Being a retired truck driver who has lots of experience driving trucks and trailers with super singles I can tell you a few things from experience. We had a driver in our company yard loaded to the max (102,000 lbs.) with can goods and he made a really sharp U-Turn in our yard and the tires on one side came off the rims on one side! Any groove in the pavement that the tire edges catch the tire wants to track out of your lane. And in the snow and ice they are very difficult to handle (squirrelly). They look really nice, but don't handle well!
