    I am perusing truck tire sales and I was set on getting LT tires but due to the heavier weight I am now reconsidering my choice. I know my MPG will suffer and I want to know how much it will suffer.

    The Rugged fails have not let me down yet... but I sure as hell won't be buying them as replacements. I drive 99.9% street and highway and I was doing about five (5) expedition off-road trips a year. The ideal solution would be to have two sets of wheels one with a touring tire and the other with a nice off-road tire. But I'm not there yet and I'll have to make do with one set of wheels for all purposes.

    So my question is for those of you that have LT tires, how did it affect your MPG?

    Thanks

    They duratrac's come in a c load range in the 265/75/16 size. This would be a good option for you. They are only 45lbs per tire verses the rugged fails 37lbs. Shouldn't notice a big difference in fuel economy from that. Maybe 1 mpg if that. Some of those e load bfg's are almost 60 lbs per tire! :eek: But they are tough for sure.

    Thanks.

    Right. I think "C" range is where it's at. I was looking at "E" range but I think that's overkill and would be too costly in the long run for my MGP.

    Yes. I want 265/75/r16. Thanks. for the weight comparison, that helps lots.

    weight of bridgestone duelers factory 265/65r17 is 38lb duratracs in the c rating run at 44lb for 265/70r17. I am surprised to see a 1 or 2 mpg loss over 6lb more tire weight. Sad these are the tires I want.

    I upped it to 265/75, D range.....i have noticed maybe a 1-2 mpg loss, however, i cant tell if its winter gas or not becasue i swapped them right as the season was changing. They ride nice, no power loss either

    I average 200 miles per tank on my LT315/75R16's and 4.56 gears with 56k on the odometer. Don't ask what I get when towing lol
