My second car (1994 TBird 4.6) has the typical mini-donut spare tire in the trunk and I am not a huge fan of putting an almost motorcycle tire on my near 4,000 lbs. MN12 if I had a flat. I was wondering if anyone was lucky enough to get a normal size spare tire with their car and what size it is. Also has anyone else put in a 215\70\15R spare tire in place of the donut in the trunk and had no issues? I was hoping on using a factory fan-blade rim. Thanks in advance!
