4.6is vs 4.4i motors?

[TwinTurboGTR]

It's strange how it is listed as 5 calculated owners. Which dealer did you ask, Subaru or BMW? And the difference in tires between to 4.4 and the 4.6 is nil. That 4.4 is a sport packaged 4.4, so it has the style 63 wheels 19" staggered. Those Nexans look like summer perf's and now All season. The 4.6 yes has 20's staggered, but the difference you are going to see is pretty much nothing. Either once, you will need to either get All season tires and hope for the best or dedicated snow shoes for either of them.
