I wish you luck on the bigger tires. Most of the people I know of have lost MPG by putting rubber either taller or lower than stock. Selecting tires for MPG is something the factory boys and girls do fairly well.

Your van is a 4x2, is it not? If the 235s don't fit the front wheel wells why not just go with 205s on the front and 235s on the rears. I run 225-75x16 on the front and 235-85x16 on the rear of my F-350
