Do your 215/75r15 tire sidewalls rub your tie rod ends? I have old 225/75r15 on my 37 & they really rub. These are just spare tires to roll the truck around. Also, how do they look height wise?
215/75-15's do not rub anything on my '52. Your '37 could be an entirely different story and was probably designed for a skinnier tire than an AD truck (although I don't know that for sure). If you want to see how they look height-wise take a look at my pics earlier in thread.
The black wheels are 15's.
The red wheels are 16's.
