22.5 or 24.5s on a flatbed spread axle?

granted my truck rides very low, the flatbed i pulled thru LS had 22.5LP tires also and I was able to load a 9' tall piece and still be legal at 13'6" overall height. It came in a handy a couple times

 

Michelin makes their LP is a 275/80/22.5

All other makes are a 295/75/22.5

They come out to the exact same size.... I only run Bridgestone's

 

17.5 Lets you pile it higher and the tail may be level with your truck

 

I have never seen a 17.5 on a flatbed trailer...

 

Not on a flat (obviously) but I see them on steps....the deep drops, or low deck steps or whatever you want to call them. They usually have a 29" drop IIRC. We had one years ago but we don't run them because we couldn't keep brakes on them. So the solution is to add a tried axle and then the weight goes up. So we bought a low deck with LP255/75R22.5 + wheel wells and we were happy enough to by a second one.

And to answer the original Q....all our SD and DD are 255-75-R22.5

 

yeah! what he said!!

 

I know that, Bayou was asking about tires for his flatbed and kwloo threw out the 17.5 size.... I was baffled. I've seen them on SD before many times.
