Sounds like an urban legend.
To: MeneMeneTekelUpharsin
Never mind the possibility that people who put 20", 22", or 24" rims on their cars also tend to drive more aggressively, perform burnouts, and generally drive their vehicles harder.

Every (well, ok, most) offroader knows this. If you increase the weight/size of the wheels, you have to beef up the axles and other driveline parts to handle the strain.
Where the OP falls down, is in assuming that those larger rims increase the overall diameter of the wheel. There are idiots who run cartoonishly-large wheels on passenger cars, and yes, there will be an increased rate of failure in driveline parts as a result, but the number of people who do that is extremely small. If you run correspondingly-lower profile tires so you maintain the same (or very nearly the same) diameter, then the effect is negligible. At worst, you might be increasing rotating mass very slightly, which could add a little strain.
The real killers are deeply-offset wheels (stick way out past the fenders) which destroy wheelbearings, and the ultra-low profile tires which beat up your suspension.

Nonsense. Overall diameter of the tire and wheel is all that matters and there is very little room under the fender well to put anything much bigger.

I would posit that the tire circumference and width have more to do with accelerating mechanical wear than diameter of the rim.

To inform the public, it is known among auto industry experts that oversize rims, 20", 22" and 24", etc. eventually destroy transmissions, clutches, seals and axel bearings, etc. due to the torque factor required to turn those. If you reduce the sidewall height on the tire at the same time, the diameter and circumference of the total assembly remains the same.
In some cases, very low profile tires are used to put visual emphasis on the larger wheel, and the total diameter/circumference is actually smaller. This is the equivalent of raising the final gear ratio.
This is basic geometry.
Of course, the sidewall reduction has side effects (no pun intended):
- The sidewall doesn't flex, and the car usually responds more quickly to steering input.
- The lack of sidewall flex is detrimental to the ride, as the tire cannot absorb as much shock from encounters with potholes, expansion joints, and other irregularities and hazards on the road.
- The tire is more vulnerable to failure after encountering the same hazards. A sharp edge on a pothole can pinch the sidewall against the wheel and puncture it. These are usually not repairable, and the entire tire must be replaced.

My registered, professional, mechanical engineer husband says this is true. They also destroy the suspension.

Hogwash. Torque in the driveline is determined by the engine output and the transmission/rear axle gearing. not by the wheel size.
OTH, in order to fit on the car, the OD of the tire must stay roughly constant. This means as the wheels get bigger, the volume of air in the tires gets less. It is this volume of air that helps isolate the car from the road. This means that the wheel will experience more contact directly to the tread from pot holes and bumps. This leads to rim damage, and higher impact forces to suspension parts and into the chassis. This can lead to some of the types of damage you listed.
Let the buyer beware. It has nothing to do with the car when you install parts for which the car was never designed.

Yes ma’am. However, by the few posts already put here, we see the disinformation and propaganda put out by someone with an agenda. This country is steeped in lies and corruption.

If you run correspondingly-lower profile tires so you maintain the same (or very nearly the same) diameter, then the effect is negligible. It seems to me that you introduce a different tradeoff--you get better handling, but you work the suspension harder because there's less give in the low-profile tire walls.

t = F x r. Basically the larger the radius, the more force it takes to turn the wheel, the inverse of the crowbar effect. Not like most of the idiots who waste their paychecks on rims and wheels would get that.

The rims and tires are part of the drive train design. When you alter that with oversize rims/tires, everything (effective torque) changes and the speedometer/odometer becomes inaccurate!
