Come on guys- use your head and listen to what ForOffRoadDriving said. If you stay close to OEM sizes, you can start at what the door panel says, then adjust up or down from there to get a good comprimize between handling/wear/gas mileage for your own vehicle and driving style. I have a 99 3.0L XLT short bed, running 235/75R15 and use 32F, 28R. That works for me. Another thing to consider is load range (plys) and sidewall stiffness. Load range D tires have more plies, stiffer sidewalls and tread, and are usually run at higher pressures. Blindly following the door sticker is what happened to all those people with fully loaded Explorers, running 75 mph, hot summer weather, at 25 psi. No wonder the tires overheated and blew. A good starting point might be to ask the shop that sold or mounted your tires.
Any good technician will point you to the manufacturers specs. NEVER by the sidewall of the tire.
