The steering wheels was shaking when drive 80km or above. More important is safety concern when drive 90km on highway, the vehicle sway left and right which constantly require very focus attention to correct back to lane and holding steering wheel firm. At first, I thought it could be strong wind but when met up my brother in law on the 3rd day, who is car mechanic in Melbourne, told us the tire is worn out and cannot drive fast, as it is dangerous. Thus, throughout the trip was negative experience driving at slow speed which wasted alot of time at long distant travel. Suggest your mechanic check the wheel condition and shakyness of the steering wheel as poise safety concern.
