Falken Wildpeak AT3W 245/70/17

I'll try to remember to get a side shot while I'm out and about.

 

Awesome, thanks. I was hoping maybe you had some taken, so I appreciate your time.

 

Hey bud good morning. You happen to get those side shots taken?

 

Everything else being the same fuel mileage will be the same. There are several factors related to tires that combine to hurt fuel mileage. Tire weight is the least important, but the only one easily shown in a chart. Other factors such as tire diameter, width, and tread type are all more important. It's just that taller, wider tires with more aggressive tread types tend to be heavier. But it ain't the weight that is causing the problem.

I've had my Tacoma 14 years and 214,000 miles. I've had 245/75/16's on it, 265/70/16's, and 265/75/16's in both E rated and P rated tires. From biggest to smallest there is only 1" difference in height, and 1/2" difference in width and all had similar mildly aggressive AT tires. Tire weight ranged between 38-53 lbs. My fuel mileage never changed.

The E rated tires do have a firmer ride, but I don't find it objectionable. There is a difference in acceleration. The truck has a little more pep when accelerating with lighter tires. It will get up to speed faster and has a little more power when merging into traffic. I'm sure it does take more power to get the heavier tire moving. But once up to speed it takes no more power, nor more gas to keep the heavier tire rolling.

 

From what I have read, reducing your rotating mass by 15lbs would significantly improve performance.

 

Sorry, never crossed my mind. If I ever have time to wash it Ill try to remember to snap a side view.
