So I can run 285/75/16's. Would you guys suggest Tundra coils up front with a space and 890's in the back. Or 881's in the front with a spacer, and 890's in the back. I also work at a plant farm providing mulch and heavy trees to customers. EVERY NOW AND THEN towing maybe 800lbs max. 890's or 891's in the back, and tundra's or 881's (both would probably be with spacers)??? I understand that both can clear 33"s.
