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

fit, yes, but they are 1 size smaller than stock.

oh, when I bought the car it had 205 70 14 on it. sO THE STOCK SIZE IS 225 70 14?

right. i ran 205s on my sixty eight but the speedo was off about 8mph or so.

ok here is something i found the 215 75 14 is a little taller than the 225 70 14.

Original tire
Sidewall: 6.20 in
Radius: 13.20 in
Diameter: 26.40 in
Circumf: 82.94 in
Revs/mile: 763.90
New Tire
Sidewall: 6.35 in
Radius: 13.35 in
Diameter: 26.70 in
Circumf: 83.87 in
Revs/mile: 755.45

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.
