On the street, its pretty much entirely a tire wear issue, particularly if you're running stiffer suspension than stock and big tires. Some guys deviate to get fender clearance, but you've got a widebody, right?

On the track, its another issue entirely and it depends on what your tires "like".

Toe, on the other hand, is instantly noticeable. In on the street, neutral or out on a track/ax car. With big tires, neutral or out on the street really increases driver workload.
