widest tire on 6 inch steelie?

It wasn't safe but I didn't know they were that narrow until I dismounted the tires.

6.5" steelie with a 29.5x12.50x15 M/T Sportsman Pro. I always wondered why the car would get a little wobbley at high speeds. Heck I even took the car to the strip a few times.

I know this doesn't really answer your question but thought I would share anyway.
