I don't think you will see super singles take over any time soon. They are best for guys like fuel haulers that run short and almost always half empty too boot. When a super single goes out, it many times will take the rim along with it. Way too expensive a proposition for most at this point, plus the fact you can't get them everywhere like other tires. Our Michelin dealer and rep told us not to even think about them a couple of years ago. They were not for our kind of operation. One more disadvantage...they suck in snow!
