The Toyota bZ4X spacers provides many benefits for your wheel upgrades. The major function is to push the wheel further out, adding more backspacing and reduce wheel offset. For aesthetic purposes, spacing out your wheels boosts the overall look of your Toyota bZ4X. A vehicle that installs the wheel spacers gets a sportier look. For function purposes, installing wheel spacers helps wheels clear suspension/brake/protruding hubs issues. They also increase the distance between the left wheels and the right wheels, hence increasing the traction. This is effective when your 2022 Toyota bZ4X is driven in bad weather or when cornering. When provided the option of your wheel modifications, hub-centric spacers should always be used. The hub-centric design allows the spacers to sit centered on your hub, rather than dangle off the studs. Most wheel vibrations after installing spacers are exclusively caused by not using hub-centric spacers. (Above photos from www.toyota.com)
What Types of Toyota bZ4X Wheel Spacers Do I Need?
Among the Toyota bZ4X spacers on the market, there are two main types of spacers: slip-on and bolt-on. Slip-on spacers directly slide over the wheel studs and are sandwiched by the wheel and the vehicle hub. Bolt-on wheel spacers are bolted to the existing studs with the provided lug nuts and then secure the wheel on the spacer with the stock lug nuts. When using slip-on bZ4X spacers, it is essential to ensure that there is enough thread engagement left for the lug studs. Since slip-on spacers push the wheels further out on the same set of studs the wheels bolted on, they also reduce the amount of stud left for the lug nuts. As a rule of thumb, you need at least the same amount of engagement as the width of the stud. For example, an M12x1.5 stud would require at least 12mm of thread engagement to be safe. At a thread pitch of 1.5 mm, this equates to about 8 full turns of the lug nut. If you cannot achieve this, you will need to switch to extended studs to ensure safety.
In addition, because the bolt-on bZ4X spacers double the number of studs and nuts per wheel, you need to be extra careful to check that all lug nuts are properly torqued down. After installing bolt-on spacers, it is a good idea to double-check whether all lug nuts are tightened to the manufacturer’s specification with a properly calibrated torque wrench. It is always a great idea to regularly inspect torque specs before and after each trip, regardless if you have spacers or not. Give the spacers another check after 100 miles of driving to make sure they’re still in place well and double-check the torque on all the lug nuts. Spacers have existed around for multiple decades, and as long as they are high-quality and installed correctly, there is very little opportunity for wheel spacer failure.
