whats the point in having brand new tires installed with a jeep that's gonna be re-aligned after the fact? That would mean the tires are beginning their life on a vehicle thats out of alignment....though a couple hundred miles probably wouldnt make a huge difference, just makes more sense to me to get the alignment back to spec again, then put the new tires on. Does that make sense?
No it doesn't make sense.
The tires are going to affect the alignment in a negative way (on an incredibly small scale, but it will still skew the alignment slightly), and if you are about to get a free alignment it will be better to install the tires first. Then you will end up with the best possible situation.
This is all that much more applicable if you want to upgrade to a larger tire.
