Toyota — tyre getting fat for top end innova crysta

Address:

1192/D 6th Main A block 2nd Stage Rajajinagar, Bangalore, Karnataka, 560010

I brought my top end 2.8 z variant on 29 june 2019 from viva toyota hebbal bangalore. I have driven the vehicle only 3000 km and my left side front tyre has fat bump like over balloon. I am really disappointed from toyota.. The viva dealer also didn’t inform me about the problem. Please give me a solution. As per toyota there is change in mag size from 17 inches to 16 inches due to this complaint. But the dealer still sold me the 17th inches.
