Totally agree, I used to run with a brand called 'Double Star" ( some china brand) the size is 225/17/45, my car had serious under steer in dry condition, and like a floating boat in the wet, it can be easy to slide out just using 1/3 throttle.
It is always YOU PAY WHAT YOU GET, no matter how many horse power you've got, at last it is those four wheels to run the power, don't save for a hundred and lost a few thousand.
