1968 Chrysler Newport Custom Tires

I wanted to keep the stock 14" Wheels. Would 215 75 14 fit ok? Right now it has 205 70 14s on them. Here is the link. http://www.discounttiredirect.com/di...w=false&cs=215

Ok thanks but I found a page with the original tire specs. It says 8.55 - 14.
Underneath that it has:

Standard tire size:
8.55 - 14
Tire width (mm):
217
Tire sidewall factor:
80
Rim size (in):
14
Total wheel diameter (mm / in):
703 / 27.7

So wouldn't the 215 75 14 be a closer match being the original side wall translates to 80 and the width was 217? Just looking for opinions of which tire would be best. Want whatever is closest to the original. Thanks.
