Thanks Al and FM, I have the same rollout as these are , but will be on the wide rim so I assume I will lose a bit going up two inch over measured rim width? If they will hook as well as the 2078 Goodyears, (33x15x15 Stiff) it ought to pick up a few hundredths in ET. 16 lbs lighter, plus less drag, plus more air pressure, I assume? I have never tried anything on this car except a 14.5x15 radial drag slick, which almost crashed my car.
