Default DS Rear Slick Tire rub issue

Removed rear slicks to replace for new season as existing ones quite old despite only having about 40 passes on them.

DS tire has rubbed the inner fender (shiny spots in 1st pic) and even the frame in front of the tire. While I assume its ocurring on the launch and due to running too low of tire pressure, I would have expected the issue to show on the PS but there is no rub marks on that side.

65 GTO dedicated drag car (estimate 11.90 area in qtr mile, 7.60 actual 1/8 mile time)
3500 lb with driver
Moser 9" rear, boxed lower control arms, adjustable uppers, 70/30 shocks, stock springs, still running an air bag on PS only at 15 lbs
Hoosier 10" x 26 drag slicks, bias ply at 14 psi
Transbrake launch at 4,000 rpm

Is it just a tire pressure issue? If so why on the DS and not PS? Lack of preload on DS?

Car sticks good (1.65 60 ft) but tires do crinkle quite a bit

Thanks for any thoughts on why DS and not PS and any recommendations
