Well, we have the final answer. You cannot put 12" 570 wheels on an SP. Tried to push the wheel on and the bolts wouldn't go through. You can see from behind that the steering arm will not clear inside the rim. So now we know for sure.

I have been running 14 inch rims for awhile now with no complaints. Why do you want the 12s ThorsHammer ?

Seems like the general consensus here, and I tend to agree, is that 14" wheels don't leave enough rubber around the outside. That creates more pinch-flats that a 12" wheel. That said, I've had not trouble with mine the last 6 months.

 

[ThorsHammer]

I don't want an SP so it's a moot point. The whole point of the thread was to be able to prove to people that are asking that they cannot fit. There have been several threads of people speculating one way of the other. But now we have proof to refer to for future questions.

Psssh I have been saying this for months.

Can someone explain what a pinch flat is and how sidewall height is involved.

Pinch Flat

Can someone explain what a pinch flat is and how sidewall height is involved.

A pinch flat is when you run over something with your tire & it pinches the inner tube against the rim causing it to go flat. That's a basic definition. So I guess on an atv its the same principle.

I can give you a visual of exactly why I hate 14" wheels. It cost me two $165 each tires. The only solution I found was to go with a 28" tall tire on a 14" wheel, or ride at a rock hard 8-9 psi tire pressure.
These were my 26.5" Pitbull Rockers on my 850.

 

[gtsum2]

Yep^^^same thing with 26 bighorns on 14 wheels. Not a good combo in rough terrain at all

I'm guessing if you didn't care about fitting on 50" trails then you could still put 12" wheels on if they had enough offset? Or use spacers?

you can force something to fit by changing the parameters IE adding offset, or spacers, but you've also got to consider what these changes do to the geometry of the machine. More stress on wheel bearings, more stress on tie rods, EPS, Ball joints, suspension bushings. Less steering clearance, Less wheel travel clearance. Etc. Etc. Etc.

For spacers you're looking at a minimum of 2"-3" spacers to clear the tie rod.

It's just not worth it. So for the Dual Front A-Arm suspension you're best of sticking with the 14" rims and adding larger tires to avoid pinched side walls.

Note, this may require modifying the clutching, and potentially stronger axles to account for the larger forces required to turn, stop, and steer larger tires.

Yep this is why I run 12" rims on my quad. Learned this lesson on my truck. Was running a 20" rim with 35's but there is not enough sidewall for good impact protection. Went back down to an 18" rim with 35's and has never happened again. I really do like the look of a 14" rim (or larger) but unless you are running a big lift (4"+) or have a side-by-side 12" is the way to go in my book. Just my 2 cents

 

[bp405]

Yeah this doesn't prove anything as far as the 570sp and 12" rims are concerned. It only proves that stock rims don't fit. I'm willing to bet a 4+3 offset on a 12" rim will work on a 570sp.

Also this whole hating on 14" rims is a lack of knowledge and buying into misinformation. First of all 14" rims cause no more or no less pinch flats the 12" rims its the tires that wrap them is where the problem lies. In the off-road community the general rule of thumb is you want a 2:1 ratio tire to rim diameter. If the tire to rim ratio deviates to much from that ratio the user will run into problems. I run 26" tires on 14" rims and it is absolutely the best combo. To crunch some numbers my 26" BH 2.0's measure 26.75" @5psi. So on my 14" rim the ratio is 1.91:1. Don't buy into the misinformation 14" rims work just as good as 12" because there are pros and cons to each and basically the rider needs to make an informed purchase based on his riding style, needs, and environment.

And I'm willing to bet you are wrong. The OEM wheel has a 4+2 offset, and if you look at all the pictures, you will see the wheel is still at least an inch from being seated on the hub. A 4+3 offset gives you one more inch to play with, but it would still be against the tie rod end when fully seated on the hub.
As for 26" tires on 14" wheels being the absolute best, that is crap as well. If you just ride smooth, hard packed trails, I'm sure you would be on the money with that. My alleged "lack of knowledge" cost me $330 worth of tires, riding the exact same trails I had ridden for years with 12" wheels and 26" tires. Never had a flat prior to the two pinch flats, and haven't had one since going back to 12" wheels. Anyone who rides rocks knows the truth about the 26/14 inch combo. It simply is not suited for the job.
They say a picture is worth a thousand words. You have been offered up some 7,000 words worth of proof in this thread that actually, visually, show problems, and yet you continue to deny that the problems are real. If you would kindly go buy yourself a 570 SP and show us all how you fit 12", 4+3 offset wheels on it, then I could eat a helping of crow. Since someone who does actually own a 570 SP showed us all that a 12" wheel doesn't fit, I think my crow dinner is safe.

 

[Guilow]

Here is the clearance on my stock 570 SP. Not much room to go down in size. I'm guessing you'd have to get wheels with a massive offset or something.

So the guys including me that have had pinch flats on 14's and not 12's has no knowledge of this and are giving out false information. I have both sizes and the 14's give me double the trouble as the 12's. Since I don't have any knowledge of this I guess I need to stop posting.

Of course you can change the perameters to make something fit. Make the quad massively wide to allow your 12" rims, Add massive spacers, Etc. You can always find a way to make something work. But at what cost? The SP models have a hard enough time working with aftermarket 14" rims, let alone trying to cram 14" rims on them.
