tire sizes and gearing change

I would like to run an executioner style tire on my 300 4x4 xplorer but the tires are staggered size. 22's in front and 24's in rear. Is there a gearing change I can do to run all the same size? I would like a 25-26 inch tire on the bike. I realize it will take more power to turn bigger heavier tires along with the gear ratio change happening with a larger diamater tire. I think tires of the same size just look better. I would like to run 10 inch wide tires front and rear as well. Any help would be appreciated. If this has been covered many times before I apologize. I have used the search but found nothing.

wondering same.
When its time to replace tires on my 2002 ranch-use Sportsman 500, I want to get a little more height, and switch to 4 of the same exact tires. Something with more flat surface area like the Terracross I've seen... for use in the woods, sugar sand, and occasionally in the marshy areas of the property. Like can I safely put some stock rear rims up front if I wanted to go super cheap?

I had a 99 Sportsman 335 with 23's on the front and 24's on the back. I upgraded to 25's on the front and 26's on the back. The dealership I bought the atv from stated that the offset in tires had to be kpet for gearing reasons. I ran that tire combination with no problems. It did rob a little on the top end but i was able to go through Mud Pits that 500's could not go through. My EX girlfriend had thd explorer 300 and I thought it had the same 23's on the front with 24's on the back. If you keep the offset you should have no problem. You may need to clutch your atv to help with the bigger tires. I run the 26 Executioners on my 700 and love them.

I've not seen any way to change the gearing of front-vs-rear. As you are aware, it would be bad news to change the tires without a gearing change. You must keep the same ratio of front circumference to rear circumference to not screw things up.

I did change tires on my '06 sportsman from 25" to 26". I didn't like it. It increased the effective gear ratio and I got an annoying loss of climbing power. I never tried to solve the problem with clutch changes. Sold it before I got around to that.

Based off your 22 inch front, 24 inch rear tire sizes, mathematically to run a true 25 inch rear tire the fronts would need to be 22.92 inch tall tire, a true 26 inch rear tire would need a 23.83 inch tall tire. Be aware that not only will the added height cause a loss of power, but so will the much heavier and wider tire you are looking at.

Thanks for the input. I had run into an old post that discussed changing sprockets to correct gearing to run the same size tires.But the fella had sold the bike and was guessing at the sprockets. Why is my bike 22 and 24 inch and other bikes are 23 and 24 inch? Is the gearing the same as my bike? I have looked but have not found any info on that either. A 1 inch stagger in tire size would be better than 2 in my opinion.

I just found a post that says use the 400 4x4 chain and sprocket set with 25 inch tires all around. It appears the only change is the rear sprocket going from 40 to 38 tooth. Is there anybody here good at math that can see if this would work? I looked at a 400 scrambler and it uses 35 inch tires all around. This would be great!

Oops, looks like it changes more than just the rear sprocket. 1996 400 xplorer is what I looked it up for.
