    i have a trailer with wide based tires. wide based and duals both have there own advantages and disadvantages. i don't know that i would swap one for the other. in a trailer position i would not spend the money to switch s/s to duals at the same time i wouldn't spend the money to swap duals for singles. i think there own advantages and disadvantages kinda wash each other out. although i would highly recommended a tire inflation system on s/s or really duals for that mater.

    I paid only $4250 to switch from worn out duals to xone line energy d's and got xza3+ for steers. $4250 out the door. So it was a no brainer for me.

    That's not bad. Did you get 10 casting and rim 8 credits?

    I thought of switching on my last truck but gave the idea up. When I ordered my present truck, I figured that was the time to do it right if I was going to wide based. That is why I spec'd intermediate length drive axles, I get a wider stance, and still can revert to duals if I need to and still be at the max 102" width. It allowed me to get the best of both worlds, a little wider stance and using 0" offset wheels to maximize bearing life and reduce any potential problems with tire wear. It has worked well.

    Given that the Michelin Energy tires are also offered in standard low pro 22.5 tires, converting to wide based on an existing tractor just doesn't seem worth it, except only for weight savings, and there are other ways to get that weight saving that would be cheaper. It really only makes solid economic sense to go wide based from the factory.

    that is interesting to heard,

    here in europe we can get only normal axles ,no different sizes

    before swiss had narrow 2.3m width law so than all manufacturers had narrow version of cabs and axles , now only rare trucks for swiss have 2.3m width so this is pretty special

    here super single tires for drive axle come in 495/45r22.5 size on 17.00 rims with offset -50 and -67 , but it is very rare to see truck with them

    here almost all trailers have 120mm offset and it is not problem on bearings , all mercedes axles, and saf on disc brakes are 120mm , bpw offers both 0 and 120mm , in recent time 120mm are more popular at bpw , drum brakes are all 0mm but this is rare now even in construction

    Well said ! Just blindly pulling off the right set of duels and slapping on super singles may well not net any fuel savings , or worse. The RR number is the key. There are duel tires that come very close to the best SS tire. There are a place for both !

    IMO, The only big concern about SS is if u 'v flat tire and you did't pay attention, they can catch fire in no time

    Hadn't heard that one. Well, I guess I had heard it about flat tires catching fire, but it was the old tube style, 10.00-20s and the like.

    I 've EU 3axles trailers with 385/65r22"5

    it is common problem when they get flate, cuz the entire weight 'll be over the rim.


    , if other drivers signal to you, jump withfire distinguisher as soon as u can.

    and yes they sway a bit more when hauling containers
