Gotta ask….Whats a Super Single? Hope this does not show my newbie side

one large tie replaces duals on drive axle. You are beginning to see them on semi trucks. Bob

So, what is the advantage? I don’t see many trucks using them out West , could that be they are staying ready to chain-up?
-
Now, with Suoer Singles do we call 18 wheelers, 10 wheelers ?
There will be much confusion at truck stops. Go ask a trucker to move his big over the road “10 wheeler”.

cost initial less— better fuel ecconomy in tenth’s per gallon. Usually large fleets. Dis:: one tire flat you can’t limp in. Reason I ask is have a chance to get a deal on two low milage one year old with rims off wrecked semi that will fit 98 with correct size tires for coach for $1000 for pair rims and all. Actually it is four for 2 grand and was thinking about all four and putting on both coaches. I have a 89 Xl also. The dual vs single flat thing is the only draw back I can see. In 22 yrs I’ve only had one flat on a drive tire and that was before sensors. So??

When I was at Prevo in Nj last fall, the mechanics there told me that a few charter companies were moving to them. I don’t think most RV owners will have enough miles to see the fuel savings.

Good to know. I might just pick up one and put on coach to see how it looks. Four tires and wheels for 2 grand = same as 8 tires and wheels is a big savings in this case. Tires apear to have around 15,000 miles on them according to papers and are 2010 mfg. I would probably never wear them out before they dry rotted. I know guy well and he will let me try and check clearances.

Super singles require a shorter drive axle. I was at the factory and took pictures, asked and that was the result. Better check with Prevost before you make a tire purchase.

I’ll play curmudgeon on this issue because I have had on the road tire issues.
In both cases I never lost any time in my travels, but in both cases I could not get direct tire replacements. If a schedule is not critical I see no issues with a coach with odd size tires. When we started out with our first coach we had 120 tires. At the time all the truckers were running 110 and bus companies that had 120 tires usually did not own them but leased them. My point being when I had my first road hazard failure my option was to wait a day or two for the tire company to get a 120 or I could have an 110, put it on the tag and keep on schedule. That is what we did.
If I fast forward 10 or 12 years the same thing happened with the current coach and again a 315 tire was not available so the odd size replacement was thrown on the tag and the 315 from the tag was thrown on the steer.
As soon as a coach is fit with 365s on the steer, a road hazard failure effectively shuts the coach down until the correct size tire is available. Add in super singles and the problem of finding a replacement size ramps up dramatically. The question is not if you experience a road hazard failure, but when. If the failure is catastrophic, and not merely a tire losing air are you prepared to drive the coach on the rim to the next exit or some safe point to remain while awaiting a replacement? Big fat tires look neat. Big fat tires may make for a smoother ride, increase the margin of safety due to axle weight, or just make the coach look cool. But consider that there is a downside.
I will admit I have started to get away from the 6.70 – 15 bias ply tires on my cars.
