I have a 1987 D150, 2WD, 318, 2.9 gears with stock wheels and tires - 235/75/15 Wrangler TA. I would like to run chrome Steelies with baby moons for the summer and want to get more of a street rod look but am worried about messing up ride and performance. I won’t be towing or hauling heavy loads. This is my daily driver. I am thinking 245 (or 255)/60/15 BFG Radial TAs or Cooper Cobra Radial Gts. Any ideas on if these will fit ok and if so how they will affect speedo, performance, rpm at highway speed, etc?
