GX550 Real World MPG (15 Viewers)

[Counselor2025]

I just checked my mileage after changing tires to the KO3 275/70/18 E tires. I was averaging 18.5 mpg for mixed driving. After accounting for the larger diameter tire, I lost about 3/4 mpg. Considering the increased stability with the new tires and better off-road performance, I feel pretty good with the results. The tradeoff is well worth it.
