Not sure those are L60's they look like radials, but a lot depends on backspacing - or rolling the lip 

  I'll try to dig up a pic of my first Nova with the L60-15's, they were really square and made a major racket when the lips came down on them.  
One night while racing 5 wide on the Roosevelt Blvd in Philadelphia, I hit a low spot on the road.  The lip came down, sliced the bulge of the sidewall, and left a strip rubber dangling off of the tire.  That stupid strip flailed around and slapped rubber streaks all over my new cortez silver paint job 

  Then again, I could have stopped
