4x4 alignment? no lbc x-mac-creator="4D4F5353"

Hi gang,

 When I got new tires put on my 1990 Jeep Cherokee today, the guy said
it needs an alignment. My best friend's dad who has never owned anything
other then an International Scout 4x4(he's had lots of those) told me
one time that 4x4 never need an alignment.

 Do 4x4 need alignments? Just want to make sure the friend's Dad is
wrong and I'm not being suckered.

Thanks,

Amy
