Just done the tire height calcs myself and there is almost no difference in balance as follows:

OEM tires

Front 245 / 40 = 98mm, Rear = 275 / 35 = 96.25mm

The front tire height is therefore 1.75mm higher than rear on OEM tires and this is balanced as per car design.

Oversized tires

Front = 265 / 35 = 92.75mm, Rear = 91.5mm

The front tire height is therefore 1.25mm higher than rear which is only 0.5mm different to OEM tires?

I'm now unsure again on why the car feels so vague and floaty at high speed?
