You can if you don't engage 4WD.

How many teeth would you like off your ring gear?

How many pieces do you want your transfercase in?

Don't think about doing it. Not a good idea for a 4x4.

The actual diameter and the stated diameter may not be the same. Measure them and see where your at. My buddy's 35" boggers where actually less than 34" brand new.

this is the best advice. measure yourself and see. best way to do it is to chalk a mark on the tire (with the tire on the truck and weight of the truck on the tire) and rotate the tire one revolution. measure the distance the tire travels on the ground. do this for both sets. air pressure can really change the circumference of the tire, you might get away with running the fronts at 30 psi and the rears lower, say 10-15? but like i said, measure yourself and know for sure!

If you are extra crazy you could regear the axle for the circumference difference.
But seriously, I recall that ford used to have slightly different gear ratios front and rear in the 70's on some trucks. So if you are still extra crazy and only play in mud or sand you might get away with it if you don't have any lockers.

But I would not do it.
Never. Not even with some one else's truck.
The difference between 33 and 32 inch tires is about 3 inchs (100 vs 103 +/- 1/2 inch)
But that is only if the tires are honestly the size they should be.
(good luck with that)

I was at a tractor show, and some guy did a 4x4 conversion to a old ford tractor but kept the small front tires. so it is possible, but then again that was tractor that probably doesnt go above 20 mph

im sure that tractor had deeper gears in the rear to compensate for the tire size difference (or taller gears in the front, however you want to look at it)

Unless it was a trailer queen that is the case. A lot of the early front wheel assists were hydraulically driven and the driver had a lever he could adjust the front wheels to the speed that worked best wtih whatever speed the rear was going. There was no shaft going to the front, just hoses so speed difference wasn't critical. That would be an easier way out for a conversion as well (especially using a rear axle out of a combine)

Most are geared a little faster in the front otherwise they love to buck (the early shaft drive front wheel assists were noted for that)

What is generally called a 4WD tractor has the same size tires front and rear, usually dualed and steer by a pivot in the middle. Otherwise they are a FWA.

Hope you aren't going to use them on the street.
