Tractor with 24.5" low pro

Advise for what? Here's my suggestion, hook up and go. I don't understand what your trying to seek. Long as it has the same size tire on each axle.

 

Depends on your rear end ratios.
Those tire sizes would make just over a three percent increase in engine rpm for the same speed.

 

They say that lopro 24.5 is the same as 11r22.5. Tall rubber sets the truck about 1 1/2" higher. So don't go under bridges that are marked 13' 6" exactly with high rubber.

 

Mileage depends on your gearing(part of the equation), but if your worried about height, it's safer to get the measuring tape out.

 

Dave, if they even have one and know how to use it...

 

Is there a "standard" 5th wheel height? I realize the higher your 5th the higher the top of the trailer. I've been meaning to measure mine....but it's quicker to ask here while eating breakfast

 

But if it's 13' 7" you can go fast... just close your eyes.

Hey, it worked for me

There are different hgt of 5th wheels and mounts. Tanker trks have high pedal mounts..
