Interstate cruising speed
When on an Interstate with posted limits of 70-75 MPH what is your typical cruising speed with light traffic, clear & dry with miles and miles of straight road ahead?
Myself I like 64-65 mph.

Right hand lane @ 62-65 mph. Saves gas (usually gain 1-2 mpg around the 62 mark), and its safer.

65mph most of the time. I have found that my config seems to really like 68-70mph. So if the limit allows, I'll run that.

Our toad is not supposed to be pulled over 70, so never over 65.

My sweet spot with this particular set-up is 66-67 MPH. I'll often run up to 70 MPH to pass.
It has, in the past with other tow configurations been lower. (64-65 MPH)
If the speed limit is 70-75... let 'em go by.
No need for us to be anywhere that quickly.

70. Even though my tires are rated up to 75mph, the fuel penalty increases dramatically, so I may go down to 68, but don't want to create a traffic obstruction going too slow. If you're not going at least the posted speed limit in good conditions like that, you are becoming a traffic hazard, as most of the traffic will be going at least the posted limit, if not faster. I really don't like tractor trailers barreling down on me if I'm going too slow for conditions.

I like the MPG of that I get driving around 65. However I don’t like to drive more than 10mph under speed. So when traveling in 75 MPH drive about 67. When in the 80MPH of I 10 west of San Antonio I drive about 72

68 is my rigs cruising speed on freeways that will allow it. It also limits the passing of semis since most of them seem to go around this speed also.
So 68 is my max speed, I'm never in a hurry to get anywhere since retiring

65mph.
Best compromise between getting there and fighting the headwind. I can often use cruise control at this speed. Also more tire temperature friendly.
