I must say I never bothered to check the air in my spare tire when I put my Insight on the road, so I never realized how trick the spares are in these cars!
14 x 4 inches, and the Sartorius says it weighs in at 15.1501 pounds with the tire on it. Granted the wheel and tire are for temporary use only, but I think I will still make them the next thing I try to scrounge up a set of 4 of. For off-highway, non public road use only of course! I wonder what the narrowest, tallest 14 inch tire still produced is?
