How much did your mpg change? GY Duratrac

Any of you guys running 265/70/17 GY Duratrac? on the stock sport wheel? What do you guys get fuel mileage wise?

 

I don't see it being to much, I'm running 285/75/16's and still get 19-20 highway with a light foot.

 

I got a 2MPG loss on my Duratracs. Although they were great tires, I ended up switching to Michelin LTX AT2s because they were a lower Load range, 64lbs lighter, longer tread wear, better warranty, and better wet/dry performance on the street. So far the Michelins have been the best all around performing tire I've run.

 

I just bought a set of 265/70/17 load range E duratracs and my MPG dropped ~3.5mpg. I was getting average of 17-17.5, now I'm getting just about 14

 

I apologize, load range C, not E

 

Sorry, late post. Are you 4x4?

 

It should be noted that new tires have a much higher initial rolling resistance than worn tires and will factor significantly into the efficiency of the newer tire.
