I have attached a photo of the sidewall of my truck tire. It is made for either single or dual wheels. However, notice that it is de-rated by 224 lbs per tire when used in a dual configuration. The unfortunate side of the P tire is you never know what the de-rating for duals would be since I am sure there is not a chart for that. Lets make a guess at it: 3416/3640=.938 or about a 6.2% reduction per tire. For the truck tires. Lets take it to 7% for the P tires the two tires have a load rating of 2800 lbs or 1400 lbs each. If we are guessing correctly reducing the rating of each by 7% gets us a dual rating of 1302 lbs each or a combined rating of 2604 lbs almost a 200 lb drop per side. Just something to think about. My personal preference is to have as little rear end squirm or slew as possible; if there is too much it just feels squirrely and on a long trip that will get tiresome fast.
