Tire placement on the 50" RZR

From a relatively new sxs rider and even newer here on the forum, I need at least 2 inches clearance on my RZR and don't really want to get into a lot of mechanical modifications.  Never was one for mods with my style of riding.  I raised the Rubicon and the Grizzly with tires and it seemed to really work out well.

I plan to raise the RZR the same way with 27" Swamplite or some other affordable tire that runs taller in size and maybe a stronger set of shock springs.  Here is the question, What are the thought on here of running the same size on all four corners.  The 9" on the front are adequate, just the 27x10x12 all the way around are my thoughts.  The trails are not near as narrow as they used to be and those roots don't jump out as often and grab the wider front tires as they used to.  I also plan to install 1" wheel spacers as soon as I widen the barn door.
There is probably more RZR riding experience on here than anywhere I can think of and I know the comments will be helpful.    Please...MD

When I had my 800 50" I put 26" bighorn 2.0's on it with a set of ITP wheels(can't remember which type they where) but I had to buy 1 1/2 or 2" wheel spacers to get the right rear to clear the motor mount. If I bottomed it out pretty hard the right rear would rub the exhaust also. The fronts left would rub when I was turn sharp left and hit a bump, didn't to it turning normal but if the suspension got compressed while I was making a hard left. Hope this helps you out.

Cale, Thanks for your comments.  I did some looking and visual measuring and didn't see any thing that jumped out at me that might rub.  But you have given me a place to start looking more pin-pointed.

Mine has the Polaris mag type LE wheels and when I was looking, I kind of figured the 27x10x12 might be to full to run under the front fenders, but was not sure.  I guess I should have asked "what is the tallest tires that will run under the stock 50" RZR with factory shocks and springs set at mid-point."

Good information, my pad is out...MD

Mike if you go 10" all around put 4+3 offset rims on it

 Yep, Timmi and Cale, I went back out and did some closer looking.  I will have to spread it out to get much larger tires on it, maybe more than I will want to.  I may have to raise it up with the 2" lift kit and drop back to a 26" tire.  I don't know how I missed that engine mount on the right rear, it is kinda close to the stock tire as it sits.  I probably won't change the rims from the stock ones.

Back to the drawing board.  Maybe the 2" lift and the heavy duty springs will be the way to go.  Then match up a tire that will fit...MD

Mike, if you put a lift on it, the tire will be even closer as it pulls the a arms in. a 10" wide with stock rims is the max. most 27" are 11" wide on the rear

 Ok, lets back up.  If I put the 2" lift kit on I won't need to put the 27x10x12 all around.  The lift kit and the heavy duty springs will give me the lift I need for the rocky trails. 

Then I will have to decide on the size of tires to go along with the 1" wheel spacers.  I may have to stick with the 25" stock size tires. 

This RZR stuff is all new to me and I have a lot to learn, while trying to not have the bank in mods etc.

Thanks for all the information, I just have to have time to process it all and figure out another way to make the lift happen.  I have got to get it up at least 2 inches or I am going to lose interest in it.  I'm riding normal trails at CAW and hitting rocks and dragging the bottom on the normal everyday ruts etc after even trying to dodge a lot of them...MD

There is lots of info on here if you dig for it about the Zuk LT front shock swap, and I forget what they were running on the rear, but it was way affordable and gave 2" of lift and a way better shock. If it were mine and I was on a budget, I would do that and a set of 26x9 original Bighorns all the way around with spacers if you like the wheels you have now.

Or you could just go ahead and drop some $ on a set of Elkas and be done with it. If you ride hard, the Elkas are worth every single dollar that they cost.

I have a set of shocks, LT450 and YZ125 that I got from finzup. It's going to require a lot of work to install them on my 570 in the rear but they are bolt on for the 800.  :)

  As I understand, the shocks alone will provide the needed 2" lift and give a better ride.  At that point, will i still need at least 1" wheel spacers to spread it back out a little?  If so, tires can then be just a matter of selecting the size that fits.  Am i correct now in my thinking?

Thanks for the patience as I learn...MD

I think spacers are pretty much a must to put any tire bigger than stock on it. When I was trying to figure out what tires/wheels to put on mine some one on rzr forums told me that what I wanted would work with out spacers but they where wrong. I was so mad because I got them and went to put them on and the right rear hit that motor mount, so I had to order and wait on the spacers.

  Thanks Cale, Timmi, and Hump for the enlightening information.  It is a little more complicated than raising the Grizzly a little bit to me.  I am a little hard to learn, but once I get it, I keep it.

My plan was to install the 1" wheel spacers regardless of anything else I did anyway.  I actually didn't know that the shocks upgrade would physically lift the RZR 2".  This puts a different light all together on the situation.

SO, having said that, Timmi, will the shocks you have give mine the full 2" lift?  AND, how do they measure up to the other shock upgrades...MD

Running 450 shocks on front,with rzr 800 rear springs, super atv 225 rear springs on stock shocks on rear with lift, 1.5 spacers. Perfect for me. Just need jbs skids now.

Mike, I don't know how much lift exactly because I never got them installed. I do know these shocks are a bit longer than oem so there is no way I could use them with the 2" lift I have.
I can install the fronts as others have said, since the 570 and 800 are identical in the front.
The ride improvement is night and day from oem since these are all reservoir shocks.
Keeter has a similar setup but he has heavy duty springs on his.
I do know with these shocks and one inch spacers you can run 27" tires, I have seen it on several 800 rzr's.
James has the wheel spacers.

I don't run lift on front just rear, shocks are longer to give lift on front

the YZ125 shocks are longer than oem. I can measure them to see how much. There are several threads all about this topic on rzrforums.

I'm happy with mine now,12 front 11.5 rear clearance no sway bars rides nice for me.

James(JBS) use to sell a bracket to mount the yz shock on the rear I think. You might give him a call and see.

I sold Timmi his shocks and ran them on my 800 50" with good results.  Also have had 1-1/2 spacers all around for many years with 14" Crusher wheels and 26" tires.  Unless you have power steering, low speed steering effort goes up with bigger tire patches.  JMHO

  Thanks for the continued comments.  I have so much information now, it will take a day or so for me to process this great information.  But I feel I have enough options to make a more informed decision.  I really don't mind spending, I just don't want to double or triple spend.

Finzup, your information about the heavy duty shocks and springs with the wheel spacers and the tire size you ran is very informative.  Maybe that engine mount won't be too hard to overcome after all.

Thanks again for all the information...MD

Whatever you do, go with those shocks instead of a lift kit. You will gain travel, height, better ride, and speed.

I wish I had researched more before buying a lift and bigger tires. I achieved the ground clearance I needed but it rides like crap.

Timmi I notice you said the YZ shock was longer and I wanted to know if you meant longer than your rear shock as on the 800 the rear is longer than the front shock.

Keeter, when I had your rear shocks they were the same length as my 570. Maybe that was because it had highlifter springs on it? the yz shock is longer than the 570 rear, about 1 1/2"  if I remember.
Do the people who use the yz shock on the rear have to modify the mounts? I understood they were bolt on ready.
I can measure them if I can think to do it when I get home.
Seems like the fronts are 16" on both machines.

There's a template to download from Timmi's forum reference to redrill the lower, rear shock mounts.

oh so the rear shocks are not bolt on, interesting. I never read that whole thread since it was so many pages. I didn't think there was enough space on the lower shock mount to make another hole.
the problem on the 570 is the yz reservoir hits the frame so the top mount must be moved out which means the rear stabilizer bar must be removed.

U need to junk those swaybars anyway timmi, if u want the nice ride.

the front one is disconnected.
without the rear it sways like a sail boat
too unstable for me

That's probably the stock springs to soft, without bars.

if I tighten the springs it rides worse. I can't bring myself to drop big bucks on shocks.
just gotta live with it until I can afford a 900 s
