Running different tire sizes F/R

I'm looking at running 38" tires on the front since it will only have a D44, and something larger on the rear, anywhere from 40-44" since I plan on using a Full-floatin D-60HD

Restoring a '74 DJ-5C [img]/wwwthreads_images/icons/cool.gif[/img] It was running good, so I messed with the carb to make it run better. Now it wont run at all! [img]/wwwthreads_images/icons/mad.gif[/img]

Re: Running different tire sizes F/R

Some mud runners will do this, usually swampers fornt boggers rear. I saw a truck in a mag. a while back that was susposed to bo a hot road, he did this, he ran different gears, never seen it myself, might put more stress on certin parts since weight distrbution is angled forward

'95 YJ, I-6, Auto, Open Diffs, Soney stero, 215/75R15 GoodYear At's, Completly Stock, Getting tow hooks, Have big plans, lock right, 6" toatal lift 36 swampers, D44's

Re: Running different tire sizes F/R

I saw that picture too- it is what gave me the idea. I wont be lifting the rear any more than the front, just modifying the rear wheel-wells to handle these monster meats (If necessary I could lift the front a little more to compensate). The only actual lift from the tire would be 3" if I went with a 44" rear tire and 38" front tire. I also plan on having the rear axle cut down and playing with wheel back-spacing to keep the front and rear tracks the same, even though the rear tires will be wider. Has anyone found a SS TSL/SX in the 44" range? I've only found their Boggers and TLS that tall, and I dont want a Bogger since I'll only be running with a 6-cylinder engine

My question is, with 4.88 gears and 38" tires on front, what gears will be needed to run 44" tires without binding? I found that at 10MPH, the engine will turn at 300rpms for the front set-up. I put 44.2" tires into the equation and came up with 5.64 as the rear ratio, but does anyone make that?
