I would suggest an average speed of 60 mph. What's the hurry?

On interstate highways we average 60 mph and find it both a comfortable and fuel efficient speed. Since we typically limit a days travel to 350 miles max keeping at 60 MPH has little impact on total travel time. Furthermore, should we spot something interesting, like a Cabelas, Bass Pro, or God forbid an antique shop we have time to stop.

If memory serves I think the optimal highway speed for fuel efficiency is 55 MPH. I believe the following MPG decreases over 55 MPH are close to accurate:
  • 60 MPH - 3%
  • 65 MPH - 8%
  • 70 MPH - 17%

The biggest reason (I think) to limit speed to 65MPH is because that's the max speed for ST tires. A couple of manufacturers state that you can increase 10MPH if you increase the cold pressure by 10PSI. Other manufacturers are "strangely silent" and say nothing about speeds over 65. LT tires have a different max speed, however, if you're running "Chinese maypops" it probably would be wise not to push the envelope too far by towing faster than they recommend.....

Like others have said, towing 65 vs 60 in a 7 hour day is only 35 miles further down the road.... Some may think that's critical, but for this "old retired fart" I've gone enough 35 miles further in my life without feeling the need to do it any more....

60-65 and relaxed, kinda watching the billboards to find something interesting to "take another break" is a much more relaxing trip. We'll get "there" sooner or later, no need to push it against the "weakest link's" max speed.....

After many years of driving commercial vehicles in Europe and Canada I feel that 100 Kilometers per hour 63 MPH is good for fuel economy, good for the vehicle and you make good time. Just my thoughts after over a million miles of experience

I vary depending on weather. Hot days on dark blacktop road I drop to 60. on cool days or a light, gray concrete road I'll go 65. Not sure how much difference it makes in the tires temps, but it makes a difference in my peace of mind. As stated before, it doesn't make a lot of difference in the end result for distance traveled. I have been passed many, many times by people going 70 plus. Can't tell you how many times I have re-passed them while they are pulled over changing a tire. As for fuel economy, I haven't noticed a difference between 60 and 65.

I keep it to a max of 65 - that way the speed differential with trucks in a 70 limit is not too big.

One thing I learned a couple of years ago is that, in many states, a vehicle towing a trailer is subject to the same speed and lane restrictions as a truck! I know a lot of drivers ignore this, but I stick to it and feel a lot safer not trying to pass in the left lane if it is restricted, and keeping my speed to that similar to most trucks.

Even though we aren't retired, we still keep it at 60-65. The tires are the biggest reason for us also, why borrow trouble? Besides it's vacation time, sit back & enjoy the ride.

Post #8 applies to Oregon, the truck speed law is about a page long. But, main point ANY vehicle or combo ie (pickup with RV) that has it's current weight 10,000 lbs plus is to follow max. speed for trucks, that is 55 in Oregon. That weight is not based on the vehicle GVWR but real phsycial weight. Passenger vehicles and combos under 10,000 are allowed the other max. speeds which can be 60, 65, 70. Any vehicle pulling any trailer is not allowed to use the left lane unless passing slower trafiic.

A lot has been said on this speed topic and I agree on them all. I would add that I use the speed control while on the I-state. 60 is the comfortable speed for me, so I just set it and forget it. By doing so, it also keeps my speed from creeping up to 65 or more.
