Mt truck is missing the spare tire, what size spare tire and what type of rim did these trucks come with? Can I go to the junk yard and get a spare rim from an S-10 or Sonoma?
A regular 4x4 S-truck wheel will fit on the truck. Since it's AWD, you need to make sure the overall circumference of the spare is the same as the regular wheels though. Otherwise you'll be trying to turn drivetrain parts at a different speed from each end, which they don't like...
