Agree, true 132s are staggered, and tire brands are limited and not cheap...
Have Michey Diamaris on mine: they are OK, though the meaty block tread is not what I would consider a 'summer tire', but maybe the Michey engineers know something I don't...
Good shape OEs are not cheap either: have seen several sets with curb rash, few with little to none. I copped my set several years ago from an old poster here. They were pristine.
They look good, though I doubt they offer any benefit over the 18s with the sport pkg, other than cosmetics and more expensive tire replacement costs.
GL, mD
And, fwiw Style 63s were also on E53s, usually on the V8s, and as aftermkt add on mod for the non-V8s, IIRC. They too are staggered, but not my pick of looks.
