22x9.5 +20 Offset Fitment Question

Hows it going guys,

Im new to the forums so before i ask, just wanted to say that this forum is awesome and i see myself looking through the forums on a daily basis. Some really nice rides here without a doubt hence i drive my 1st gen FX with pride hoping it can look like some of them one day...one day. But to address my question (apologize in advance if this has been asked before i swear i couldnt find any info) i was planning on purchasing a new set of 22 inch rims and was wondering if i will have any fitment issues with a TSW wheel with specs: 22"x9.5" offset +20. I am lowered with h&r springs. Will i need to shave or trim my fenders and also what tire size would you recommend (im thinking 265/40/22 but need some advice to get a warm fuzzy feeling about my purchase). Also i live in pacific NW and the roads are shit, so do you guys think 22s will be a bad idea as far as rim safety and overrall comfort? Thanks in advance for your help!
 
265/40/22 's will give you almost same overall tire height as your OE tires thats why I went with that size. I am running 9 in width with a +15 offset and H&R springs with no rub issues whatsoever. So I think a 9.5 width may work with a +20 offset ok. Anyone know if +5 offset more would equal 1/2" more tire width?
 
MTN,

If your running 9x15, the rims with 9.5x20 inner clearance should be 11mm less and the outter face sould sit 1mm out more right? Did you need to trim or shave your fenders? and would 285/35/22 tires be a better fit as far as worrying about rubbing?
 
That wheel and tire set up should be fine. I ran 22x9 +15 and 285/35-22s for a while, a lot of the Axis Orden set ups are this config or oem height 265/40-22 size tires.
 
Depends on the tire shoulder and how much camber you end up with. 285/35-22 will have a slight bit more bulge then a 265/40-22 but the 285 is also shorter. 265/40-22 is a safer size to run.

Same spec wheels with a Toyo tire.

Right now, I'm running 22x9" +25 in front and 265/40/22 without rubbing. In the rear, I have 22x10.5" +25 w/ 285/35/22 and no rubbing but the fender is slightly rolled/trimmed. My car is pretty low now though, ~1 finger gap front and rear. But it's only been this low for a short time, I was dropped on H&R's for a long time and no rubbing in the back even before I rolled the fender. A 22x9.5" +20 in front will fit nicely, but in the rear it will look sunken. Once I get some other stuff finalized, I'm putting a 10mm spacer on the back so it will be a 22x10.5" +15 offset and based on measurements, that should clear fine w/ the rolled fender.

9.5" +20 offset would retract the wheel by 1mm based on Rookie's 2 pics above. IMO thats pretty flush - but maybe im wrong...

But a 10.5" +15 offset would push the wheel above by almost 0.75" inches! that seems too much don't you think?

Instead of 9.5" +20, what do you guys think of 10.5" +35 offset on all fours? Kind of curious if anyone is running the 10.5" +35 set up on all fours (pics are greatly appreciated). I'm just worried about clearance issues on the inside of the wheel
 
285/35-22 on a 10.5 is a shorter then oem tire, and 285mm tire on a 10.5" wheel. The pictures above show you tire is flush, not the actual wheel lip. Which is what I mentioned earlier it will depend on the side wall bulge you end up with. 265 on a 9 is fine and should be the safest for fitment.
 
That picture is deceptive. If the car were lower, the wheel would tuck more. It would still hit if you didn't trim the rear quarter, but it would tuck. I just got back from messing w/ my ride height. When the car is lowered to less than 1 finger gap, the tire is almost tucking at +25. There is room for a 10mm spacer, but it would hit unless your fenders are rolled or trimmed pretty flat. I'm about to roll my fenders a bit more before pushing the wheels out a bit.

I think a 10.5" +35 would be fine in the rear. There's a lot of room on the inside. But on the front, it will likely stick out. My 9" +25 is already a tiny bit past the fender (camber keeps the tire inside). A 10.5" +35 would be another ~8mm or so further out. So unless you want to stretch a tire, it may not work. A 285/35 isn't really a stretch, but it keeps the tire profile rounded on a 10.5" and since it's shorter than stock as rookie said, it would look better in front.

I just saw a 2nd gen FX today w/ 24"s and the wheels were a good 2" past the fenders at stock ride height. Don't be that guy.

I just bought some wheels and I' trying to figure out if they fit OK.
Wheel specs:
Width: 9.5"
Diameter: 22"
Offsets: +25mm and +40mm

Tires specs:
265/40/22 or 285/35/22(IDK which one will work better, but I'm getting a good deal on 285/35 tires right now)

I will be running the Motorsport-Tech adapters, which are 19mm thick(minimum thickness). Based on my calculations(hopefully I done them right) the new offsets will be +06 and +21mm.
Using the 1010 Offset calculator, I'm getting these results:

Compare to Stock 20" 8" wide Wheels:

+06mm Offset Wheel:

Inner Clearance:
15mm MORE
(the inside of the wheel to the strut housing)
Outer Position:EXTEND an extra 53mm
(position of the outside edge of the wheel)
+21mm Offset Wheel:
Inner Clearance:
THE SAME
(the inside of the wheel to the strut housing)
Outer Position:EXTEND an extra 38mm
(position of the outside edge of the wheel)

My question is, will this setup fit on the FX lowered with coilovers OK?
Thanks in advance.:smile (2):
 
So the front is +6 and the rear is +21? The rear is fine at that width and 285 tires; you will have to trim the wheel wells if you haven't done so. I'm at +25 on a 10.5" and 295/35 tires and minimal rubbing. Wheels wells have been rolled flat and the bump hammered down a lot. It rubbed a ton when I had 305/35 tires. When I had a 285 tire on there and the fenders rolled flat, it never rubbed. Here's something I learned; if you're low enough, you have to roll the fenders well past the 2 bolt holes on top of the wheel liner. That's where everyone says to roll or cut it to, but that was back when people ran just Eibach's. If you slam on coilovers, you'll rub on the metal well beyond that point.

I'm thinking the front will rub some. I'm running +20 now on the front in 9" w/ a 265/40 tire and it rubs on some dips. My tire is ~1/2" from the wheel well, can't fit a finger in there. You can't do much to the front fenders so I had camber set at ~-2 to help some. Still rubs, but much better than before. If you had a 285 tire, you'd rub even more. It's shorter than the 265/40, but since you have coilovers, you'll likely lower it more to compensate and eliminate wheel gap. The 285 would stick out ~10mm more assuming same brand tire. 10mm is a huge difference when you're rubbing.

I'd recommend the 265/40's for less headache. I know they're going to cost you more, but rubbing is really irritating. I hate going tense every time I approach a pothole or bridge junction. There's not any damage, but it sounds horrible and makes the car feel less luxurious. The only reason I deal with it is that I'm still working on a solution and it looks nice.

Thank you very much for the info. My rear trim is already cut:smile (2):, will need to roll the fenders and buy some 265/40 tires then.

PS What about 265/35/22 tire, the difference is 3.97%. Is it safe to run this tire?
 
Your speedo and odo will be off, but it won't cause any issues w/ the AWD since there's no difference in diameter front to back. I run staggered on AWD without any issues. You might just have to lower it a tiny bit more since the tire will be shorter and the wheel gap slightly greater.
 
Thanks again. I found some 265/35/22 Pirelli tires for a good price locally. Now I'm thinking what tire size will work better, 265/35 or 265/40, with my weird offsets?
 
The only issue you may have with the 35 series tires (other than speedo being off) is that you will have to drop the car more to eliminate wheel gap. I guess you don't have to, but it will look funny if you don't compensate for the smaller tire by dropping more. If the roads where you are are really bad, it might cause problems. Where I live, the roads are decent and I still scrape my GT Spec lower tie bar sometimes. I also scrape my lower front bumper very rarely. Once I solve the rubbing issue, I'd like to go another inch down which will cause more rubbing. The 35 series tires will be almost an inch shorter than the 40's. So if your car is half an inch lower and then you drop it another half an inch to compensate for wheel gap...That inch can make a difference if you're already low.

If you can do the ride height, there wouldn't be any issues I can think of. 265/35 is still a thick enough tire that you don't have to worry about wheel damage. I used to run on 225/35/20 on my Lexus (bent 3 wheels in under 2 years). Current BMW I just got has 285/25/20"s; I'm a little nervous about those.
