Bigger tires on a BX23S

So after a lot of research and gnashing of teeth I finally have 2 in taller tires mounted and operating on my BX23S. I searched high and low for examples of anyone that's done this and could not find anything so figured I would outline what I did. As any BX owner knows the tiny little toy tires on the front leave a lot to be desired especially on bumpy ground while hauling heavy loads in the bucket. I wanted to ensure the front and rear ratio stayed within the 5% specs which I believe I have done by going to a 28x12-12-in swamp witch six ply UTV tire for the rears on 2-in spacers and a 20x10x10 357mag 6ply UTV with 2in spacers up front as well. It was quite a chore finding the front tires with the specs I wanted but this was the end result. I'm including pics so that the naysayers can see that there is in fact plenty of clearance on both sides of the rear. I do not have or plan to use a belly mower so that additional with on the new tires is a non-issue for myself but I believe the spacers would ensure adequate clearance. So far I'm absolutely loving the increased comfort on rough terrain not to mention increased traction on muddy job sites. Hope this helps anyone thinking of doing the same. Also found a set of 8-in rims and tires combo that will work but only with a 2-in spacer up front they would not work mounted to the factory hub.

Looks good, I image the larger fronts were easier to mount than the stock size, even though they were 6 ply, compared to 4 ply.

I run stock size on my SCUT, but went to 8 ply on the front, but only run 10 psi in the rears for comfort (if you can call it that!)

Have you measured the difference in top speed? How has it effected the low end "grunt" to pull or push! Do your stabilizers pick your rear tires off the ground now?

I haven't actually measured difference in top speed but I've noticed in second gear it whines a little bit more about going up steeper hills full throttle, that being said first gear has become more usable especially for bush hogging on my farm which was too rough and hilly to do in second gear at the same time first gear was a hair too slow even with the pedal to the metal lol.
