Toyota — toyota etios ground clearance

Address:

Uttara Kannada, Karnataka, 581301

I had purchased toyota etios gxd in the month of july 2018 for commercial purpose now it's 30, 000km run.
From the beginning i am facing the ground touches problem specially on humps. I am the owner and the driver for my etios. With 3 seats on the highway it's tough to drive the vehicle.
The advisor of toyota at the time of purchasing the vehicle told me it's same as first model etios only the front and back bumper is change but the tyres size is change from 15 inch to14inch which was not informed to me.
