They hook up really well. If u notice in the videos the side walls are wrinkling. I didn't know it on this ride but I had 17 lbs in the front found out after I got home. Got about 7 pounds in the rear
The tires are 18.4 x 16.1 on MRW 16 inch wheels. I got them from a tractor junk yard. I cut every other row of lugs out except for the very center lug on the back tires
