Mercedes-Benz A-Class W177 wheel fitment
The W177 A-Class ranges from 16-inch wheels on basic models to 19-inch AMG Line and A35 packages, all square front to rear. Most upgrades are 18 or 19-inch wheels at a similar width and offset to the AMG Line wheels, and A35 owners need to watch brake clearance.

Explained in our guides
Read these before choosing wheels for the A-Class: they explain the offset, fitment and hub numbers in this guide.
- Wheel offset explained: choosing ET without guessingUnderstand positive and negative wheel offset, calculate inner clearance and outer position, and choose an ET using measurements from your own car.
- Flush, poke and tucked fitment: measure the whole tyreUnderstand flush, poked and tucked wheels, calculate how width and offset change the look, and check clearance beyond a parked side-on photograph.
- Hub-centric vs lug-centric wheels: choosing hub ringsLearn what hub rings do, how to specify their inner and outer diameters, and why centring, wheel seats and vibration need separate checks.

18-inch lightweight daily
- Front and rear
- 18 × 8 inch, ET45 · 225/45 R18
BBS lists several 18x8 designs between ET41 and ET52 for the AMG Line. The factory 225/45 R18 keeps the original rolling diameter.
A35 19-inch forged
- Front and rear
- 19 × 8.5 inch, ET38 · 235/35 R19
BBS lists 19x8.5 ET38 forged designs for the A35 as tuner sizes. This keeps the factory A35 tyre size and sits slightly further out than the 8x19 ET40 original.
Width and offset guidance
Offset range
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.
Common width limit
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.
Clearance notes
- Genuine AMG Line 18-inch wheels are listed as not approved for AMG Performance models such as the A35. A35 brakes need wheels approved for that model.
- Genuine A35 19-inch wheels (8x19 ET40) are sold as A35 fitments.
- Fitment databases give a 66.6 mm centre bore and BBS Japan lists 66.5 mm on one OE-style wheel. Use hub rings for any aftermarket wheel with a larger bore.
- Factory bolts are M14x1.5 with a ball (radius) seat. Tighten them to 130 Nm on dry threads, and use the bolts specified for any aftermarket wheel.
- BBS Japan marks some sizes as tuner sizes, which may need body changes depending on tyre size, tyre brand and ride height.
- Genuine AMG 18-inch wheels for the hatchback are also listed for the V177 saloon.
- Check full steering lock and suspension travel with the car loaded. Match wheel load rating, tyre load and speed ratings, fastener seats and brake clearance.
