Explained in our guides
Read these before choosing wheels for the RX-7: 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.

A second-generation owner reports using this square setup. Confirm arch and strut clearance, particularly on lowered cars.
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
- The primary boltPattern entry covers five-stud FCs. Early base/SE versions use 4x114.3; count the studs before ordering.
- FC-specific database and owner measurements give a 59.6 mm hub. Broad RX-7 charts sometimes quote the FD's 67.1 mm; do not use that as the FC hub-ring size.
- The 1990 Mazda owner manual gives 90–120 Nm. Some online fitment guides quote 115 Nm; retain the manufacturer's range rather than a single torqueNm value.
- Four-stud and five-stud wheels are not interchangeable. The popular examples describe five-stud cars.
- Convertible and market-specific 15-inch wheel widths are not listed where an exact factory package was not established.
- 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.
