Beyond the stock setup, you've got genuine options. Our collection spans multiple diameters and widths, from aggressive 19-inch designs to refined 18-inch alternatives. Whether you're after OHM's precision engineering, KATANA RACING's bold styling, or Petrol's distinctive character, we've matched each wheel to your BMW's specifications with zero guesswork required.
2018 BMW 340i Base Wheel Fitment Guide — What Works & What to Avoid
Your 2018 BMW 340i Base needs a 5x120 bolt pattern and fits 18-inch or 19-inch wheels in multiple widths. Stock specs run 18x8 at plus-34 offset up front and 18x8.5 at plus-37 in the rear. This staggered setup is recommended, though square configurations using 18x8 or 18x8.5 across all four corners also work. Compatible 19-inch options include 19x7.5 through 19x10.25 widths at appropriate offsets.
Since only 5x120 bolts fit this BMW, verify that specification before ordering. The hub-centric bore measures 72.6 millimeters—if your wheel's center bore runs larger, use hub-centric rings to ensure proper fitment. Aggressive wheel widths or offset choices outside the compatible range risk contact with fenders and suspension components, so stay within the listed sizes.
Every wheel in our inventory fits your 340i and ships free to the lower 48 states. You'll find staggered and square setups in stock from Work Wheels, OHM, Heritage Wheel, Niche 1PC, Enkei, Aodhan, Petrol, and KATANA RACING.
