Well...I did a ton of research myself over the past few weeks.
I just purchased the Nitto NT420s in 255/55/18.
$556 to my front door.
Out of all the tires in this size, at www.discounttiredirect.com, these had the best overall rating among consumers within an affordable price range. That said enough for me.
Of course, this tire is different than most...design wise, but I look more for function than glamor. I am a bit nervous on the overall diameter, but if need be, Ill keep my golf clubs in the rear to help things out!
They are NOT a directional tire...according to NITTO.com which means they can be rotated all over the place.
Here they are on a VW Toureg (sp?)
