Yea, then I run into the problems of having them mounted and all that. My final numbers look like:

Tirerack after shipping: $489 + $60 for mounting/rotation = $549 driving away without: Free flat repair, free rotation, free snow changeover

My local Town Fair Tire said as close as they could come to my total price was $567, which I will gladly pay. What's $18 when a tire rotation would cost me more than that?
