Might need someone to look at a truck I'm considering around Grant's pass

The guy in center point with the w250 said that it had 3 great (new?) tires and 1 "bad".
Maybe the location of a pick n pull nearby where i could pick up a couple of mounted spares to toss in the bed for the ride home?
Also that it will be needing exhaust but not to what extent. If it was obnoxious enough to not be able to stand it for the ride home "and then deal with" once here, recommendations for a good exhaust shop that could either fix it or replace it reasonably would also be appreciated. (I can't bend pipe alongside the road haha)
