The R34 GT-R uses equal wheel and tyre sizes on all four corners. Owners commonly stay with 18-inch wheels, moving from the factory 9J width to 9.5J wheels in either a conservative or lower-offset fitment.

Quick specs
Nissan Skyline GT-R R34 / BNR34 hub and fastener specifications
BBS lists this wheel specification for the BNR34 and specialist fitment guides use this tyre size. Check the wheel's Brembo clearance and the arches at the intended ride height.
Nismo explicitly lists 9.5J ET12 for the BNR34, with this reference tyre size confirmed by its retailer and owner examples. The lower offset needs careful arch and camber checks 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
Use four matching rolling circumferences for the ATTESA four-wheel-drive system. The factory and listed aftermarket configurations are square.
Brembo clearance depends on spoke shape as well as wheel diameter and offset. Check the exact wheel application, particularly on cars with larger brake conversions.
No wheel nut torque is populated: online GT-R tables contain conflicting numbers and some purported R33/R34 manuals describe later or non-GT-R cars. A correctly identified factory manual is needed.
Nissan's factory table states a 66 mm hub hole; aftermarket fitment catalogues usually call this 66.1 mm. The manufacturer figure is retained here. Buy hub rings by the confirmed BNR34 application and actual wheel bore.
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.

5x114.3, with M12x1.25 wheel nuts. Nissan lists a 66 mm hub hole; the aftermarket commonly describes the fitment as 66.1 mm.
What are the original R34 GT-R wheels?+
18x9 ET30 with 245/40 R18 tyres on all four corners.
Will 18x9.5 wheels fit an R34 GT-R?+
Yes. BBS lists ET30 and Nismo lists ET12 applications. The lower-offset option needs more attention to arch clearance and alignment.
Should an R34 GT-R have wider rear tyres?+
The original setup is square. The listed alternatives also keep matching tyres on all four corners for the four-wheel-drive system.

66 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.
