15 year old tire sensors are the Achilles Heal of the Beast

[tenedios]

I am a new member and own a 1991 ZR1. I just want to convey to you folks a "safety" concern. I was travelling close to where life begins and suddenly the car vibrated to either side of the road. It shook sideways violently. I thought I blew a tire. I managed to coast down and pull to the side of the road. No flat tires but I could not even proceed home at speeds greater than 55 without the car vibrating. At very low speeds I heard a clanking sound and thought it was the brake calipers.I wondered if I lost a wheel weight and was out of balance. My mechanic pulled the tires and the left front sensor and right rear sensor had cracked apart from the metal banding which held the sensors in place. The plastic housing were apart and the electronic circuit boards were freely floating in the tire. It seems that the 15 year old plastic sensor could not take the high angular velocity. I pulled out all the sensors. A lesson learned.
