Someone will want to argue with this too but I've heard similar remarks from tire dealer as what oldblu49 posted. Just not a good idea on those little narrow wheels. I have to believe that the tire folks know more about this than I do and I still maintain that LT's are too heavily made for a 51' 3100. The main reason I think you guys who are using them is exactly what I first stated..doesn't seem to be any other choices if your going to keep stock wheels. It would be OK on a proper width wheel but I don't know what dbone has so I must assume a stock wheel. Anyway, here is what my 285/15R-70 look like on 15" A/R aluminum wheels.
