WE would air up the tires a bit so that they were taller than normal farm use, and use that to get onto the center rib of the front tires, and on the center bit of the rears... for addition speed on the long road trips from the farm to the house for repairs. As long as you have a safe path and not on a dangerous road, have flashing lights, SMV, and usually an escort vehicle in the rear.. One of the roads we will no longer use as its now a major highway, full of HEAVY 75 mph traffic. Its 25 miles to the farm... HOWEVER,,, now we have 40 foot gooseneck trailers and dont have to road on long trips anymore. Did I say we have cabs and A/C on most of the tractors now?
