Range is not a static number, its dynamic. It will vary on temp, altitude, quality of gas, ethanol %, 4x4 engaged, engine temp, trans temp, your driving, type of terrain, etc.
Range is going to be between 270miles (13mpg) to 420+ (20+mpg) for a 4dr.

Did Ray Charles put them on? Sorry but they should be evenly distributed if you are going to use them, these look too small to me. Owners manual says no go.
