What are the biggest tires I can fit with my setup?

I have a 2012 SV 4x4 CC. I'm putting on the PRG 1.5" lift and doing a decent amount of PWM. I want to buy the Metal Moto MO962 in 18x10 (-24 offset, 4.56 backspacing). I definently want the Nitto Trail Grapplers too, but not sure what the biggest size I can go with and avoid rubbing. Any help would be much appreciated, thanks in advance.

Probably 33's and that's about it. Even then you'll be lucky with a -24 offset.

I appreciate the info. On Nitto's website they offer the following sizes in 18": 275/70r18, 285/65r18, 285/75r18 and 295/70r18. What is the biggest of those sizes that would fit with my setup? Thanks again!
Try a 325/60r18 it'll look baller. Or 305/60r18. Imo the 200 series are too narrow. The 295/70r18 is a 34 x 11. No way you'll fit that.

Only problem is they don't sell the Nitto Trial Grappler mud tire in the 305 or 325, unless I am missing something? I really want to stick with the trail grapplers. The terra grapplers and terra grappler g2's just don't have that aggressive mud tire look like the trail grapplers. If I stick with the trail grapplers i guess I get the 275/70r18's (inflated diameter is 33.62", as stated on their site)? Their site says the 285/65r18's measure 32.83" diameter and the 285/75r18's are 35.08". I'm clueless when it comes to this wheel and tire stuff.
The metric tire size is an equation, not an actual size. Its figured out like this:

325/65R18 - The first number is the width in MM, the second number is the heigth of the sidewall in percentage of the width, in this case, the tread width is 325mm, or 12.79", and the sidewall is 65% of that, so 211.25mm or 8.3 inches. Now to get overall height, you add the wheel diameter (18"), and add the sidewall x 2 (16.6 inches), which makes it 34.6" tall and 12.79" wide.
Thanks, this clears a lot up for me. I might try the Nitto trail grappler 295/70r18's. If I rub, is there something other than a full lift kit that I can add to prevent rubbing? Like further PWM or shocks (hopefully without uca's or expensive uca's at least), I guess the 1.5" prg wont do a whole lot.
2-3/8" in front over stock on an 09 4x4 and a mild PWM and i clear 295/70/18s bump to bump and full turn, However, i'm not sure with that offset. Also, my front bumper has been modded, half the steel is gone, the edges trimmed, and those tin tube supports are removed.

if you're just after the look, then going wider would be alright, but keep in mind that if you're seeking traction off-road, the wider is not better, unless you're heavily into loose sand. if you're just tooling around town in it, then you can probably clear them with just a little bigger spacer on the coils, or mid-5100s and a 1.5" spacer, but if you get flexed out you'll rub pretty bad, most likely. All in all, if you're going for just the look, there won't be that much a stance and visual difference between the 275s and the 295s. the 285/65/18s will fit a post 08 4x4 bone stock, (I ran them for four years before any suspension work or body mods). It depends on form or function what to chance, IMHO, I'd stick with the smaller tires unless you want to add more lift. Listen to pa-pro on this stuff, I once didn't, and it cost me a couple hundred and some major headaches. Good luck.

I think I'll stick with the 275/70r18's just to be safe. The offset is a lot to take into consideration. The wheels/tires are for looks only, maybe later on down the road when I want the bigger lift then I'll go with 35's etc. Ordering the wheels and tires tomorrow, hope it all works out! Thanks to all the input once again.
