It depends on whether you have a front or rear wheel drive car,
toe-out for front wheel drive and toe-in for rear wheel drive,
generally speaking anyway. Just because I can't think of a car with
something quite different doesn't mean that it isn't the case, just
that I can't think of it.:-))

OK, just to add more fuel to the fire. As I said I had 20 years of doing car
alignments with repete customers so I got many chances to see "long term"
results. If a car "needs" some sort of "preset" (toe in or toe out) to
compensate for what will happen when it is driven then experience has tought me
that something is generally loose that needs fixing first. Customers want two
things; First they want the car to go down the road straight when they take
their hands off the wheel. (don't ask me why the hell they are taking their
hands off the wheel, I couldn't figure that one out). They also want their
tires to wear evenly. End of story. Tried many manufacturer's recommendations
over the years but zero toe in always proved the best to keep them happy and
coming back.
The inner side of the right tire always seems to wear more on my RV. Don't know
why and don't care. Rotating them and flipping them on the wheels each odd year
gets me 200 hours out of a set. Can't complain; cheap tires and it's the most
stable tail dragger I've ever landed. (my tail wheel springs are snug and the
wheel is the old non-pivoting type. couldn't tell you if that's good or bad)
