Calvert Springs; not happy
Update:
All installed. Clearly, as stated above, the 255 tire allows 4.5 inches clearance. 275 drag radials over 3.5 inches. I'm thinking 2.5 inch lowering block, however, the opinions are diverse. Some say absolutely not, others are running them with the monos with zero problems.
Can you still use shims to adjust pinion angle if using lowering blocks?
