You make life complicated - do the same calculation you did for one mile and
divide the result by 5. The reasons I usually use a longer stretch are a.
there is one just south of town here on the interstate and b. when you
drive an 87 Comanche with over 180k on the clock at 6500' elevation and a
5-spd gearbox in front of 307's speed control is a tad hit or miss.<G>.
Turns out, my result with 235/75R15's was exactly 7% slow - enough to get
you a ticket in most states where the speed limit is 75. Besides, I was
already bored with the trip and still hadn't reached to Colorado border
when the destination was South Texas.
As an aside, the highest mileage I ever got for long trips in that Comanche
was 27 mpg. Colorado Springs -> Abilene, TX using 5th gear (2250 RPM) and a
40 kt tail wind all the way. Believe it or not, the second highest was 25.5
mpg CS to Billing, MT into a 35 kt wind running 4th gear and 2700 RPM all
the way - go figure.

Well, back from the dealership. I found out my speedo was actually
off approximately 6 mph. To my surprise, they do not change out the
actual speedo gear anymore. It is all done by changing the tire size
in the vehicle's computer. I also asked them to turn my steering from
side to side in full wheel lock while it was there to see if I had any
rubbing with the new bigger tires. According to them, I did not have
any at all. Again to my surprise. Well, the surprises kept
coming....I got ready to pick up my Jeep, they handed me my keys and a
copy of the work performed and said I was "all set". So I went to the
cashier to find out what I owed, and she told me "nothing". So, I
saved myselft approximately $40.00 yesterday.
Here's the kicker -- I took my car to a different dealership other
than where I bought it because it was easier (and closer) for me when
I got out of work. Plus they have evening hours for service. The
dealership that I bought it from was going to charge me $40.00 to
recalibrate the speedo. How do you like that? You would think it
would have been the other way around (the place where I bought it
wouldn't have charged me). I was literally in and out in 15 minutes.

Well, back from the dealership. I found out my speedo was actually
off approximately 6 mph. To my surprise, they do not change out the
actual speedo gear anymore. It is all done by changing the tire size
in the vehicle's computer. I also asked them to turn my steering from
side to side in full wheel lock while it was there to see if I had any
rubbing with the new bigger tires. According to them, I did not have
any at all. Again to my surprise. Well, the surprises kept
coming....I got ready to pick up my Jeep, they handed me my keys and a
copy of the work performed and said I was "all set". So I went to the
cashier to find out what I owed, and she told me "nothing". So, I
saved myselft approximately $40.00 yesterday.
Here's the kicker -- I took my car to a different dealership other
than where I bought it because it was easier (and closer) for me when
I got out of work. Plus they have evening hours for service. The
dealership that I bought it from was going to charge me $40.00 to
recalibrate the speedo. How do you like that? You would think it
would have been the other way around (the place where I bought it
wouldn't have charged me). I was literally in and out in 15 minutes.
