miles per tank thread

You need a tuner to accomodate the larger tire and possibly a fuel.filter

 

Not sure where you got those tire sizes, I got [33.8 vs 31.6] for a 6.6% difference.

That makes 200mi into 213mi, but the tires are wider and heavier, which will suck down your mpg also.

325mi/26gal = 12.5mpg, 275/26=10.5mpg... 213/26=8.2mpg.

If you were only getting 12mpg before the tires, something else was wrong, but losing ~2mpg is to be expected

 

What Iowa, and AK said.
