Wheel genius or wheel stupid?

So I've been thinking. The height of the 225/70/19.5 is 31.9 inches. You can't air down a 19.5 for traction because it will come off of the bead because of the angle of the bead seat on .5 tires and/or possibly damage the sidewall so that that goes BOOM! when you air it back up.



So I need a 20" instead due to the different bead seat design. I can't find an Alcoa style wheel to fit my 10x225 pattern in a 20". My end goal tire is a 275/65/20 that is 34.1" tall (I know, short family). This tire has a slightly heavier load carrying capacity than the 19.5 but it definitely won't last as long. It will get me onto a beach in Mexico and be snow rated for Alaska.



I'm thinking about buying 6 20x8 steel wheels and cutting the center out and taking the 19.5 center and putting it in. This would also allow me to change the offset by one inch which will maintain the current space between the duals.



I would mock it up and tack everything in place to verify true and out out of round (because nobody likes wobbly eggs for wheels) and then take them to my welder for liability reasons to have him finish them.



The plan would be to remove a front wheel hub and place it on the bench. Then get a piece of 20x20x1/4 plate and cut a hole in the center big enough to go around the outside of the studs. Put a stock wheel on and weld spacers to the plate to build a jig that will maintain the offset. I'll rotate the jig while checking for out of round. Once everything is set I'll tack it up. After tacking I'll take them to the tire shop to spin them.

Sounds like a lot of liability to me anyway,that and I wonder how it will affect gearing/speedo on your truck.
Speedometer is completely off. I'm putting 08 F450 axles with 4.30 gears under our 2000 3500hd that had 5.13 gears. We will be changing transmissions from a 4L80E 4 speed to an A1000 6 speed in the next phase of this build.

I had a 54 chev 1-ton that someone had done the same to the front wheels. Welded 15" rims to the original centers. Absolutely no problems in 10 years of driving the truck. I wasnt,, and still aren't, familiar with the stock running gear for that truck. The previous owner swapped out the rear and I think the front to a standard 8 bolt pattern.

1t truck in 54 should have the same 8 lug bolt pattern as a truck up till the 80s anyway.
After that quit paying attention.

Dakota digital makes a little box to adapt the speed sensor if you don't want to do it in ECU programming.
When we eventually do the Allison swap it needs a stand alone controller and we'll take care of the speedometer at that point. I'm not concerned with odd shift timing. I'm also not the biggest Dakota Digital fan. I've used a couple of their adapter products that just haven't worked well. I currently have a pass though VSS in my LS swapped CJ5 so I could retain my analog speedometer and have the VSS for the PCM. I've tried two of them and neither one reads.

"Have you ever been there?"

No need, our current "menstruation" is bringing all the more serious problems to a town near each of us - cool project tho ... Steve
