Will it fit? L60-15 Polyglas GT on 15x8 steel 4" BS

Not sure about L-60 15's but heres a pic of L-60 14' on a Crager ss 14x 8 wheel.
Definitely a little too wide as they would hit the wheel lip . Air shocks helped though as I raised the car to clear.

Do you remember what the backspace was on that 14x8? Looks less than 4"
