2005–2014 · saloon
The second-generation IS left the factory on staggered tyres, with wider rears even on the 17-inch wheels, and the IS F added forged 19-inch BBS wheels with a wider rear rim. Owners chasing a flush look usually run 19s at around ET35, while IS F track builds favour wide square 18s.

Read these before choosing wheels for the IS / IS F: they explain the offset, fitment and hub numbers in this guide.
Starting points for a build. Read the notes with each setup, especially if your car is lowered or has different brakes.
ClubLexus members advising an IS 250 owner on F Sport springs recommend ET35 all round on 19x8.5 front and 19x9.5 rear wheels with 235/35 front and 265/30 rear tyres, without fender work. Members on lower-offset or wider rear setups report rubbing.
IS F owners on ClubLexus run 18x9.5 ET45 all round, with 275/35 R18 described as the best daily size. One owner on 285/30 R18 track tyres reports very tight clearance. Not every 18x9.5 ET45 design clears the IS F brakes; one member says Enkei RPF1s do not.
A ClubLexus member reports another IS F owner running 275/35 R18 tyres on 18x9.5 ET40 wheels without much trouble. It sits 5 mm further out than the ET45 option.
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 IS / IS F. Try the wheels, colour and stance before you spend on parts.

These tools start with the IS 250 / IS 350, 17-inch alloy front size. Choose your own trim or axle in the calculator if it differs.
5x114.3, with a 60.1 mm centre bore and M12x1.5 wheel nuts tightened to 103 Nm. The IS F uses the same mounting.
19x8 ET45 with 225/40 R19 at the front and 19x9 ET55 with 255/35 R19 at the rear, on forged BBS wheels.
It depends on offset and tyre. Owners suggest about ET35 with a 265/30 R19 to avoid fender work; ET25 or lower with a 275/30 tends to rub, especially lowered.
Yes. Owners run 18x9.5 at ET40 to ET45 with 275/35 R18 tyres, but the wheel design must clear the IS F brakes, which some 18-inch wheels do not.
Factory tyre (tire) sizes for the 2005–2014 Lexus IS / IS F XE20 are 225/45 R17, 245/45 R17, 225/40 R18, 255/40 R18, 205/55 R16, 225/40 R19 and 255/35 R19, depending on trim, with wider rears on staggered setups. Your tyre placard shows the size for your car.
60.1 mm. Aftermarket wheels with a larger bore need hub-centric rings sized to it.
103 Nm (about 76 lb-ft) for the original nuts. Confirm in your handbook, especially with aftermarket wheels or nuts.
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.
