Vossen wheels on an X5M? Need Help please

[reihani]

Fellas,

I have a very limited knowledge base when it comes to wheels. Want to change from the stock X5M rims to vossen CV5 or CV3 wheels, that would mean a change in wheel size of 20" to 22".

Are these wheels of high enough quality to go the M? and is it really a disadvantage if its not "forged" both in terms of safety and ride? I also can't find any info on how much these wheels weigh, but the increase in 2" size would probably mean a weight gain.

I would also like to get rid of my RFT. Any tire recommendations (All seasons) would be much appreciated.

Thanks for helping this noob

The problem with these cast wheels, like almost all cast wheels, is they don't go any larger than 11", so you can't get the ideal staggered size of 10.5 front and 12 rear in a 22" set. I believe cast wheels just aren't strong enough to go 12" wide.

u have to go to a square set, i think vossen 22s are 10.5 wide

Vossen are one of the better cast wheels out of the market, they should be strong enough but keep in mind the weight of a 22 inch cast wheel will be so substantial that it will have an impact to performance

[reihani]

The stock x5m wheel is 11" wide in the rear and vossen has the cv3 in 11" but only for the 20" wheels. So 10.5" in the front and 12" in the back is the ideal/recommended size for 22" wheels?

Any recommendations of forged wheels that aren't too pricey?
Any thoughts on 23" Hamann wheels? I'm thinking 23" will be too big plus tires that size are difficult to find.

Stock wheels are cast wheels, too, so the weight isn't the issue. It's the available width. Look at rennen wheels and call Eric at nitrous garage. They are a forum sponsor, and they give discounts to forum members. The prices are pretty reasonable for forged wheels. Not much more than the higher end cast wheels.

Tell Eric I sent you. They sold me my winter wheels and the service and communication is outstanding.

[reihani]

As far as fittment goes, would you recommend 12" in the back and 10" in the front for a set of 22's?? Really torn between cast or forged.

[upstate650]

10.5 front on 22"

[reihani]

Neither the cv5 or cv3 are offered in 22x12. Any thoughts on Vorsteiner or Pur wheels? any recommendations?
cheers

Hamann makes some really nice 22s, that's what I went with...check it out.

IMO Forged is the way to go if you can afford it. HRE makes some outstanding forged wheels: expensive and not everyone's taste but a top quality wheel.

Now, 22s look great but have you thought of all the headaches that come with them? Additional expense now and later; limited selection and expensive tires that wear out much sooner than smaller sizes; balancing and alignment issues and finally the additional weight that compromises ride and handling. Your car is going to feel like it has 4 anchors. Of course it is your car and it looks like you are all set to go through this "upgrade" so my comments are irrelevant.

[upstate650]

Forged 22's weigh a lot less than the stock cast 20's. Why do 22" tires wear out quicker than 20's. What balancing and alignment issues? Your comments aren't irrelevant, but I'm not sure they are accurate.

Yes, you would think if the tire is the same and the compound and wear ratings are the same then it would make no sense that the bigger tire would wear any faster. The same for balancing and alignment issues. I'm just speaking from my own personal experience after "upgrading" several cars over the years. Another upgrade I would recommend against is the aftermarket exhaust for "better" sound: it is cool for a while until you grow tired of the constant droning and frankly just the annoying noise the thing makes.

If you are in your twenties then you must go through all of these upgrades like I did. I did it all: bigger wheels, suspension, exhaust, turbocharging . . . . you name it. Good luck with your choices and I still recommend forged wheels if you can afford them

OK. A quality exhaust system doesn't drone. Going to 22" tires from 20" really aren't bigger, in the applications used on X5's, which is what we are discussing - the circumference is virtually identical. 22" tires are no more difficult to balance than 20's and the size of your tires, which again really isn't any different than 20's, has nothing at all to do with the alignment of your vehicle. I think you may be confusing these issues with lowering a vehicle, which can affect tire wear and alignment if camber is not handled correctly.

Not in my 20's, or 30's, but not dead yet, either.

I'm not in my 20s either and I have a full turbo back exhaust system and I have no drone at all. There are many exhaust designs for different applications and if people make the right choice for their needs then people wouldn't complain so much. Just my 2 cents.

You know, in looking at this a little further, going with forged wheels, even taking into consideration a size increase from 20-22" saves you around 10 lbs per wheel. Going to the Pirelli scorpion 22" tires everyone uses on that setup saves another 10 lbs per wheel over the stock run flats. So rather than 4 anchors, you are LOSING 20 lbs of unsprung weight AT EACH CORNER which is a HUGE amount!

Even if you go with a cast 22" wheel, the weight increase is offset by the significant weight savings of the non-run flat tires. And there is exactly 4 revolutions per mile difference between stock tires and the Pirelli 22's.

You're definitely on to something but I'm pretty sure that the anchors he's referring to has something to do with rotational mass which is different than weight. If someone else who knows this stuff could chime in. I'm not exactly sure why but I read somewhere else that it's the increase in mass going to 22s that will still make your car feel "slower" even with weight savings. Then again, I read that a while ago so I could be completely wrong too lol

They are different, but closely related. Has to do with how far the weight is from the center of rotation. Regardless, the weight savings is so vast, and the diameter of the wheel/tire combination doesn't change, so either way, there will certainly be no anchor effect.

I am contemplating the same...want to go to custom wheels. Dont want to spend 6K on them. Like the Vossens: actually probably going to get CVT for my S(audi).

Cant decide if I should stay with 20s and use the RFTs(have a lot of thread left in them) or go all out and get 22s with Pirellis...decisions....LOL.

[reihani]

I can't seem to find cast wheels with 12" for the rears.

[stlcity]

This might be an option..think price wise it is in the same range as Vossens

I'm looking to probably get it also. Not too many options out there specially since I am looking at 22".

Our new VF series using a flow forming technology will have 12" widths offered in many applications and arrives later this year

Wheels are all about quality like any product. Not all forged wheels are amazing just because they are forged and not all cast wheels are bad because they are cast.

We offer a high quality "cast" wheel and owners around the world (we are sold in over 38 countries) feel the same way.
