I swapped out the 14 x5.5 front Rallys and the 15x10 rear Rallys for 5-slot ET-IIs, for a tremendous ride improvement.
The steel bumpers on my Barracuda weigh 30 pounds each including the brackets
Exactly ! Unsprung weight effects ride because lighter wheel/tire combos take less energy to change directions when you hit a bump .
And 1 lb of rotating mass = 4 lbs of sprung weight . Easier to get them moving .
I never did consider the front end rise scenario . Good point
