Never even was thinking of the brakes. The brakes lock up nicely with the original tires now. Not surprising considering I have went from a grain box to a flat deck. I’m guessing the box held in the area of 150 - 200 bushels. 12000 lbs lighter should make a noticeable improvement. That being said as I remember loaded grain trucks never could stop. Of course unless loaded in the field and then one could put your head into the windshield just by letting off the throttle .... The increased size of the wheels would be multiplied drastically in stoping distance. Not to mention stress on the brake components. And not in a good way. By changing the size I have come to the conclusion that this will change the steer and brake geometry. A can of worms I do not need to open. Back to the hunt for the original size. Thanks
