Stock size was 235/70/16. Since the numbers are off and I'm actually going a little faster than my speedo says am I getting better mileage than I thought

According to this chart, if you were going 60mph with your old tires, you are now going 56.6mph with the new tires while the gauge is reading 60mph.

I looked at the chart, thanks. I have a tire calculator app on my phone I was using and it shows that I was going faster by 3 miles per hour. Maybe the app is wrong. So I'm getting a little mileage than I thought

I've been averaging about 300 per fill up which is netting me around 17 with 70% Highway and 30% City.

Your fuel mileage numbers will be off. When you increase your tire size, your speedometer and odometer will be registering less than what is actual. With the original tire your wheel will make a revolution at a shorter distance than the 265 tire. If your speedo says 60, your doing 63 and your mileage will be 5.5% higher too..

So blee, your saying that the chart is wrong and tarps phone app is right?

Use a gps to verify the speed & distance. Chart is definately right but I think what your doing is reading it wrong. With the 265, the speedometer is reading it 5.6% too slow. IE.. reading as 60 when in fact 63.3 MPH
