Editorial Comment:

Usually, most cars have the same tires on both the front and the rear, and I'm not aware of any special needs of the 89 Corvette, so unless you've been doing some special mods it shouldn't make a great deal of difference, providing the tires of of the same amount of wear.

If you have tires which have different amounts of wear you generally want to have two tires with the same amount of wear matched on the same axle, and the tires with the best tread on the front to provide you with the greatest steering control.

Even directional tires can be mounted on either side of the car, providing the tire rotates in the direction of the arrows. If, the arrows are pointing in the wrong direction, you need to take them off the rim, flip the tire over, mount and re-balance it, then you can install it so that it will rotate in the correct direction.

The usual effect of putting a directional tire on "backwards" is that you will lose the water-dispersing characteristics of the tire which may affect handling in wet driving conditions. The tread will not wear more quickly, nor will you have any major issues apart from the wet driving. This is something to keep in mind if you have a directional tire as a spare and need to change it because of a flat.
