My $0.02
The single tires you see on a typical OTR truck of today are correctly called wide based singles. Super singles made the markets many years ago and were pretty much relegated to specific industries/tasks for the trucks. They were a much taller tire and had less tread width than a pair of dual tires. Wide based singles are a lower profile tire with a substantial increase in tread width comparable or greater than dual tires. Two reasons they are typically used, weight savings and fuel savings. My own experience tells me that the stability and ride are not as good as dual tires. Driving in inclement weather is also made more challenging with them. As many have said here in previous posts, those who buy them are not usually those who drive on them. There is truly a savings to be made in weight and also some savings in fuel on a typical 18 wheel OTR truck when used in all drive and trailer positions. The benefit on a MH would be minimal at best. Most people rarely ever get a flat tire but if you use the wide based singles, where you get the flat is where the service truck will find you to change/repair your wide based single tire. I don't drive enough miles in a year to recover anymore than minimal costs associated with the purchase/conversion to them or to make me put up with any of the other issues.
As I said, my $0.02
Stay safe all.
