4.88's vs 4.10's on 35 MTRK MPG change
Ok this is GPS mileage. On my 04 auto rubicon I ran Nitto terra 33's/4.10 and was averaging about 16 on the Hwy.
Then I put on the 35's and it dropped to 14.3 on the trip out to regear. Coming home the new GPS reading was 10% from the speedo, 60=66 mph.
I ran 94.6 GPS miles @ 70 to 75 mph and used 5.36 gallons for a MPG of 17.6. That is a 3.3 mpg increase for the gear change on just hwy only. I did not expect that big of a bump or to be better than the 33/4.10 combo.
