Super single Question

robertglines1 · January 07, 2012, 07:12:42 PM

I can think of allot of negative- but got a chance to pick up four 1 yr old on alcoa rims for 2 grand. My buses call for 315 80r 22.5 I have pressure pro system. Just in the thinking stage now. The tires are off a wrecked semi and I need to recheck size. I know it is a 2010 volvo. I have seen entertainer coaches recently running them. Bob

This subject keeps going around & around. From my view point, the super singles are great tire setup, however for the RV user, just remember when you have a flat, you are dead on the road just like a trucker, only the trucker has a setup with either their own shop of a national account with a tire shop, you do most likely do not. Getting a replacement is only part of the issue, the other is the price for the RV'r is not going to be a bargin.
Me, I am old fashioned, and I only put about 20 K miles a year on a coach and can not justify the expense to look cool.
FWIW

With the super-singles get more and more available, my take is this, if you have a flat, and no spare, you are going to pay that 'premium' no mater which tire you have regular or super-single.
I personally think I would carry a spare, sure it takes room, however you purchase it on your schedule, not the broke down, flat tire schedule that gets you ripped off!

Bob, you will need to check how the rims are mounted. Many of our buses are stud piloted ("Budd") but late model trucks are hub piloted.

Truckers don't run these tires to look cool. They save a bit on fuel and that is really the only reason they run them.

If one has dual tires you can run for a bit on one tire on one side, or remove a wheel from the tag and put it on the drive axle to limp to a tire shop. You can't do that with a super single.

With truckers it is fuel mileage and weight savings (300lbs over 8 aluminum mounted duals). Fuel savings-if the most fuel efficient duals are rated at 100, then the super singles are rated at 85 (count of road resistance).

With both Freightliner and Western Star, the super singles are no longer an over the board switch. At first you could swap out the duals for the super singles running a 2" outset wheel. But it was found that the outer bearing on the axle was carrying all the load making for premature bearing failures. Now we can only order the super singles if we also order the 6" wider drive axles that allow using an 0" offset wheel. You can still change the zero offset super single back to duals, but with the duals out at 102" wide-which will look a bit funny since tractors are still being made at 96" even though most are pulling 102" wide trailers.

For our use, I would stay with duals-unless of course you absolutely have to have the cool factor of running the super singles. Good Luck, TomC

Bob, the entertainers that run the super single also run the 365/70R 22.5 on the tag and steering all the 18,000# front end Prevost use the wider 365's on the front now

good luck

Would be to much to change all the way around. Just looked like a deal. Tires have went out of site$$ Even my 2 or 3 yr old supply has gotten tight. Worth the asking. Bob

Do you have Budd wheels as Jim previously mentioned?

I know the 01 H3-45 at my work still runs Budds.

robertglines1 · January 09, 2012, 05:31:36 AM

Yes I do have bud wheels. Was intrested because I have a 89 and 98 and deal was for four tires and rims. Was going to put two on each. was 2grand for 4 which would be like buying 8 of the 315 80 r 22.5 and included rims Just looked like saving 4 to 5 grand up front. Yes and be differant also. Bob

luvrbus · January 09, 2012, 05:46:32 AM

Both the pilot and hub mount are 10 hole mount when Budd came out with hub mounted back in the day they were called "unimounts" so says my old Peterbuilt manual lol a little history a friend here is still buying new trailer dumps with the Dayton type spoke wheels and I thought those things were gone years ago

good luck

One of the cautions in buying tires from a wreck is that they may have been flat-spotted in the course of the accident.

Pardon my ignorance, but do they make super singles that are compatible with the old budd / stud pilot hubs?

Or are you planning to switch out the hub to a hub centric?

That was my dilemma when I went to 24.5s last summer, and I chose the cheap route - getting 4 budd rims.

robertglines1 · January 09, 2012, 05:17:58 PM

These are bud type/stud centered. Bob

TomC · January 10, 2012, 09:00:38 AM

The new super singles are only hub piloted. I don't believe they make the low profile super singles (not the construction tires) in stud centered/Budd type. Good Luck, TomC
