Gents,
I finally got my oversized tires installed on the wife's 2008 BMW X5 3.0si. I installed a set of Custom Ceika Performance Coilovers that gave me a .75" lift on all four corners. I then installed some Falken Wildpeak AT3W tires in 265/60R18 on the stock 18x8.5" rims. These are 30.5" diameter tires compared to the 29.3" diameter stock 255/55R18.
I was worried the tires were going to be super noisy, but they are just barely louder. I can't imagine they are louder than stock run flats, but have a nice soft ride.
Overall I'm happy with the tires. I thought they would look a little more dramatic, but they pretty much look stock.
