I don't know exactly but if you can get the width of the wheel and the MM number off the inside post, you can use this converter to get the back space. The balance is the second number of the conventional offset.

factory front wheels are 7" wide with a 4+3 offset.  Factory rears are 8" wide with a 5+2 offset.
I can imagine a world completely at peace.  A world where there are no weapons, no war, and no violence at all.  And I can imagine us taking over that world because they would never expect it.

hey chuddly thanks, I was thinking about replacing mine with another style but was wanting
a little more offset but didn't know what to get.
what do you think ?

Here's an odd thing. When I was testing the Reapers off my Brute Force on the Z, I just swapped the wheels and tries straight across. I have 14x8s on the Brute, all the same with 5+3 offsets. When I put them on the Z, the width across outside to outside of the tires increased 3" over the stocks. Both are 9"s wide so I'm not sure..at least the 53s.. have a 4+3 on the front. You would think if they did, the width wouldn't change as its the +3 that sticks outward. I liked the increase in stability enough that I bought 1.5" spacers for the stock Z wheels.

Maybe tomorrow I'll pull some wheels and get some numbers.

I dont know what the trails (53" wide machines) have on them.  I should have clarified that I was talking about the EX.  I just measured the stock wheels on my dads EX last weekend so I KNOW those measurements are dead on and my EX is exactly the same.  In stock form the EX is ~59" wide (just slightly over it depending on your tire).  I put some 8" wide wheels on my dads '16 EX that have a 0 offset (or its called a 4+4 depending on who sells them).  This pushed the width of the machine to ~63" (also depending on your tire).  Of course this all makes sense if you do the math because on each side you are pushing the wheels out 2" so you gain 4" of total width.

Well I took some measurements on my 53 and here’s what I got.

The fronts are 7” wheels with a +23mm back set and the rears are an 8” wheel with a +46.5mm back set. If I go strictly by the stamped mm back set, I get a slightly different reading then I do if I physically measure but it does give me a result closer to what I found when I swapped tires and wheels with my Brute. So let’s do that first, then we will do the other way.
So per the converter, a 7” wheel with a backset of +23mm yields a total back space of 4.91”. Remove that from the 7” total and you get 2.09” to the outside. (4.91+2.09=7)
Here’s the pics and the calcs. The pic of the width was out of focus so I deleted it:





Ok, for the rear, It’s an 8” wheel with a +46.5mm backset. This yielded a surprising result but maybe it’s because of the tire width, hub or a-arm position. This results in a 6.33” backset  so the offset would be 1.67. (6.33+1.67=8) And its doesn’t look like that at all if you look at the wheel…but even the physical measurements show something like that. Here’s the pics and calcs:







OK, now let’s do it by physical measurements. One has to keep in mind..as I understand it..is that a wheel’s width on an ATV is measured from and to the inside of the beads, not the outside like an automobile's, like this:

http://www.pureoffroad.com/assets/images/Shared/POR/main_images/52_offset.jpg

So when doing this you have to subtract what the thickness of the material is…or what you think it may be. In this case I will guess that the wheels are about ¼” thick. And you always measure from the wheel’s mating surface so for the front I got 4.5” so..4.25” on the back side and 3”..so 2.75” on the front side. This equals 7”. Here’s the pics:







Clearly this may not be the best way to do this. But let’s continue onto the rear.
The rear backset measured 6” so..5.75” and the outset or front side measured 2.5”..so 2.25”. This totaled the 8”.  Here’s the pics:







So…there you go. In either case a full +3 will give you more and a +4 would do even better if width isn’t a factor. One thing to always remember though is that on any IRS or machine with a single wheel bearing, you always want wheels that have the first number equal to or larger then the second to maintain proper bearing loading. So..anything like 4+4, 4+3, 5+3, 4+2, 5+2 are all OK to use here.

Man NMK, you went to a lot of trouble, but I sure do thank you for it.
It really cleared a lot of questions up for me on rim choice, I was looking at some rims that were 5/3
so I guess these are ok......

No problem. Yeah I think 5+3s will be fine. That's what I have on the Brute and they fit fine. One thing however...when you put different width tires on the same width wheel, you will find there will be a small size or diameter difference. Found this out on the Brute where I originally had 11" wide tires all the way around on the 8" wheels but changed to 9s on front with those same 8" wheels. That make the fronts about 1/2" shorter then the backs. If I had put them on 6 or a 7" wheel it would have been the same...so they say. It also makes the wheel bead edge stick out almost flush and in the firing-line for rocks...and other things. Just to give a visual, this is the bead of my 11" tire on the 8" wheel. Perfect:




And this is a 9" tire on that same 8" wheel.



It's best to have your wheel 2-3" narrower then the tire if you can. More makes the bead set wrong as well as the contact patch and less does the same with the bead and exposes the wheel to impacts more.
