* Check your E250's sticker: Look for the sticker on the driver's side doorjamb or the glove box. This sticker will specify the recommended tire size and load range. This is the most crucial information.
* Load Range D is often sufficient but not always: A Load Range D tire is often suitable for many E250 models, but if your van is heavily loaded or used for towing, it might not provide enough load capacity. Heavier configurations may require Load Range E tires.
* Don't just look at the tire size: Matching the tire size (e.g., 225/75R16) is important, but the load range is equally crucial. A tire might be the correct size, but a lower load range (like D instead of E) will be insufficient for carrying the weight your E250 is designed for. Overloading tires is incredibly dangerous.
In short: You *must* check your E250's sticker to determine the correct tire size and load range. Using the wrong load range can lead to tire failure, accidents, and void your warranty. If you are unsure, consult a tire professional or your Ford dealership.
