MPG Impact With Bigger Tires

[TRD JON]

What is your MPG impact since installing bigger tires onto your 4th Gen Toyota Tacoma. When my truck was stock, I was averaging around 21 MPG combined and now my truck is sitting at about 17MPG per the computer. My new wheel and tire combo weighs about 90lbs in each corner and I’d say stock weight was close to 55lbs on each corner. So some significant weight has been added.

I have the hybrid. Seems like my best individual trip was around 22. And I had to baby it. This was before a lift, wheels, and tires. Just with the mentioned items, it seems to have gone down a bit. 17" wheel with 33x12.5x17. Heavier tire. My best so far (on a single trip, was just over 20 so far). There certainly seems to a be a difference. PS... my hybrid never hit 24... but we are in the middle of winter with a different blend of gas. So it does matter. Perhaps I could have gotten 25 if I tried in a different time of year. But now, we'll know, because I'm only going to make it worse lol.
