Just bought a 1998 Wrangler TJ and it does not have a spare tire. It has, almost new, 32x11.5x15 Goodyear Wrangler MT/R tires and Mickey Thompson wheels. I'd really like to have a matching tire/wheel for my spare - but I don't want to pay for new. What do you think the chances are of me finding that set used from someone/somewhere? Slim to none?
