Got Super Singles?

I have no idea about that law. I would never trust the mileage from the ECM.

The ones I saw weren't for carrying an axle without a wheel (although they would work for that) They were for taking the load off a flat tire.

 

i have had them on my t/t scence 12/02 saved 900 lbs in weight. not sure about mpg it was new at the time. had problems the first year but michline stood behinde them.the last set that i bought 18 mo ago cost me $2100.00 . you must watch the tire pressure run 110-120 psi. i have 830,000 mile on truck got 325,000 miles out of first 2 sets think i should do 400,000 this time. overall a great tire. as for road side think about keeping a spare tire w/u. you can get a good tire only for $150.00 to 250.00 it will save u a lot if u need one. good luck harry

 

I have run a trailer with super singles and i dont like them, but the trailer was used hard, so not really a good test.The setup i used was nothing that could be judged for mileage. The trailer was bought used so ...
As for mileage, i would assume there is a weight savings and i have also heard that singles get better mileage because only half as many sidewalls flexing, using fuel. I dont know, just what i have heard?

 

How are the lug type super singles for driving in snow?

Anyone out there have experience with them?

 

Well one truck we have them on has a dead axle so it won't even move on slick roads but the other truck isn't too bad. It's never been stuck and it hauls grain off several farms and plowing snow isn't high on most of their priority lists. They do pull real hard in soft ground compared to duals.

 

what would be a ball park cost on the conversion to them? I have a '94 Peterbilt that is a work in progress and I've given a lot of thought to them.

 

Don't take my word for it, but I read somewhere that super-singles place greater forces on bearings and that some bearings won't withstand the greater forces. (They also move those forces further out, away from the bearings)

Like I said, don't take my word for it. Do some research.

 

i think if u really check it out uu could be right as how the offset is

 

the concern is for trailer axle bearings not tractor drive axle. myself and many others i know are running singles with the "wrong " bearing with no
problems. pulled my bearings apart after 250k and everything looked new.

 

Good to know. Thanks.
