Prius 2013 Front Vibrating when slow driving

My Prius is 2013 My-Coordination version.

Few weeks ago when I was on expressway driving 100kmph suddenly I felt small vibration something like front tires are loosened. Stopped the car & checked all were ok. In this morning it happened again when slow driving & car was shaking/vibrating madly with "daka-daka" noise. Front tyres are not much good (too much worn-out) & need to replace. But a technician said it could be due to engine miss-fire because of one of Coil's issue. Any idea about this?

 

Hi thank you for relying.

Ut happened 10mins after driving when i took an elbow turn to expressway. Happened with a big honking like sound. After that it started to front vibrating. Didn't find anything unusual except bad front tyres which ones edge has gone. When phoned to a tech guy he asked it is shaking going bit fast. I checked and found it doesn't shake when speed upto 40kmph. When drived 5kmph it shaked again. So he said it might be engine misfire due to a bad Coil. And if its the case i have to replace it. Anyhow i got exited from the expressway at 60kmph and came to office. But 5 hrs later or in next trip car drived smoothly again in low or normal speed. Didn't drive fast actually. Still couldn't see a tech guy. Can this be due to bad plug or bad coil? Or any idea pl?
