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.
