Jt..."it wouldn't make any difference from a practical standpoint" ..I hear what you are saying from a visual point of view if that's why you would buy an SUV. I can't speak for Mike but for me....lFrom a practical point of view, everything that real SuVs are made for, suffers from exceptionally low profile tires.
Off roading, heavy towing, rough roads, snow/ mud traction etc, all that true SuVs are designed for, are better performed on standard rim tires then the aftermarket low profiles. I would NEVER own an SUV for looks alone. If they can't do what they were designed to do as well with after market tires, why bother. I would have no use for them.
But jt , you are absolutely right. Many SUVs are just fat mall station wagons in use and their owners impress each other with 20 plus inch rims.
