Hello, I've got an '87 Cutlass Ciera that I want to get rolling and it's needing tires. Looking at the tires and I get four different sizes. Looked in the manual and it said to see the door jam, looked in there and the cards are just about painted over. Fantastic. Online I see 195/75 and 185/75, I'm assuming that it's 195/75, as that's the tire on the front driver wheel, which I'm guessing is the one connected to the speedometer and odometer. Is that correct?

 

The OEM tires were 185/75-14 except on cars with the FE3 suspension package. Those got 215/60-14.
