Going to a wider tire (275, 285) with a lower profile (50) will keep you at about the same height. What gets most people is that the series number represents sidewall height as a percentage of width. So the sidewall height of a stock 245/60 tire is 147mm whereas the height of a 285/50 is 142.5mm. Not a big difference at 4.5mm.

Keep in mind the wider you go the poorer your fuel economy and handling will become. Anything much over 255 tends to "hunt" the road crown, especially on the SWB VX. To reduce the tendency you need to lower the air pressure which then increases the friction drag giving you a mileage hit.

Looking cool ain't cheap!
