Thanks Sam. That did cross my mind but it would increase the diameter as follows:
275/40/19 = 702.6mm diameter
275/35/20 = 700.5mm diameter
285/35/20 = 707.5mm diameter
Thats quite a difference. As it is, our speedometer reading is approximately 5% off the actual speed (as compared against a satellite based GPS). Diameter difference of +5mm from the original 19 inch wheels will increase your ride height by 2.5mm
Anyway, all those calculations aside, I felt better running on 275s bearing in mind cost and petrol consumption
