I did upsize to 245/55/19 on stock rims and there is slight rubbing at full lock, All-in, happy with the size. These are the same diameter as 225/60/19, so either 225/60/19 or 235/55/19 would reduce or possibly eliminate the rubbing.

 

To say you never only means when I read that phrase regarding any vehicle subject ......and to reference several platforms all having different engineering designs for the drivetrain chassis and suspension... lol
Give it time. They do affect the bearing life it just maybe you have not noticed it or have not gone enough miles yet to see the premature wear or failure of them.
I use spacers and have for years but I am realistic when choosing the width. If you cant afford to buy the wheel to give to width of wheel and tire don't cheap out at the expense of prematurely wearing past or possibly breaking them by spacing out. LOL
In many sanctioned road track regulations limit the wheel spacer you can have. maybe they know something about issues with wide one

Now if you want to claim what you do that's fine but unless you are a *Automotive *Engineer then maybe think about what you post? *Someone that is one may read what you state and want to respond with realistic information?

Example of a simple test. Taking an empty bucket with a handle extend your arm while holding it. Now have an assistant add weight. Now think about the result. Or if you are math savvy the formula you need to use is called mechanical load and effect.

 

Funny story. I AM a Mechanical Engineer and have worked for a Tier One Automotive supplier as a Process Engineer. Prior to that as a Six Sigma Black Belt Quality Engineer for Honeywell and Northrup Grumman Aerospace. I now work as a Supplier Quality Engineer for the US Government (DCMA) in Ordinance and Tactical Systems.
I am 63 years old and have been in my field of endeavor since leaving college. As to what you say, it may have validity if we were driving an F1 car or a high stress application but we are talking daily driven street cars here.
Have a great day and quit picking the specs out of the fly ****.

 

As am I. The difference is I engineer and develop Performance parts for vehicles And I wont go into my credentials as many on this forum already know of them and are likely tired of me posting them. LOL. And BTW tossing in your age as if that is really relevant, really LOL does age really matter, SIR? LOL I never post what my age is but those that are fairly intelligent and read my responses can get a general idea! As for your level of education IMHO perhaps if you good at your profession then you may not have posted what you did? LOL Just saying? I also read you other responses and IMHO you are a DIY when it comes to vehicles.
I think it is a bit irresponsible to post things on forums that are potentially dangerous from members and feel compelled when I am responding in a few threads of interest to point out a better thought of the subject.
And usually when I do it's like fishing the members that do post less than the best information often with a response to defend what they posted. LOL
BTW please look at the data and information posted from reputable sources on the broken wheels over decades because of the use or miss use of wheel spacers. Keep in mind before you go off, I never said the small width was part of that only that anyone using them should first find an alternative and not jump at the easy way to add.

 

Dont care.

 

Lets refresh why I responded how and why I did.
The vehicle your signature (RED) is also have listed in your signature as :

You placed it there for members to see. I did and saw you have lowering springs. So in your other response yopu respond and i quote you...."Not one problem to report with bearing attrition or suspension issues.". Did you forget about your lowering spring on your Audi? Lets see the specificaion of those spring are between 1.1 and 2.0 respectively lower then factory ride height. You also increase the load capacity of the springs over Audi OEM to Frt 365lbs anbd R490lbs . And then claim the statement not having any problems ever?
The manufacture does not recommend the use of spacers when using their suspension components specifically the lowering springs.
And under their own Warranty the use of wheel spacers fall under misuse of their product.
I know the company and know their policies very well.
Dude... all my suspension products and even my BBKs I state on the installation instructions in capitol letters in RED WARNING, all ***** (company name withheld for obvious reasons) NOT to use wheel spacers and doing so may void the warranty .

The main reason I am so against the average Joe/Jane DIY using most wheel spacer is that they don't buy quality CNC spacers with quality fasteners and also go to thick. They seldom ever get the proper balancing of the axle when using them and simply do the normal most common tire wheel off the vehicle balance. Ask yourself , does a wheel spacer change the balance of an axel? Answer YUP! The other thing is that earthly event that happens when going into turns call gravity that translates into "G" forces. Suspension will react differently in turns then driving straight with an occasional bump in the road. As speed increases so does the force which compresses the suspension and closes the gap of tire clearance. Then we also have to factor in the "G" force will also distort the tire which can add to changing the clearances as well. Bottom line to sacrifice safety and control of your vehicle using wheel spacers for looks may not be the most intelligent thought and choose? Unless you carefully measure and double check all the clearance issues that may come up while driving.

 

Different stress limits for sure, but the same principles to measure them apply equally to a daily driver as they do an F1 or Peterbuilt truck...

 

 

 

Hahahahaha
The wheel wizard is so good he needs to refer to his notes on the bench...almost as good as those bigfoot videos.
