- are you sure this tire was properly inflated?
- the august issue of C/D has an article about compact spares.
- get this: the corvette LT1 ran 0-60 only 0.1 sec slower (in 5.2 sec) with the
- compact spare on one of the rear wheels. here are the numbers:
- compact-spare 0-60, 70-0, ft. emergency double roadholding, g
- location sec lane change, mph
- none 5.1 165 62.9 .92
- front 174 62.2 .84
- rear 5.2 174 59.6 .90
-
- i'd venture a guess that the vette was considerably harder on its
- compact spare during the 0-60 (300 bhp!) and skidpad runs (tires often start
- chunking) than your car was cruising along at 50 mph. the article says
- that during the acceleration runs, the compact spare left a long thin
- stripe of rubber on the pavement (the traction control was turned off).
- and besides, a bunch of guys from uniroyal did the One Lap of America
- (an 8000+ mile rally) with a compact spare on the rear left wheel.
-
- wow. those little rubber donuts are pretty tough.
