Questions on 22x12(F) Offset & Tire Size For Wheel Experts

First off, I appreciate any help any of our wheel experts can offer. I am looking at picking up a second set of wheels and converting my 742 over to a Winter wheel with Scorpions. The size I am thinking is 22x10.5(F) and 22x12(R). I would like the wheels to be flush with the fender, but not poke. I want to go as concave as possible on the front and a super deep concave on the rear. I know people are going approx +35 up front with 22x10.5 wheels. As noted, I want the rear to be super deep concave. I know people are using an offset near +28 on a 22x11.5, so with a x12(R) that should mean an offset near 21 or 22.

I am hoping to get some PS4 tires on the wheels, but sizing is the complicated part. They have a 335x25 22 for the rear which I am sure will fit well. The front gets more complicated. They make a 295x25 22 and a 315x30 22. I am concerned about very little sidewall on a 25 with local roads, but not sure the 315x30 will fit a 10.5 wheel well.

So here are my questions...

- Are my calculations for 22x12(R) +22 right for the rear?

- With that (R) offset, will the 335x30 fit without poking out?

- Can I fit a 315x30 (F) on a 22x10.5 +35 without poking? Can I even fit that 315 on the front and get it to look ok or am I going to be forced into the 295x25 or 285x30 if I want PS4.

Thanks for the help.

EDIT: I have added the rolling diameter of stock and some of the Michelin PS4

Stock - 275x35 22 is 29.6"
Stock - 315x30 22 is 29.4"
Michelin PS4 - 285x30 22 is 28.8"
Michelin PS4 - 295x35 22 is 27.8"
Michelin PS4 - 315x30 22 is 29.5"
Michelin PS4 - 335x25 22 is 28.6"

A rear size of 22x12 +21 or +22 will definitely poke. That's an extra 31mm than stock. My opinion is that an offset of +30 or +31 will be flush on the 12" wide wheel.

I'm not sure if you're aware that the width of 315 is stock on the 10.5" wide OEM 742M wheel. So it will fit no problem, even on the 30 aspect ratio. As far as 10.5 +35, that will definitely fit without poking out with the 315.

Ok, so I went the wrong direction in my offset. Good info on the offset.

I am just curious if the 315 is too much tire for a 10.5? It also makes the diameter of the tire notably different than the rear. The stock difference is only like 0.2”. The 315 would increase that difference to 0.9”. That seems like a lot?

Regarding offset, stock is 9.5 et37 front..... and 10.5 et43 rear. I'm running 15 and 20mm spacers respectively, and I believe I have as close to "flush" as possible with no "poke".

The "equivalent" to that would be 9.5 et22, and 10.5 et23... let's call that your starting point.

I would NOT go with a full 0.9 difference in rolling diameter between the front to rear wheels. However, going down 0.9 rolling diameter on all 4 wheels isn't a big deal. The worst that will happen is that your speedo might be 2 or 3 mph off. Basically, negligible. If anything, it will raise the overall gear ratio a little bit, and help improve some low-end torque/acceleration that you lost by installing heavier wheels. That's exactly what I did. I would try to stay no more than 0.4 difference between front and rear rolling diameter though. I know you really want to run the PS4s, so my recommendation, based upon the tire sizes available, would be:

Front: 285/30/22 (28.8 rolling diameter), on a 10" wide wheel, with an et28
https://www.willtheyfit.com/index.ph...=10&offset2=28

Rear: 335/25/22 (28.6 rolling diameter), on a 12" wide wheel, with an et42
https://www.willtheyfit.com/index.ph...=12&offset2=42

My only question to all of this.... is "how high" of an et can you go on the rear.... before you start rubbing against the inner fender?

The answer? Is.... I have no idea. That is precisely why I didn't dictate to Vossen what I wanted my ETs at.... but rather let them use their expertise to determine the best fitment for me. I have no idea what those ETs will be until my wheels show up, but I trust Vossen isn't going to steer me wrong. I've seen pictures of my exact wheel sizes installed on an F15... and they didn't look "pokey" at all. In fact, if anything, I may even run a small spacer. Considering I'll be lowering my car a bit.... I may HAVE to run a small spacer in the rear., just because I'm running such a wide tire.

I've already done all these exact calculations on my wheels (22x10.5, 295/30/22 / 22x12, 335/25/22) that in order to get the "exact" same external "flush" appearance that I have now, the wheels would have to have ETs of 35 and 42 respectively. Now, I don't know what Vossen will set my ETs at until they arrive, but I can make an educated guess on how much "poke-age" they will have before I even install them, based on those numbers.

As a contrast, Dubsd runs a 22x10 et21, and a 22x11 et18.....That means, his wheels poke out 7.5mm more than mine in the front, and 8.5mm more in the rear.

Another fellow Vossener! Which model did you go with? I placed an order for the HF-5's about a week ago.

I, unlike, you did decide to select my own offsets, and I chose the following:

22x9.5 +18
22x11 +21

I'll be using the OEM tires on the new wheels and will be throwing winters on the OEM 742Ms!

Indeed I went with the HF-2s (in satin bronze) for a couple reasons: Because IMO the bulky X5 needs a busy, chunky, complex wheel..... otherwise, I think it looks "top heavy".... and secondly, they remind me of the Snowflake wheels used on the 1977-1980 Pontiac Trans Ams.... one of my favorite cars of all time, of which I've owned/restored/rebuilt 6 so far in my life

I have an "idea" of the offset I want.... but I wasn't able to find any definitive info on the massive rear wheels and tires I wanted (22x12 with a 335 tire)..... so I decided to let Vossen choose the offset. I didn't want to risk giving them too high of an offset, and end up rubbing the inside of my fenders. Vossen will tuck them in as much as possible, and I can always run a spacer if I want a bit of poke.

My OEM 21s already have all-seasons on them... and will stay that way. I have a new set of Vrederstein Summers sitting in my garage waiting for the new wheels to arrive. The original Continental Summer runflat 21s are in my basement.... with about 300 miles on them..... and I hope I never have to put those Piece of shits back on the car... lol.

The HF-5s are a great design.... very similar to the oem21s. For example though, the HF-1s would look terrible on an X5, because there just isn't enough "meat" on them. Just my opinion. Your sizes and offsets will have an almost identical appearance to dubsd's car... which will look great...... so long as you lower it. If you leave it at stock height, it's going to look like a roller skate though.

I'm waiting to install my BBM droplinks until my wheels show up. They were shipped last friday, which was almost exactly 8 weeks from the date I ordered. Pretty excited to receive them.

Sweet man! Hopefully they choose the right offsets.

Yes I think I'm a few mm less aggressive than dubsesd's offsets. I ordered BBM links and they will be going on around the same time as the wheels.

914, I'm just curious, would lowering via links (for car with air suspension) and installing new wheels/tires require wheel alignment?

No.... all lowering links do is "trick" the suspension into thinking it's riding higher than it actually is. They provide no structural or mechanical support whatsover.... I thought the same thing when I first started researching. When I read the word "link", I automatically associated them with swaybar endlinks. Absolutely nothing alike.

They basically just serve as an adjustable electronic height sensor. With adjustable drop links, you can lower 2mm.... or 60mm.... or anything in between. the choice is yours. Unlike springs on a traditional suspension, where you are "stuck" with whatever height the spring manufacturer intended. All they do, is tell the computer what height to set itself at. The oem ones are cheap, brittle plastic. They don't actually physically support anything.

In fact, I think (not 100% sure) you can even lift the suspension with droplinks if you wanted to..

I guess if you really wanted to..... you could raise 3 wheels and lower the 4th.... and ride around on 3 wheels like a 63 Impala in Compton..... lol.

Anyway..... completely adjustable.

Now..... if you absolutely "dump" the car 4 inches so it's sitting on the frame.... then yes, you'll need an alignment, and your car will ride like crap. But, if you're just lowering an inch or so.... no alignment necessary.

Just to further clarify..... once you set your droplinks to lower the car 1-inch (as an example, because that's about what I'm expecting to do)..... then all 5 of your settings will be exactly 1 inch lower than they were before..... if that makes sense?

I drive with sport suspension (-1 from center) 99% of the time.... so I'll use that as a baseline, and set the suspension where I want it at that level.

But, my low setting (-2 from center) ... and all 4 of my other settings...will also be 1 inch lower.

If I set the suspension right on top of the tires in comfort (center) mode..... then when I drop it to it's lowest setting, I could end up smashing the fenders if my wheels are wide.... so discretion is a must.

Does all that make sense?

I've already done all these exact calculations on my wheels (22x10.5, 295/30/22 / 22x12, 335/25/22) that in order to get the "exact" same external "flush" appearance that I have now, the wheels would have to have ETs of 35 and 42 respectively. Now, I don't know what Vossen will set my ETs at until they arrive, but I can make an educated guess on how much "poke-age" they will have before I even install them, based on those numbers.

As a contrast, Dubsd runs a 22x10 et21, and a 22x11 et18.....That means, his wheels poke out 7.5mm more than mine in the front, and 8.5mm more in the rear.
It really is going to come down to whether I think I would be happy with the Vredestein 295x30 on a 22x10.5" or drop to a 22x10" with the 285 for the PS4.

Have you received your wheels yet? I am curious how your traction will be with the Vredestein tires. Noise level. Maybe that will help me make my decision.

This will be my Summer setup, so I can run down my Bridgestone on my 742 then change to Winters before I would have to decide in the Spring for my new wheels. There may be more options by then? Tough to decide.

I drive with sport suspension (-1 from center) 99% of the time.... so I'll use that as a baseline, and set the suspension where I want it at that level.

But, my low setting (-2 from center) ... and all 4 of my other settings...will also be 1 inch lower.

If I set the suspension right on top of the tires in comfort (center) mode..... then when I drop it to it's lowest setting, I could end up smashing the fenders if my wheels are wide.... so discretion is a must.

Does all that make sense?
Thanks again. Your explanation is very clear to me. I was just curious about this and now wished I got air. I have the M adaptive suspension so will need a spring if I decide to lower the car and as per my research may need wheel alignment after lowering. Appreciate your inputs!

It's a stark trade off. The air suspension is too floaty for me, but I love the ride height adjustment and the comfort. The M suspension is more sporty, but static.

Have you received your wheels yet? I am curious how your traction will be with the Vredestein tires. Noise level. Maybe that will help me make my decision.

This will be my Summer setup, so I can run down my Bridgestone on my 742 then change to Winters before I would have to decide in the Spring for my new wheels. There may be more options by then? Tough to decide.
I haven't received the wheels yet. I'm in Belgium, so it's going to take a while before they arrive. I'll certainly provide a review on the Vredersteins when I get them mounted, but based on everything I've read, they are a great tire. Looking at them in my garage, they appear to be a great tire. I've examined them quite closely. They are made in the Netherlands (not China), and are very popular high-end tires here in Europe.

I'm quite certain they aren't as sticky as PS4s though, and in your case, knowing that PS4s are what you want, I would just stick with the PS4s on 10 wheels.... and not have to worry about running different tires on the rear vs. the front.

That's a fair assessment. I chose the air, because the roads in Belgium are the worst I've ever seen.... in the 45 states and 30+ countries I've visited. For me, it was a necessity. Even still, I drive in Sport Individual 99% of the time, with suspension in sport, and everything else in comfort. It doesn't bother me, and I enjoy the comfort.

I did notice.... on the autobahn..... my car starts getting squirrely around 140mph. Up until that point it's fine..... but at 140, I start to feel uneasy, even in a straight line. With standard suspension, or even the dynamic handling package, I imagine it would be much more steady at higher speeds.
