Keene Dodge Chrysler Jeep Ram

i purchased a 2011 jeep and it came with full size spare. spare tire is not the same tires that came with it. I have argued with every manager in there except finance. i have argued with the owner regarding this tire. he is blaming chrysler. called chrysler and they have a case man working on it. well i am going to Better Business Bureau on friday. i am have documents cert from other dealerships and pictures regarding that chrysler doesn't not send kumco tires for spares when they put michelins on there. if the dealership put michelins on there they could said instead of lieing and say that chrysler did it. As everyone knows you can't use that tire even for temporary use. Another thing is there is only person that knows in detail about the 2011 jeeps. i had to get more manuals from chrysler regarding changing stuff on the media center.
