm sure 18's provide a short enough sidewall and performance. But you should get better mileage now that your wallet is so much lighter

    That's funny noburgers! Sorry to hear that the tire cost you guys so much though.

    I'm not that sorry to hear that a ridiculously huge tire with a ridiculously slim sidewall cost that much. Giant wheels are dumb in an everyday car.

    If there ever was a convincing argument against low profile 20's, this would be it. 88.5mm sidewall height is a bit on the small side. The original 285 35/R19 rears would work a lot better since they have 99.75mm sidewalls. Typically 94-100mm sidewalls seem to be the best compromise between ride comfort/durability/stability and performance.

  • Damn...$600+ for one tire!?!?

    Have you driven that car on I-10? Like I-40 in Northern Arizona parts of I-10 are like driving offroad with a center divider.

    @agentorange i agree! I10 is not any better here in alabama there are sections where the speed limit is 45mph(!) due to so much construction and there are huge gaps in places that are actual speed bumps you have to hit the brakes hard for. funny seeing ou
