Yep. G70x15s on a 15x6, biggest B tires till 1970. I think Hemis had F70x15s, certainly did in 69, I think in 68 too.

I wonder what size the 9.15 X 15 tires on a 1968 Imperial would be in the newer ways of measuring.

Most tires were 14 " back then unless the car had factory disc brakes.
When they were available depends on the brand/model.
Firestone Wide Oval was first starting in 67 and later Goodyear Polyglas in 69.
Closest modern size conversion of the 915-15 is a 235/75-15.
The replacement size for the 915 was the L78-15 back then.

You may be onto something with the Imperial. The code book shows the option for ‘68. I really like the G70 size vs the F70
I’ve run G70s for decades, my one departure from stock original. Original owner of my GTX did the same for a year when he replaced the factory F70s.
What about 68 300s and the like.
Back in the 90s, the '62 Imperial that was my daily driver came with an L78-15 spare in the trunk, with 235/75-15s on the ground. After using the ancient spare one time without a failure, I changed it out for a 235/75-15.
here's the OE tire sticker in the trunk
of my 68 RR RM23 383/tf St Louis Build, with 14" Chrome Road Wheels 'originally'
Uniroyal F-70-14 or 7.75-14 IIRC white raised letter
