Couldn't do tha the same thing by running 12R24.5's same hight yet just skinny enough i could still have the stability of dual rear wheel's ?

Joined: May 2005 Posts: 8,878 | Careful, There are a few different bolt circle diameters on the big 10 lug Budd wheels. For example, busses generally use a larger bolt circle.

What is the actual bolt pattern of the truck you are looking at?

The 22" tube-type tire and the 24.5" tubeless will have the same overall height, due to a shorter aspect ratio (height/width percentage) on the tubeless 24.5" tire. There are some very high profile tubeless tires for military use, but they're scarce and expensive.

Just keep in mind the newer style Budd wheel would be what's called a hub piloted wheel. | | | | | Joined: May 2007 Posts: 292 Wrench Fetcher | | Wrench Fetcher Joined: May 2007 Posts: 292 | ACCTUALLY ! i was do at the Truck stop and they offer both hub and stud pioted rim's in 22.5 and 24.5. . .
so as long as they meaure the same stud they can be swapped I did see an army rig with 11R22.5 T-831 traction tread's so a 24.5 will bolt right up. . .
the old 11.00-20 is 42" actual inches tall as the 12R24.5 is 46" actual inches tall well in the G-177 Radail Mud Grip. . .they'll only be about 2" shorter then the 14.00R20 and 4" shorter than the 16.00R20. . .
but i'll have an Over drive or 2 to make up the difference. . .
I'll just build another " mikeyplex " 15 spd. . .
MIKEYPLEX 15spd:
mack 5spd 5th= .76:1 3 spd auxy 3rd= .85:1 giving you .61:1 whitch is what i did for my B61T it went from running 58mph@2250rpm to 72mph@2,000rpm. . . with out a tire size changed. . .doing the same for the 10 Ton but i'm swaping the 5spd for a 7spd a little better split for the KT cummins . . .
