I have seen a much more significant loss in mpg. My avg mpg with stock tires for daily driving was 23mpg, I now avg about 20mpg. For highway driving at 65 mph on a specific commute in cruise I would get 29mpg, I now get 27mpg. Now for the bigger hit- on higher speed driving (75-80mph) I would avg 26-27mpg visiting my family, that is now 22-23mpg. I understand that the reason for the loss in mpg is some drag and more effort and this is certainly seen and enhanced with higher speed driving.
I want to add that these numbers are calculated after accounting for the difference in the speedo. The display reads out lower. 19.5 city, 25.5 on my highway commute and 21-22 on higher speed freeway driving.
Thanks to you both for the quick response.
It seems the average is roughly a 2 MPG loss, except if you increase speed, there by pushing more air and creating greater drag. Makes sense.
Anyone with CRD try the BFG AT KO's? I ran them on my 94 ZJ limited and they were not bad either and maybe a bit lighter than the duratracs. I assume if some weight could be shed there is less mass to push resulting in less effort and saving some fuel.
Can you guys tell me who have the qudra lift if the tires in this size will rub in the aerodynamic or sport mode. I have a 2013 v8 Summit with OR II and stock 18s. From your photos the Goodyears looks good. The stock OEM look bad and terrible in the snow. Thanks
What are "both ways" of turning off the air suspension that wraab mentioned? I just got a '14 JGC Overland Eco diesel with ORAII and am planning on having Americas tire put on this set of 275/65/18 Duratracs. Thanks
I put the Duratracs on and have about 1000 miles on them. They're pretty much brand new. I'm selling my Duratracs. I love the tires but my wife drives the car most of the time and doesn't want them on. I'm in MD, if anyone is interested, pm me.
Hi, I am about to order these tires and then I noticed that the LT's and the P's are both available in 275/65R18. To make sure I get the ones that fit and do not rub, are we talking about the P or LT sized tires that fit without rubbing?
