Bolt Pattern

4/110 on the Pioneer. Pretty sure that 420 has the same.

Looked it up for you quick. The 07' Rancher does indeed run the 4/110 pattern.

Bolt pattern is the same but the rear offset is wrong. They would be really wide (stick out) on the pioneer.

is the rancher a AT (IRS)or have a SRA ?

07 would be SRA, the AT didn't come out until 09.

Thanks everyone! I think I may still have my old rear rims which will do until I buy new ones for all 4 corners

If I might just pick a brain or two just to confirm, but will I need offset rims to install my 26x12x12 Mudwolfs on the rear or will there be ample clearance? Our dealer does not have anything for me to physically look at until April. I would mush rather use my free old stock ones of course, but they did not fit on my atv, which is the old straight axle of course.

if you want to use the stock wheels from the pioneer on the SRA rancher just flip the rear rims around so the valve stem is on the inside .........(it is a pain to air up but not all that bad )

The factory rear offset is 5 3. I have 11" wide 28" on my rears on a 5 3 offset rim. I would say you would have clearance for a 12" wide as I believe a couple people here already run 12".

I love all the info (and people on this site!

Are you wanting to mount the tires on the stock Pioneer wheels and mount the tires off of the Pioneer on your Rancher wheels (which I'm guessing you found a 12in wheel for the rear)?

For some reason in my head I was thinking that I would just simply swap them as they were/are, but in retrospect I will mount the mudwolfs onto the pioneer wheels and vice-versa for the quad. I did have 12 wides mounted onto the stock rears of the atv, but they were stubborn to get seated, but then of course did not fit. What are yoyu thinkin' as I could be flawed in my thinking.

Oops. I did not even look for my rear rims last night as I got back from the drilling rigs well after dark.

If the question is. Can I mount a 26x12-12 on the rear stock Pioneer rim? My answer is yes.

Yes is the answer! Now what is the question? Thanks Moose!

You 420 in stock form had 11in rear wheels and of course the wrong offset for the Pioneer. One of the reasons I'm asking so many questions to make sure you updated to 12in wheels on that. If you did and are swapping tires between the machines (tires only) you will be good to go.

You bet sir and thank you.

Howdy fellas, I been trolling around the site for a few days now, and haven't found the answer i was lookn for, I'm sure i looked right over it. I got my name on a list and should be burning up the trails by the 12th of this month on a green pioneer 4. My question was on the offset, I been lookin at the MSA M20's, they offer a 0 offset and a -52, I'm guessing the 0 is what i want, but how will that set on the rears, plan on running 27x12 on rear and 27x10 on fronts. I don't want something sticking out past the the fenders bad or anything that will rub on the inside. Thanks, Rob

Not sure what those offsets will do, but I know the factory offsets are 5-3 rear and 5-2 front. Look up Moose's machine, search 28" big horns, and have a look. He is running 5-3 offset front and back. Maybe it will help you with a visual. Seems like zero, which would have to be the rears, would just add a bunch of unneeded width to an already wide machine, but really depends what you will be using it for.
