no, youre not grasping how this works. The rolling radius is in relation to the the width/profile of the wheel, the 35 is a percentage of the width. From the front to the back there is a ratio for the rolling radius. The car detects how quick the front wheels are spinning and the rear wheels are spinning, if the speed is out too much then the traction control go's haywire. If its shitty front tyres on them bin them, if its premier range then sell them on here. Somebody may pick them up. 235 even looks stretched on a 8.5j rim so I imagine that your fronts look very stretch on a 9j rim.
What make of tyres are on the front ?
For 275/35/19 to work you're looking at 245 or 235/35/19 to stop the traction control getting upset.
