Last winter I seen a diesel pusher with super singles in the rear. A lot of over the road trucks are running them but there are very few on MH's. Just wondering why.:h
Super singles are much more expensive than duals, but have much greater wear, which is why the truckers use them. Motorhomes do not put anywhere near the miles on, like an over the road truck, so the tire would die from age, long before any cost savings would be realized. Wrong tire for typical application.
