Does anyone know if these wheels are any good ?

It doesn't say anything about what the offset is.
You sure you want 7's on the back?

I did have an idea to run the same size tyre front and rear

That sounds fine. A lot of people are doing that.

I think as is we basically have 6s front and 7s rear now so 7s all the way around will be fine. Pretty sure the rears aren't 8s but might be wrong. That +10 is the offset. There are two ways they show offset. The first is actually a worldwide metric standard of where the mounting surface and the wheel center is offset. The other is a traditional terminology of how many inches it sets in from the mounting surface and how many sets out from the mounting surface..ie 4+3, 4+4,5+3...ect  I'll see if there is a conversion chart somewhere for this +10

Ok, found a calculator and that +10 is a 4.39" backspace. So that's close enough to mean those are a 4+3 which is kind of a standard offset.

Nice one, is the pcd right for the zforce ?

What does "pcd"  stand for? If you mean offset, its fine.

Think he's talking about "pitch center diameter" ....distance between lugs.

Oh, ok then if that's it then yes, the CFMotos have the 4/110 pattern.

Thank guys, I was thinking about fitting 10" wide tyres front and rear what do you think ?

Anything can be done but just to make you aware..... wider tires will grab groves much more than the narrower tires.  On the rear this is no problem because its non steering.  The front can be pulled around.  If your UTV has power steering then there shouldnt be a problem at all.  But without it there can be issues.  I have seen guys break hands/thumbs from this when hooking a rock/tree with wide tires and it spins the wheel.  Im not saying its something to be scared of but if you DONT have power steering and you want wide tires keep a FIRM grip on the wheel and dont ever drive with your thumbs inside the loop of the wheel.

Fortunately these have rack and pinion steering so with or without P/S won't be much of a problem on front but yes, do except some additional bump steer. The other thing we discussed in another thread was weight distribution. Remember the bulk of the weight on these are on the rear tires so the contact patch will have more weight per square inch then the front. With all four tires the same the handling and tire reaction characteristics are going to be different. Without testing it is only a guess but you may experience not only uneven traction front and rear...ie less up front and more in back, but tire roll-over in back on slides even with increased air pressure. Pure speculation for the CFM though but I have seen it on other machines.  Just wanted you to be aware. There is more reasons why the differences in tire width then may be realized. 

The guys i have seen have problems also had rack and pinion ....it still happens

Yep. Just not quite as bad.
