    I think the stock tire on my 72 Skylark is 205/75/14? Will fit that car that is a slightly wider tire. The current ones look silly they are so small looking.

    Plethora of different sizes you can run. If you go to 15" rims 245/60r15 is popular. Otherwise in a 14" you can go to 225/70r14. It'll be almost an inch wider (8.1" to 8.9") with minimal change in height (26.1" to 26.4").

    The factory 14 wheel offset is not appealing either. Later g body Rallye wheels do stick out more and would look good with the tire sizes mentioned

    You can run a 245/60R15 on the front with no issues. And a 275/60R15 on the rear. Or you can swing for the fences and put a 325/50R15 on the back on a 15x10 wheel.

    I seriously doubt you would have any issue running 225/70r14 on your current rim. When i ran my tire shop for 11 years, we upsized ppl all the time when they wanted. The rule of thumb was always anything under 10% wider and under 3% taller was usually good to go with no mods. Going to a 225/70 will give you a bigger contact path along with being more visually appealing. Tires in that size aren't to pricey, Cooper Cobras run $108/tire on Tire Rack & $83/tire on Walmart online.

    225R70x14 on 14x6" rims fit with no problem. Had them on my '72 GS for a couple years the replaced with 15x7 rallyes + 245R60x15 BFG T/A radials.
