Mazda RX-8 SE3P wheel fitment
The RX-8 uses equal wheel and tyre sizes on both axles. Owners commonly retain 18-inch wheels or move to lighter 17-inch sets for track use, while the R3 has factory 19-inch wheels.

Explained in our guides
Read these before choosing wheels for the RX-8: 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 wider road and track setup
- Front and rear
- 18 × 9.5 inch, ET38 · 255/35 R18
Enkei lists this RC-T5 fitment with 255/35 tyres. An owner also reports this size on Mazdaspeed springs and Bilstein B8 dampers without rubbing; check clearance for the actual tyre and ride height.
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
- Mazda’s owner instructions give 88–118 Nm. Mazda TSB 02-002/04 specifies 147 Nm as part of a repair for snapping noise with certain original 18-inch wheels. These are different applications, so no single torque is supplied for every RX-8; check whether the bulletin applies to the car and wheels.
- The manufacturer’s original tyre specification for the 16-inch package is 225/55 R16. Do not substitute a different profile from a generic size table.
- Seventeen-inch brake clearance is design-specific. The cited RPF1 fitment does not establish that every 17-inch wheel will clear.
- The R3’s 19-inch wheel is ET47, rather than the ET50 used by the common 18-inch package.
- 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.

Questions
What bolt pattern does the RX-8 use?
5x114.3, with a 67.1 mm centre bore and M12x1.5 wheel nuts.
Can I use 17-inch wheels on an RX-8?
Yes. The documented 17x9 ET45 RPF1 is one example. Check brake clearance for the exact design.
What tyres fit a common 18x9.5 RX-8 setup?
255/35 R18 is documented with 18x9.5 ET38 wheels. Suspension and arch clearance still need checking.
Why do RX-8 wheel torque figures differ?
The owner instructions give 88–118 Nm, while a Mazda service bulletin specifies 147 Nm for a particular original-wheel noise repair. Use the manufacturer instruction applicable to the car and wheels.
What wheel size does the Mazda RX-8 SE3P use?
Factory wheels are 16 × 7.5 inch, 18 × 8 inch and 19 × 8 inch, depending on trim. The stock table lists the offset for each.
What is the Mazda RX-8 SE3P centre bore?
67.1 mm. Aftermarket wheels with a larger bore need hub-centric rings sized to it.
