A few months ago, I had one of my tires plugged, because I got a nail in it. I have driven a few thousand miles onit. I am getting my rbakes changed tomorrow, and wanted to switch out my spare, which is brand new, for the plugged tire. Will there be any problems, ie. alignment, steering problems, because of the thread difference? All the tires were changed last year, and have a few thousand miles on them. Thanks.
