tire size

Ground clearance. 22.5 tires are too small out in the bush.

 

The shorter tires have a lower effective gear ratio, so they will pull better with everything else the same.

 

I had 11R24.5 pulling 140,000 lbs. switched to 11R22.5 looking for better fuel economy trying to run in what I thought was my engines sweet spot.
Did find it pulled better, but fuel economy went down. So I switched back 18 months later when I wore out the drive tires.

Yes, ground clearance is one of the reasons for oil patch and I went off roads into farmers fields.

 

Isn’t the 24.5 16 ply rated for a little more weight than a 22.5 16 ply……

plus less revolutions per mile …….

 

11r 24.5s are a few pounds more then 1122.5s but 12r22.5s can carry more then 11r24.5

 

Price and availability is also a factor. 24.5” rubber is not nearly as common. If that’s what size it has factory I’d consider switching between lo pro and talls depending on what the goal is, but replacing 10 wheels and tires at the same time would be an outrageous bill and probably not worth it.

 

In the Northeast all the locals run them …..

 

Switching over to 22.5's right now the cost is about the same with new rims, as it was for the last full set of 24.5's they are getting more expensive because there is less companies making them
