    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?

    I’m running 31/10.5/15s on my truck and they rub a bit. 255s would be the way to go, the 31s rub if you hit a speed bump but other than that they fit good. Speedo would be a bit off if your going 55 it’s probably going 59. It would keep rpms at highway speed low and would give more torque.

    That’s what it looks like with the 31’s

    Thanks! Your truck look great! Any problem with passenger rated tires on light truck?

    If it’s on the front it’s probably not a problem but if it’s on the back and your going to haul stuff or tow a trailer they might be a problem
