As for the circumference, an adjustment to the SG may be necessary -- not a big deal. I usually have mine set to the most pessimistic settings so I try harder. The displayed FE prompts additional effort if it's perceived as low. The trick is to disregard the setting and shoot for that higher goal. Hopefully, I'll have 2 record tanks through this and lower cruise speed.

Let us know how the new tires work out!

Thanks for reminding me. I have adjusted the SG to show a +2% speed increase on the MPH, so it is accurate for these tires.

I will be doing a GPS adjustment in the next few weeks, so I will add the results to the thread.
