super singles
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

The super singles have largely replaced duals on tractors and trailers in western Europe, while duals are still common in central and eastern Europe. The newer tires are preferred by EU highway safety standards, but harmonization of national vehicle codes takes some time when you keep bringing new countries into the club, and a lot of traffic comes from outside the EU.
My last few visits, fall 2010 Iberia, France, Italy, spring 2011 France, spring 2013 central Europe, I've been keeping track of what has been on motorcoaches vs trucks, and guess what? All running duals on the. drive axles. Maybe because this means six or eight identical tires, rather tha two kinds on two axles, or three kinds on three axles? It is not because wheels and tires are position interchangable, because they are not.
FWiW, in most of the countries, motorcoaches (still running the supposedly less safe duals) have speed limits 10kph to 30 kph higher than the heavy goods trucks running the newer, and believed to be superior, super single technology.
In this country, we'll be running dually on all our heavy axles unless situational economics makes super singles less costly in operation, or until this dually solution, dating from the early 20th century, is outlawed, as it has been in a few places, but not many.
