Let's say he chose a 20" tire for the rear instead of the stock 22" assuming the front stayed the stock 23". That rear tire would overspin the front quicker than the 22" making AWD either engage all the time or at least even quicker than it does stock. If he were to put a larger rear, let's say 24" with the stock 23" front it would now take longer for the AWD to engage. So if he went 25" rear and 25" front the AWD will engage later than the stock set up. The AWD engagement is based on a ratio of overspin (overdrive front to rear). Even if you went with 24" rear and 25" front the ratio may not be exact compared to stock.

I agree.
Thanks.

Okay guy's here is the cold hard facts. We are going to compair a 2004 scrambler 500 4x4 with a 2002 explorer 400 4x4. The reason for the 2002 explorer is that it was the last year they made the explorer. If you look up both machines on the polaris website and look at the break downs you will see that the front diff has the same gear ratio between the two machines. Second the trani's have the exact same gears inside except that the explorer has a low gear, thats why an explorer trani will bolt directly into a scrambler. Third they are running a 13, 36 gear combo for the rear. Last if you look at the factory tires on the explorer they are 25-11-10 on rear and 25-8-12 on the front. The awd drive works off of a percentage of slip of the front to rear. Some machines have a smaller percentage than others, but it does work and won,t hurt anything if you run the same size tires on the scrambler. I have run my machine in everything from super deep sticky mud to dry hard dirt to sand and snow. Hope this helps and good luck with your decision.

Tire slippage keeps different than stock tire ratios from being a problem. The fact that we ride with a solid straight axle out back and can actually turn the thing shows that they are slightly slipping at just about any time. You know the difference in turning on dirt, mud and sand versus pavement. So if the front/rear ratio is a little different than stock, it slips enough to keep from binding.

so what happens if u drive in awd on pavement then? if the tires cant slip and its gonna automatically be in 4x4 becuase f the tire size difference will it be basically the same affect as putting lower gearing in the front of a truck than in the back axle. causing the front to swap with the back?

Sorry Mike, I have the ability to give you pictures, but I just stripped my quad down for a monster rebuild. I will post pictures when it is done. It's getting solid motor mounts, a 5" extended swing arm, 26 or 27" tires, a explorer trani. and some engine mods. good luck with your and safe quading for everyone.
