Are there any issues with installing 20mm wheel spacers?

[Quintero]

Installing 20mm wheel spacers does come with certain problems. Here are the impacts of adding wheel spacers to tires: 1. Damage to axle shafts: While driving on smooth roads may be fine, driving on uneven roads will cause more severe vehicle jolts, which can damage the universal joints of the axle shafts. 2. Impact on wheels: The quality of wheel spacers varies greatly. If a spacer gets damaged, it can affect the original vehicle wheels, often leading to deformation or even breakage. If a wheel detaches from the vehicle body, serious accidents may occur. 3. Tire wear: One of the purposes of vehicle suspension tuning is to reduce abnormal tire wear. Adding spacers changes the wheel track, which can cause abnormal tire wear. 4. Fender rubbing: The vehicle should not be overloaded, as mentioned in the third point, because it can lead to abnormal tire wear and sometimes even cause the tires to rub against the fenders.
