So you are looking for a specific size.
225/60/15 or 235/60/60 correct ?
They used to make V-rated stuff in those sizes, specifically 225/60/15 for 80’s and early 90’s Police and Highway Patrol car fleets. Diplomat, Mustang, Crown Vic, and Impala’s cop car of that era all used that size.
that’s a lot of fleets, lots of miles, lots of tires.
Now those are hobby cars.
Stock late 80’s Mustang 5.0 and Full size Jag’s come to mind as using 225/60/15. The first tires I bought for my 68 Barracuda with 15x7 cop rims was a used set of Yokohama AVS off a 4-door Jaguar
