Tyre killers, installed at Pune's Amanora Park Town to check wrong side driving were removed on Tuesday. The move came after Pune Traffic Police sent a notice to management of the township calling the tyre killers risky. Tyre killers are essentially a metal strip that acts as a speed breaker for the person driving on the right side, but its spikes puncture the tyres of vehicles coming from the wrong side. It was installed a month ago at a cost of about Rs 1.75 lakh.
