When I bought my Dart GT it had a "temporary use" spare tire from a Neon (5 on 100mm bolt circle). Nope!!
I found and bought another 14" X 5 1/2" sbp Rallye wheel (had to be a Rallye to clear the SSBC front disc brakes) and put the same size tire I'm currently running on the rear, to protect the 8 3/4" sure-grip.
Since I run different sized tires (front vs. rear), is there a +/- tolerance to prevent damage to the 8 3/4" sure-grip?
