5 lbs of Weight Difference per Corner

What you're looking for is, "Moment of Inertia" which is basically how hard is it to turn the accelerate/decelerate the wheel. What we don't know is the distance of the mass from the radius but I think you'll find that in this scenario, it won't really matter.

Here is a general video on this. https://www.khanacademy.org/science...m/torque-tutorial/v/more-on-moment-of-inertia

 

You've had some time with the new setup. Any change worth reporting?

 

yes, i'd love an update. personally, I lost ~2mpg. But I lifted my truck, went to a 33" tire and went from an SL to an E rated tire.

 

I think I lost about the same when I lifted and went with a 32" tire. Considering going to 33" when these wear out.

...but I didn't correct for actual distance traveled. The reason for that, my odometer always showed I was going faster than my GPS or radar before the 32" tires, so I don't think the mileage on the stock tire size was accurate. Now, they match, so I'm pretty sure I'm getting "real world" numbers from the ODO.

 

If you go with an 1" taller tire what difference are you seeing in performance. Mainly torque/lag? I have searched on here but probably not using the right wording.

 

5 lbs per corner is nothing. The tires on my Tacoma are 15 lbs each heavier than what came from the factory. Fuel mileage and performance is exactly the same as before. Going to a taller tire effectively changes your axle ratio. Dramatic changes in tire size will make dramatic changes to fuel mileage and performance. Wider tires, and tires with aggressive tread increase rolling resistance and will have an effect on fuel mileage. Going to a taller and wider tire will increase tire weight, but it is not the weight that is the problem.

 

I didn't just lift and go with a 1" larger tire. I've also added skids, bumper, sliders, etc.

FWIW, I went with the factory width tire (265/70 as opposed to the 265/65) just a little taller. The lift dropped me about .5 mpg overall and the tires went down I think another 1-2mpg. It's been a while, so I don't recall.

This is debatable. I'm not trying to start a debate, but I read varying opinions all the time. I brought this thread back up because I wanted to hear if @bludweiaer experienced a difference. But, for the reason that you mentioned above, I hope to regear as funds allow.
