Max tire size on stock 70 Swinger

My '71 Swinger came with BFG TAs on back, size P225/70R14. These were mounted on stock 5.5" Chrysler Rallye wheels. The suspension is 100% stock. This tire fit in the rear wheelwell but could not be removed without lifting the car by the frame and letting the axle drop to its lowest point. The 60 series might help, as it's a lower profile, but for me it was the section width that caused the interference.
