Got Super Singles?

I've run SS's for two winters now on I-5 and I-90, Sumner Wa to Northren California and Sumner Wa to Western Montana. I haven't had any issues. (or let me put it this way, the chains don't go on until the chain law goes on).

SS's chain pretty quickly, as the access to the back side of the tire is good. However, each chain is heavy, about twice the weight of a standard single chain for a dual. The cross links need to be flat and square across the tire. If the cross link has a twist in it, it will cut into the tread.

SS chains are expensive, hard to find, and easily break. Push above 30 mph and the cross links start to break. I bought a large bolt cutter and have been using 5/16 quick links to rebuild the iron.

I have been thinking of getting a set of cables for this coming year.

They do. That's why if you order a new trailer you have an option of getting the same size for both the inner and outer bearings. And if you order the trailer with the SS I believe they automatically do it.

Just a question, are "On-Spot" chains legal for SS. By legal I mean do they pass when the law is in effect since the chains only cover less than half the tread width?

 

Dealer will suggest parallel bearing ( P spindle ) if you get standard bearing
( N spindle ) and run singles you lose your spindle warranty. just like putting dumps on a spread axle

 

I did some diggin', and spec'ed out supers for both truck and trailer. Here's what I found:

Michelin 455/50R22.5's (not the lighter 445/50's, I run heavy ALL the time and want the extra load carrying capacity). Lug type for the drives and ribs for the trailer, will save about 650 lbs over the 295/75R22.5 dual set up.

Now, here's the catch. If you you want to avoid the roadside service horror stories, and carry a spare, you're gonna add 250 lbs back onto the rig. So, you end up with a 400 lb net gain. Doesn't seem worth it to me, besides, who wants to wrestle around a 250 lb spare.

Now keep in mind, this is with the heavier 455/50's. If you run the 445/50's you'll save about another 150 lbs.

For what it's worth.

 

Our company ran ss on the trailers Im pulling, and I was glad to get rid of them. ou have to run them at least at 110, which may contribute to the bounce. Yjry handle poorly on doubles, and the tread seemed to have shorter life at least with our type of service. Off road alot and heavy, always loaded to max-gross. Flats leave you sitting waiting for a tire man, and usally a wheel also.

Maybe as a on highway only application that was not always heavy they might be better.

 

Good post Graymatters... thank you

 

don't agree w/ the weight savings you posted i saved 890 lbs when i switched to 455/50 wide based tires from 1100/22.5 duals.have had no problems w/them. didn't like them on my spreed on the trailer. didn't get enough life out of them. carry a spare tire that is down to 6 or 8 32 nand it will only add nabout 80 to 100 lbs w/o wheel. cable chains are easy to put on and have a good life if you keep speed down to 25 to 30 like they are suppose to run at.

 

Thanks. The numbers I posted were off the internet, not "real world" numbers. There's no substitute for "real data". Thanks, again.
