35's on a dually...will I loose MPG??

Haggs2002 · 10-23-2009, 09:36 PM

Just like the title says, if I throw 35's on my dually will I see a big drop in MPG? I hav 235/85R16's on there now, and would put 315/75R16's on there. Most of driving is highway and the rear axle is a 4:10. Anyone done this and have reports? Whaddya all think?

I run 35's on my early 04 with 4:10's getting about the same a 265's in town but getting 1 to 2 mpg better on the road. With the 35's i turn around 2,000rpm down the road with the 265's i'd turn around 2400 or so.
