SS on spread axle flat bed....

I did you form and 2 17.52'' tires per axle on a 10' 1'' spread the front axle is 20k the 2nd is 17,250k and with 4 10'' wide dauls is 20k per axle

 

Pop a conventional tire and it'll tear ish up too, then continue to tear stuff up if the driver "limps" it in. I've replaced a lot of airbags because the driver continued to the TS with a blown inside tire

 

How did you come up with 20k lbs on the lead axle and 17,250 on the rear???? Either way you still can't go 40,000lbs on a spread!!!

 

2 17.52" wide tires per axle at a 10'1" spread and that's what the chart have me

 

as I know SS tire is wider the trailer single tire used in Europe. I run 385/65R22.5 tires on trailer, but I have tridem, not spread. SS tires are wider, as I remember 435/45R22.5. so less pressure on pavement. So as I know u can easily change twins with SS and I'm sure u have some weigt and MPG advantage, but pay attention how expencive are SS tires and SS rims. Too many tires are usually damaged with sharp stones, road bumps and some lost on yards stuff. To purchase conventional tire is much cheapper! so I'd think twice

 

truck makers say, u have about 100-110 kg per axle pay load advantage with SS. So with four axels on SS - 440 kg up to 1000 LBS... sounds cool. Well, 5-9% of fuel economy.. sounds unbelivable, I sugest about 3%
