My thought too, but there is also the issue of aerodynamics from being lifted, rolling resistace, rolling mass, takes more to get em goin...camojeeper said:265 smaller more rpm=less mpg in most cases
315 less rpm more mpg

What is best cruising speed on the highway for mpg that you guys see. I wanna be above 65mph
billy bobs in dallas/fort worth a good time to be had by allwnedjkdank said:Cool, just getting some opinions. Thanks guys. I'm just going to leave my 35's on for the trip, too much hastle swapping them and truck will probably look ridiculous with the leveling kit i put in and 265's anyways. Now if anybody knows some good towns with sweet country bars i can stop at on the way down please let me know! Im gonna take my time and see some of our country
hey curtis u r right on but i think you can go from 265 to285's with out any lift and get a little more mpg(safe bet) but with any lift you loose. and a gear change won't allways make it better with lift and tiresPocket said:My truck has run stock 265's, 315's, and now 325's. Going from 265's to 315's dropped fuel mileage by 2 mpg's on the highway, partly due to the lift that was put on at the same time.
Yes you are turning lower RPM's with larger tires, but it's not enough to compensate for the huge increase in drag and rolling resistance. Physics works against you every time in this case.
Was that before or after other mods?bluovaltruk01 said:When I went from a 265 to a 285 my mileage increased by about .4 Mpg
i too looked at tire rack then i took there add down to my tire shop and they matched the priceTSGS69400 said:Split the difference and get some 285's they should be just about right in between and give a good compromise. 16 " rims I assume...
Here is a good list of different D/E all terrain tires. I bought mine from here and it was way cheaper.
