Anyone know what the oem tire sizes were for 1979 Oldsmobile cutlass ?

 

195/75 R 14

They are relatively small tires. On the short side and narrow.

The pics below are factory correct tire spec.

"Super Stock III 14″ wheels wear bright trim rings and are wrapped in older 195/75 Goodyear Aquatred II narrow-whitewall tires."

 

thanks. I was trying to compare tire heights
the previous owner put bigger brakes and had to up size the rims to 16 inch to fit

I’m debating on keeping brakes and getting new rims but 14-15 inch rims are in plenty supply way more choices than 16 inch

I prefer the rally style 14-15 inch type rims

I do like having big braking power but

 

x2 on the 195/75R/14, and optional was 205/75R/14. It is easier to find the 205's, currently HanKook has a decent whitewall this size and Coker just came out with 205 whitewall wherein the width of the ww is wider than the HanKook tire.

 

205/75-14 tires are 26.11" outside diameter and 8.07" section width. 215/60-16 tires would be nearly the same OD at 26.16" and slightly wider at 8.46" section width.

 

Don't forget that you can always go to Diamondback if you're looking for a white wall.

You can also get 215/60R16s in the Ironman RB12.

I put these on my 96 98 and they looked great. Although I've heard that the new RB12s have problems with the rubber chemistry and the white walls turn yellow/brown. Mine never changed color.
