Switching from 11r 24.5 to 445/55 22.5

If you order a new trailer with super singles they put in a heavier axle. Most of the weight savings is lost. If I remember correct the up charge is like 4k and they don't give you any extra when you trade it back in over duals. I figure payback on two years because that's how long I keep them.

 

U will gain 3or4 hundred RPM

 

It's more like about 150 RPM

 

Offset is very important when switching ! 0 offset is best to stop axle flex. 2 inch offset is bad for axle flex. Have heard flipping the 2 in offset yields good results, 1/2 offset if not wrong. Getting track 1 inch wider , total . Shop around for used rims , can save a bundle! 0 offset put the load center over the bearings.

 

I wouldn't do it. Singles aren't all that great. Just talked to a grain hauler today when I was waiting for my truck to heat up. He didn't mind his and only ran them on his tractor. Said he saved about 700lbs, but he was going back to duals noticed no fuel savings what so ever. I've always ran duals and always will. His biggest complaint was picking up nails and what not and being completely screwed. You're running a hopper, there's a lot of crap laying around the elevators you can pick up in tires. I wouldn't recommend it. Yea you get a 700lb weight savings. Hauling wheat depending on what you're getting per bushel you're looking at maybe $6.50/load. On DDG or a tonnage rate you're not getting much back either. Not to mention the problems in the winter if it snows. Or if you're loading off the farm, the traction loss in the mud. That was another complaint of his traction. Dry pavement he didn't notice much of a difference. In the mud on the farm, no traction he couldn't dig in like a dual. I've got stuck with duals before, but it would've been worse with singles.

And as stated with the trailer there is virtually no weight savings after the new axle, You're better off with duals. And if you're running a spread axle hopper you'll lose a lot of tire life as singles don't wear well on spreads. I don't think highly of singles. Never have I know there's some people that will disagree with me. But I'm also no sitting on the side of the road waiting for road service is a tire decides to let go. Don't have a $800 bill for a new tire and another $500 bill for a rim either. Nor do I have to worry about them finding me a tire either.

 

We switched our hoppers to ss. We came up with about a 400 pound weight savings.

Going on two years and have not had a single issue with them.

 

300 rpm. At 1600 with his set up the 24 run 77.8, at 78 mph with the 22.5 eng rpm came out 1900 rpm. I could be wrong done the math in my head assumed his 18 has .73 overdrive. I think he is just looking to gain ground clearance if he gonna pull a hopper.
