Pre-Pre-Last Call: Feeling Deflated?

We all know that dull feeling in the pit of our stomach when we know that one of our tyres has taken a hit. Whether it’s a sudden violent shaking and having to fight to bring the car to a safe halt that tells you, or a polite warning light on the dash letting you know about “air pressure low”, it’s never a particularly enjoyable experience.

This one guy, though, came into where I work for a day job complaining about a “tinkling, metallic” noise from his offside rear. The image above is what we found. Yes, that unidentified bent metal prong had penetrated his tyre and alloy AMG wheel rim, and the noise he heard was it tapping against the brake caliper as the wheel turned.

Amazingly; the tyre was still holding pressure perfectly.

  1. Is this something that happens a lot to AMG rims? I ask because I was in an AMG Mercedes last year when a noise erupted like a Spitfire had shot off the hindquarters. Turned out a bolt had gotten sucked up off the roadway and into the rim, then completely demolished the rim and come out through the tire.

    1. Not so much a AMG thing but a low profile tire thing. Very common for a rim to be ruined when a very low profile tire strikes something and has a puncture. It doesn't help the rims are very light and thin to begin with.

    1. I figured that it was probably a RFT tire… No pressure needed (for 50 miles or so).

  2. So what's the weirdest thing you've gotten jammed into a tire?
    For me, it was half a circular saw blade.
    My dad once got a bicycle handlebar through the tire on his Explorer.

      1. Everytime I see the KV's spinny and hold-together parts, I am astounded anew at how really awful a car that is.

    1. I once picked up a spark plug in an intersection while borrowing my brother in laws jeep cherokee. It made a tremendous racket and was still sticking out of the tire when I pulled over to look at it. Cost me 100 bucks for a tire that wasn't mine, even though it was my responsibility. Of course, when I went to pull the jack out from under the back seat I found coolant back there so I also had to tell him his heater core had headed south.

  3. A buddy of mine was deer hunting in the wilds here in Colorado a few years back. He had a new set of Armstrong Norseman installed on his Bronco before the trip. He came back a few days later with his whitetail and a flat Norseman tire. While tracking his antlered prey off-road up a coulee he noticed the steering was pulling badly. Says he stopped to check for damage and found a stainless steel strip from a wiper blade insert sticking in the sidewall of the l/f tire inducing a loss of air pressure. Glad I wasn't there to hear him change the flat. He took the offending Norseman back to the dealer which replaced it for a nominal fee. The s/s insert strip was mounted on a pegboard with other articles the techs had removed from tires including railroad spikes, a 16p nail, assorted sharp objects, a pair of needle nose pliers, and a small crowbar !
