I clearly have an alignment issue because I bought my two front tires at the same time and the edge of my driver's side tire is BALD (after reaching the tire's mileage rating) and my passenger side tire looks fairly new still.

Since my passenger tire still has a ton of wear to go, can I be cheap and buy one tire for the driver's side and get my front end aligned (i'm not rotating the back tires to the front, btw) so that my brand new driver's tire and my still pretty new passenger tire will basically wear the same.

the reason i'm being frugal is because this car is a few months from being paid off and i don't know how long i'm going to keep and i don't wanna dump money into it if i'm not keeping it. i'll let the next owner worry about having great tires if it comes to that.
