Another argument is why rotate at all?
On my 86 Chevy pickup, I never rotated tires. The OEM Uniroyals went 48K miles
with
even wear, and then I put 2 sets of Michelins on it that each went 80K miles
with even
wear. Then I put a set of cheapy tires on it now that the truck is getting a
little
worn at 230K miles...but I'm still not rotating tires on it...
Our technician at work drove a roughly equivalent era F*rd pickup, he rotated
tires
religiously, and that truck still ate tires at more than twice my rate.
I do rotate tires on my wife's Jeep Wrangler and any front wheel drive car I've
had ate
front tires as well.
