So I am getting an Ace. I also have a couple of RZR's. There seems to be a good amount of used or take off tires and wheels available on the web.

Stock RZR 50" wheels and tires:
Front 25 x 8-12; Maxxis
Rear 25 x 10-12; Maxxis

Stock RZR S wheels and tires:
Front 27 x 9-12; Maxxis Bighorn
Rear 27 x 12-12; Maxxis Bighorn

Stock RZR XP900 wheels and tires:
Front 27 x 9-12; Maxxis Bighorn
Rear 27 x 12-12; Maxxis Bighorn

All are available on the Crusher aluminum wheels. Does anybody know which tires will fit and which would be best? Are 27" too big? I think some of the RZR S tires are actually 26"'s. Pictures?? Thanks

Taller tires will diminish it's power.

Totally True--I have 26 on my ACE and now I am going back to 25s

I have the stock RZR 50" Maxxis 25 on my Ace. I ride mostly on dirt or gravel. The top end speed is still there with these tires. They do a decent job in the mud. View attachment 1236

i put on the rzr black crusher wheels with stock size bighorn 2 tires. fit great and no notable power lost. Unit feels less tippy too (not that it was real bad before) Fits on 50" trails.

Can you elaborate on this a bit?
I am seriously considering going up to 26" tires to gain ground clearance.
How much did you feel the power loss? Why are you going back to 25" tires?

I have 26" tires and have no problems at all, still hit 50mph on them. I think the biggest factor is weight, I looked for a tire that didn't weight too much over stock.

Running 26" Zillas on 14" diesel aluminum rims, lot's of difference in handling but no noticeable power loss. Still hit 50 on open road and a really big improvement in grip in the mud and sand by the river. The weight doesn't seem to affect the performance much but going from steel to aluminum may have made a difference also. I will have to weigh them the next time I get them off for a real comparison. Zilla 26" inch are closer to 25.5" and wider by an inch per tire. I don't think I've gained more than a 1/4" clearance from stock with 8 psi in them.

With BigHorns, there is a noticeable (and BIG) difference in ground clearance between the 25x8x12 and the 26x9x12 on the same wheel. At least 1.5 inches.

But it puts the sidewall VERY close (1/4") to the standoff on the front strut that they put on there to prevent the tire from rubbing the spring. Makes me nervous having it that close. May try another config later, but when I saw that I decided to stay with the 25" for now.

So the 12"x 8" Crusher rim fit on the rear of the Ace no problem, no mod with 25" tire?

Think the 12x8 rim would work on the FRONT or would I need a spacer?

 

[Scoundrel]

The 8" RZR wheel will not fit the front of the ACE. The offset is too deep, they will hit the struts.

I am using the six inch RZR wheels. The part I used is the front wheel from the 2010 RZR 800 S.
The eight-inch rear RZR wheels will fit on the rear of the ACE with wider tires, but they'll look a bit ridiculous.
I suggest the RZR front (6") wheels all around, with maximum 26x9x12 tires on there. But you won't be 50" with 26x9x12.
You need to stick with 25x8x12 on that special Polaris offset which I think is 4+2 to stay at 50".
