18-inch daily OZ fitment
- Front and rear
- 18 × 8.5 inch, ET55
An owner documents OZ Alleggerita HLT wheels in this size for daily use with good clearance. A tyre size is omitted because the cited build does not identify it.
2010–2016 · three-door coupé
The Mk3 Mégane RS uses high-offset factory wheels and a 5x114.3 hub. Wider aftermarket wheels are well documented, but rear arch clearance becomes sensitive to offset, tyre shape and lowering.

Starting points for a build. Read the notes with each setup, especially if your car is lowered or has different brakes.
An owner documents OZ Alleggerita HLT wheels in this size for daily use with good clearance. A tyre size is omitted because the cited build does not identify it.
The community guide pairs this with about 2 degrees of negative front camber. Other owners report rear rubbing on bumps, even with narrower tyres and lowering springs. Rear arch clearance must be assessed; this is not an unconditional direct fit.
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 Mégane RS. Try the wheels, colour and stance before you spend on parts.
