After just over 2600 miles so far this late fall and winter pulling the teardrop..I have found some cheap Chinese tires are very picky about tire pressure. I have to run 2/3 max pressure to get ANY kind of mileage out of them. Changed one out at 1700 miles with the center wore almost out even with watching pressures. I just got back from a run down to Holly Beach, La. last week (before Mardi Gras and spring Break folks were there). I slept like a baby in it with the surf 150 feet away. I got an average of 24.8 mpg going down...23.8mpg coming back thru Tx and up to Texarkana on way better roads with 65-70 mph speed limits on Tx highways...and from Texarkana back up to my home I got 25.4mpg average. Most driving was done from 55 to 65 mph max for mileage. I can't explain the Tx mileage difference...maybe their roads are good and fairly smooth but sticky? lol
I might put quite a bit more miles in it this spring and summer...good Lord willin and the crick don't rise.
