I know it has been discussed before, but I am going to need new tires in the next 6 - 12 months. I have 410 gears and drive 25 miles to work every day and 25 miles home. If i keep my speeds at 60 or less I average 17 mpg. If I go 65 - 70 my mpg drops to 13.75 - 14.5. Tire change option only, I am not changing gears. I would like to, but its not in my budget or time frame right now. especially time frame, I work with my truck. So with that being said, What would be my best option. 255 85 16 or 235 85 16 or 285 75 16. 235 and 285 give me the most options in tires, but the 255 is tall and skinnier than the 285 for less drag. I currently run 235s. I am going to buy new tires anyway just looking for some educated opinions. Emphasis on educated. Thanks guys, Have a blessed evening.
