Wheel fitment guide
When it comes to replacing stock wheels or rims of 340, every car owner has to deal with some fitment issues. You may run into this question each time you decide to change the wheel size or buy new rims because the stock ones made you feel bored.
Bolt pattern of your BMW 340
BMW 340 Pitch Circle Diameter (PCD) defines the diameter of the imaginary circle drawn by the centers of the wheel lugs and describes the number of the lug holes incorporated by the rim. How to change bolt pattern? Use Adapters
Stock Wheel Offset
What is the stock wheel offset? The space between the hub mounting surface and the wheel center of BMW 340 wheels. If you need a different offset use Wheel Spacers (Amazon link)
Generally, a good half of OEM wheels are correctly fitted only for certain cars, so be attentive! If you want to check out your BMW 340 offset, you have several options – look at the wheels` back, on their mounting plate, or on a rim spoke`s back. And in case you see the inscription that ends with “ET” you are in the right place. This BMW 340 wheel spec may be printed as both “number+letters” or vice versa.
Center Bore (Hub Bore)
The hole in the middle of a rim that exactly matches the hub diameter. It is located at the back of the wheel and as the car's hub goes into this hole it ensures the wheel gets centered correctly. Stock 340 wheels have a perfect centerbore fit with the hub. How to fit rims with a larger centre bore? Use Hub Centric Rings (Amazon link).
Custom Offset Range
It is calculated from the data of modified BMW 340 that switched to custom wheel size preserving the proper driving capabilities of the vehicle.
Lug Nuts size (Amazon link). Measures the thread diameter, the thread pitch, and the thread length. In the metric system, the diameter of the thread, the first digit, is described in millimeters.
Rim Sizes Range

BMW 340 FAQs

What other rims will fit a BMW 340?
Actually, it's not hard to determine whether the BMW 340 tires and rims are a perfect match. You have to look at wheel diameter and width for the ideal fitment. To make life easier, you can find stock rims size and wheels measurements on this page, manufacturer manuals, or the official BMW 340 website. Also, note that the width of the wheel could give you some flexibility, while the diameter is a bit more strict wheel measurement.
Does rim width matter for tires?
The BMW 340 rim width has a significant effect on the tire size you can put on, and if the tire is set on a narrow rim, it would be more narrow as well. So, the wheels size could also change during the fitment. However, the actual tire width may vary. A high-quality tire is able to get stretched up to 5 mm.
Will my car go faster with bigger wheels?
No, wheels with bigger diameters are heavier, and your car's acceleration efficiency may be slightly compromised. The BMW 340 wheels size may also enhance stability when cornering. The bigger wheels, the more stable your car would be, and for that reason, the braking distance will also shorten.
Do bigger rims affect gas mileage?
Yes, wheels with a wider width and bigger diameter inevitably increase the momentum. Thus, your BMW 340 is to consume more fuel because the engine will have to produce more torque. Moreover, unless the larger wheels are lightweight alloys, fuel economy will drop considerably because of upsizing.
