QUESTION: I am looking at purchasing a JK rubicon and doing the same Teraflex 2.5" BB and Toyo tire swap. With this, how did it impact your gas mileage. Should I expect a mile or two less per gallon or the same that I am getting now. Also do I need to purchase a computer recalculator? Chuck

ANSWER: We didn't notice much difference in gas mileage since the tire size percentage change is so small. The JK Rubicon is equipped with 32" tires from Jeep and the Toyo's we used measure out to about 34". One thing to consider is the Rubicon is equipped with 4.10 gears. Most other JK models have higher ratios which will affect gas mileage more with an increase in tire size. Regarding the computer..you should not need any changes to the computer with the tire size increase.

Different Tire Size Front and Back

Question: I just put tires on the back end of my 2006 liberty. I realized after I noticed the ESP light come on that the dealer put the wrong size on the back. I have 225/75 on the front, they put 225/70 on. I had them changed to 225/75 s is that going to be alright? Dwayne

Answer: If the light went off everything should be fine. As long as you didn't run in 4WD on the street for any extended time. Off road 4WD use should have been fine since the tire size wasn't drastically different.
