1995–2002 · roadster / coupé
The Z3 roadster and coupé use E36-era BMW wheel mounting, so a wide range of factory BMW and aftermarket wheels bolt straight on. Most owners move from the 15 or 16-inch wheels to staggered 17s or 18s, and the main question is how much wheel the narrower four-cylinder rear body will take.

Read these before choosing wheels for the Z3: they explain the offset, fitment and hub numbers in this guide.
Starting points for a build. Read the notes with each setup, especially if your car is lowered or has different brakes.
Owners on ZRoadster.org fit the BMW 7.5 and 8.5-inch staggered 17s to cars that came on 16s, including four-cylinder narrowbody cars, without spacers. One 1.9 owner says the 245/40 rears fill the arches better than the standard rear wheel.
A ZRoadster.org thread covers fitting E46-size 18x8 ET40 front and 18x9 ET45 rear wheels with 225/40 R18 all round, and an experienced member confirms they fit. The high rear offset leaves room for a spacer to bring the rear out.
Check the exact setup
There is no confirmed range for this car yet. Compare a known wheel with your proposed size and measure both sides.
Measure before ordering
A maximum width has not been confirmed. Tyre shape, ride height and alignment all change the available space.
These figures belong to the setups described here. Combining the widest wheel with either end of the offset range does not guarantee a safe fit. For how ET moves the wheel in and out, read wheel offset explained; for how far the tyre can sit out, see flush, poke and tucked fitment.
Upload a photo and start with a look that suits the Z3. Try the wheels, colour and stance before you spend on parts.

5x120, with a 72.6 mm centre bore and M12x1.5 wheel bolts, for roadster and coupé.
Owners report that the factory 17x7.5 ET41 front and 17x8.5 ET41 rear, on 225/45 R17 and 245/40 R17 tyres, fit narrowbody cars without spacers.
225/40 R18 keeps the rolling diameter within about 1% of the factory 225/50 R16, and owners use it on 18x8 and 18x9 wheels.
The mounting is the same, 5x120 with a 72.6 mm bore and M12 bolts. The staggered 17x7.5 ET41 and 17x8.5 ET41 sizes match the Z3's own 17-inch option, but check offsets on other designs against the arch limits above.
Factory wheels are 16 × 7 inch, 15 × 7 inch, 17 × 7.5 inch and 17 × 8.5 inch, depending on trim. The stock table lists the offset for each.
72.6 mm. Aftermarket wheels with a larger bore need hub-centric rings sized to it.
This guide is a starting point, not a fitment guarantee. Specs can differ by market, trim and previous modifications. Confirm all sizes, clearances and fastener requirements with a qualified wheel and tyre professional before buying or fitting parts.
