wore out tires they can guess at setting but with new tire jeep wil be setting like it should they could adjust it with or with out its just better to set alignment with new tires so why not just wait and do both or get new tires one week get alignment the next
you can. Why not. Front end alignment on today's car's is simply a toe in or toe out. A lot of cars, its simply just a very little toe in. Check the tires yourself before you go this route, I was doing it myself last week and found one of my tires had a huge break in it and I got myself some new tires.
you can..the alignment is done by the front end and wheels...doesnt matter if tires are good/bad...i just did same...45 dollar alignment on 99 s 10 and rotated tires...all good.
