Thanks for all the feedback, comments and voting so far.

Here is what I'm leaning towards now. It looks like it should work using the calculator, but, can anyone take me to 100% it will work? :smile (2):

Option 6: the Aggressive Rookie, Deep Concave all around, maximum width in rear
22x10.5 Front +30mm offset on 305/35/22 tire (30.40 inch tire diameter, 42mm more than stock offset)
22x12 Rear +49mm offset on 305/35/22 tire (30.40 inch tire diameter, 42mm more than stock offset)

I am 90% sure the front fitment works (pushes even closer to strut).

I am 90% sure the rear fitment works (pushes closer in the fender).

I am more confident in this setup because it pushes it so far out, inner clearance for any suspension should be fine. But the 10% is again the fender rub.

I'll get photos tonight, I have them, but can't post them at work. With this offset, I don't think 305 would work unless you cut the plastic. The one time the tire rubbed, it hit just the edge of the plastic liner due to suspension arc. If the tire was wider and taller, it would be an issue I think. I do like the look of the rim being pushed out though; I hate the tucked in look. It's never going to be like my old IS350 where I rolled the fenders, ran a 245 on a 10" rim, and still rubbed everywhere I went. But the FX is much more practical.

Thanks for sharing shadow. Wow +25mm offset, that's 47mm more than stock. That will clear suspension for sure=)

285/35/22 is 11.22inches wide vs 305/35/22 being 12 inches wide. It's also shorter by .55 inches.

Do you have any photos?

Can you go any wider for the rear tire?

Good question. I want to stick with Pirelli (thanks Pierce), so my options are:

Pirelli Scorpion Zero Asimmetrico 420 A A Z (All Seasons)
  1. 265/40/22 Front = 30.7" diameter, 10.7" wide, good for 9"-10.5" wheel width (tirerack, discounttire)
    305/35/22 Rear = 30.6" diameter, 12.2" wide, good for 10"-12" wheel width (discounttire)
  2. 305/35/22 Front and Rear = 30.6" diameter, 12.2" wide, good for 10"-12" wheel width (discounttire)

Pirelli PZero Nero 220 AA A Z (Max Performance Summer)
  1. 265/30/22 Front = 28.3" diameter, 10.7" wide, good for 9"-10.5" wheel width (tirerack)
    315/25/22 Rear = 28.2" diameter, 12.4" wide, good for 11"-12" wheel width (tirerack)

So basically I can get .2" wider, probably not even noticeable.

Maybe a shorter tire will help? That will leave me to go Pirelli PZero Nero setup. Speedo would be off, so that might be annoying though. I have a winter setup, so summer only tire is fine, except the 220 tread wear rating makes it one expensive, short lasting, tire.

What's the point of having a wider rear wheel if you are going to run the same sized tires all around? Isn't it going to look odd to only have the rear tires flush with the wheels and a 1/2" bulge in front? Seems like the opposite of what would look "normal"... :dontknow:

Tire bulge difference won't be that noticeable as it's made to fit with a 10-12" wheel width. 10.5" vs 12" bulge on a 305/35/22, I am anticipating you won't notice.

The 12" rear is for a more extreme concavity, as it will concave more than a 10.5" due to wheel width.

Point taken, but not concerned about how the tire looks, as the tire choices I have chosen do not offer extreme bulge or stretch.

I guess you do have to think about the tire more, since the wheels are lipless. It would be obvious if you had a 2" front lip and a 5" rear lip..., but with full face, you have to look at concave.

And to be honest, I have no idea how much more extreme concave the 12" rear is, as I haven't even seen a 22x12 F14, even online.

I see what you're after. If you're right about the bulge difference not being noticeable than Opt. 6 gets my vote. :tup:

sorry man, been so tied up no time to even get to a pc past few days :)


I agree with tchuck, I too would be concerned about the tire visual... with a tire that's good for a range of 10" to 12" wheel, on a 10" rim it will have significant bulge, where same tire on 12" rim will have no bulge... I'm sure it wouldn't look horrible but it will be noticeable & not ideal. personally I would really avoid 1.5" rim width difference with the same tire front & rear...

far as fitment, I have an 11" with +48 offset. I'd say that at a standard dropped spring height with the stock suspension I could get another ~11mm towards the outside & ~15mm towards the inside as max, so that would equal a 12" wheel at what would equate to a +50, so your +49 is right there, should work out fine & be at max fitment... you will probably have to roll the inner lip of the quarter panel & trim the wheel opening molding but that's really no big deal...

in my opinion wheels this wide will not be so hot in the winter months with snow & & ice anyway, so I'd suggest the max pef summer tires that you picked & to use a set of winter wheels...

I'd also suggest that 28.2" overall diameter is over 2" shorter than stock, might pay to look into my tires, they will fit better at being 29" diameter & give you a little more side wall, my sizes are 265/35 & 315/30, that's a little more meat than 265/30 & 315/25.... not saying the pirelli's aren't good, just that the advans will be a better fit & they are awesome tires too, there max perf summer tires but there also a sport truck tire which gives a bit more load rating and they will also wear less than the pirellis, with a UTQG of 320 A A vs. 220 A A. from my experience with pirelli's they do wear out quickly compared to many others... for some reason tirerack don't list the 315/30 22 anymore in the yoko advan st. but I'm pretty sure there still available... going from a 30.4" diameter to a 29" diameter is a big difference, going down to a 28.2" is going to be even more severe...

One of the offset gods have spoken.... (the other being Viet).

Thanks. Time to think about it and let it sink in now...

That information is as good as gold to me. Just thought I'd point that out.

With that information, anyone should be able to estimate the right offset for any wheel setup.
 
Forgestar F14 FTW.

Ive got them on my 350z and love em. Concave 19x10 and 19x11 look sweet. Just make sure you get the right offset to get that flush stance. Full concave!
 
Can't really see a good close up of those wheels and the pictures that do have a good angle of the wheels are too small yo get a good view, lol.
 
Really need you guys help here....im getting 22 for a 05 fx35 and i wanted to know if it possible to fit 285 45 22 tires on them and if they'll rub when i turn

What is the width of the wheels? For good fitment for that tire size, the width should be 9-10 inches. Depending on the tires brand and the amount of sidewall bulge you should not have any issues with rubbing.
