The 2022 BMW i4 wheel adapters can not only give you the proper spacing but also convert the bolt pattern to adapt a variety of aftermarket wheels. The hub side is machined to fit the OEM vehicle hub, and the other side is built to the wheel specification. For instance, a 1-inch 5×112 to 5×120 wheel adapter makes it possible for a 2022 BMW i4 to install 5×120 wheels meanwhile push those wheels out 25mm. The vehicles become more stable as the 2022 BMW i4 wheel adapters provide additional width for the wheel track. In this way, the weight of the vehicle is distributed on all the wheels equally which in turn improves the comfort of car handling. The adapters are approximately 1-2″ thick depending on the wheel gap and offset. When shopping for a set of 2022 BMW i4 wheel adapters, the guide below may help you.
Methods to Measure 2022 BMW i4 Wheel Adapters
Purchasing the correct 2022 BMW i4 wheel adapters is important to safely install the wheels and save time & budget. Generally, as long as your vehicle’s bolt pattern is 5×112, and the wheel’s bolt pattern is 5×120, you can use a 5×114.3 to 5×120 wheel adapter. If you get several hand tools, we highly recommend you do some ground job, such as measuring the actual PCD, CB, thread pitch, rim pocket depth, stud length, and fender gap. The correct PCD (bolt pattern), CB (center bore), and thread pitch ensure a perfect fit.
The bolt pattern refers to the diameter of an imaginary circle formed by the centers of the wheel lugs. You can simply check your car’s year/make/model, then search the result on an authoritative website. But different wheels come with different types of bolt patterns. Common bolt patterns are of 4, 5, or 6 lug holes. In a 5-lug wheel, measure from the back of a hole to the center of the second hole. To measure a 4 or 6 bolt wheel, you need to measure center to center of two holes directly across from each other.
The center bore refers to the diameter of the hole in the center of the vehicle hub and wheel. If the size of the hub bore is different from the wheel bore, even they are the same bolt pattern, they won’t match. To measure this, measure from one side of the center hole to the opposite side, as the diagram shows.
How Thick 2022 BMW i4 Wheel Adapters Do I Need?
The rim pocket depth and fender gap determine how thick the 2022 BMW i4 wheel adapters will fit properly. Technically speaking, the minimum required thickness is about 25mm. Most wheel adapters are bolt-on types. These adapters are fastened on the vehicle hub with special shallow-head wheel bolts. In most cases, you can remount the wheels on the spacers with original equipment wheel bolts.
Take a look at the inside of your wheels and measure the cavity in your wheels to check out how much it will allow for the bolts to go past the spacer outer surface. Giving an example, if the depth of the wheel pocket is 8mm, and the head of the bolts protrude 3mm, then any size bolt-on wheel adapters will recess all the lugs in it, so you have no rubbing problems. If the cavity is not deep enough, then changing to thicker spacers will be OK.
The second factor is the wheel gap. Take a straight edge and place it against the outermost part of the rims/tires, then measure from the outside wheel to the fender line to see how much space you have available. Repeat this on the front and rear wheels and you’ll soon get a feel for the size of the 2022 BMW i4 wheel adapters you require. For instance, if the value is 25mm, then it is recommended to 25mm adapters.
