Read the Shock Therapy wheel offset thread. I went with 5+2. No regrets.

I have read it. Just looking for feedback from those that have been running 4+3 for a while since I already have those rims. Don't want to buy new rims if I don't have to.

What tire size /wheel are you running?

Im looking at a set of wheels, but need help figuring out what the offset is

so its a 7" wide wheel, backspace is 4.51, offset says 13mm . anyone know how to tell if that's a 5+2 or 4+3?

Have 4+3 on one rzr and 5+2 on another and you can drive them back to back and the 5+2 is definitely the best the one with the 4+3 wears the bearings out twice as fast

Backspace is measured from one edge of the wheel. So simple math,
7"- 4.51= 2.49 which would be 4.51+2.49 wheel
Offset is distance from center, being 3.5"(half of 7")to the wheel mount flange,+13mm(.5). So the centerline is shifted over .5" adding that amount to one half the wheel, and subtracting it from the other half.
3.5+.5=4
3.5-.5 =3
4+3 wheel
The backspace measurement may be skewed from a measurement on the outside of the wheel vs the bead area

Back space measurements are generally taken from the outer edge of the wheel and not inner edge that mounts to the surface of the hub. A true 5+2 wheel would have a BS of ~5.25".

A true 5+2 wheel has a +38mm of offset and a 4+3 has 13mm.

Your best bet is to call the rim manufacture. To put it bluntly they, the rim manufacture will list a rim as 4-3 or 5-2 but it is not. So call and ask. I called MSA before I purchased my M12 Diesels. I had a few rims I was looking at and they were all listed as 4-3. They told me that they list them Generically or close to but not exact. Out of the rims I selected they told me that the M12 would be the closest to my stock width. But it would make me less than 2 or 3 inches wider. (sorry can't remember exact number)

I have also read that STI has some rims that are exact as our stock offset. But I don't like any of the STI rims. Anyhow I would call before I ordered a set of rims unless you have seen them or know that particular rim and offset.

I think MSA measures there rims in MM and they convert it to inches. Goodluck.

A lot of the wheel manufacturers use the X+X measurements very loosely. Both Raceline and STI sell a +30mm offset wheel that they call a 6+1. +30mm is a 4.7+2.3. Methods 5+2 and 4+3 are actually what they say they are.

Im curious why you quoted me? None of my info was misinforming. I did not state backspace was measured from the hub mounting surface.
Actually Backspace, hence the name is measured from the back of the wheel.

Just expanding on what you said.

So I'm looking at a set of 32' Carnivores on STI HD5's (5+2) back spacing. How much wider will I be? Anyone have first hand experience with those wheels?

The HD5 is a +30mm offset wheel which makes it a 4.7+2.3. The stock front wheels are a 5+1 and the rears are 6.5+1.5. So, you will be 2.6" wider than stock in the front total and 1.6" wider in the rear.

That 2.6 inches would be split in half so 1.3 inches per side?

Any other wheels I should be looking at to keep the width to a minimum??

Yes, 1.3" per side in the front and 0.8" in the back. Methods makes both the 401 and the 403 in a legit 5+2 at 38mm of offset which would make you 2" wider in the front and 1" in the back. Pretty minimal from a width standpoint compared to the STIs.

Walker Evans makes a 15" 5+1 wheel if you are okay with 15s and the Walker price tag.

Thanks for the info. None of the Methods wheels are to my liking. And I don't feel like running 15" wheels. Prob stick to the original plan.

I have methods on my shoping kart, but i would like to know which rims size should i go 14x7 or 14x8 to run 30x10-14 tusk terrabite

So I got my new wheels installed today, I went with 15" Method 401's in a 4+3 offset. I wanted to update this thread with some exact measurements so that future board members in the same boat can search and get a definitive answer on the width subject.

Stock XP1K Wheels & Tires (Before)
Height - 75.25"
Front Width - 66.50"
Rear Width - 66.25"

Method 401 4+3 15" w/30" Mongrel's (After)
Height - 75.75"
Front Width - 70.00"
Rear Width - 68.75"

*All measurements take from tape measure on the floor.

How wide is the rim? 15x7 or 15x8?

Definitely stay with a 14x7. From there you can either go with a 5+2 or a 4+3 depending how wide you want to be. To the keep the steering geometry (scrub radius) in check the 1000 needs a 5+2 but on your 900 I have heard a 4+3 works well so I would go that route.

Not to bring a thread back from the dead but where did you hear that you can go 4+3 on a 900? I am looking to go that route and wondering what makes the 900 different from the 1000 in terms of changing the scrub ratio. I can't find any information on it.

I was basing that on what Shock Therapy said in their scrub radius article they did a while back. Spindle design is what determines what offset wheel is correct for the application.

From the article: "You may wonder why, the wheel company’s offer a 4/3 or even bigger offset wheel if there are so many issues with it. After all, they should know all about scrub radius right? Well, the reason we have heard from some in the industry is that the 4/3 offset was perfect for the RZR 900 front spindle. When the 1000 came out with a wider axle length in order to get more travel, the extra width went into the spindle design and into the wheel offset of 5/1. Since the wheel companies already had the molds and tooling for the 4/3 offset they continued to sell them while they developed a 5/1 or 5/2 offset. Good or bad, that was it."
