The Lexus IS is the brand's sport sedan, competing against the BMW 3 Series and Mercedes C-Class with a sharper, more driver-focused character than the Lexus GS or ES. The IS 500 F Sport Performance with its naturally-aspirated V8 is a proper performance sedan. Tire choice should match that character: precise, communicative, capable.
Lexus IS tire sizes by trim
The IS 350 F Sport and IS 500 share the same staggered F Sport fitment: 235/40R19 front and 265/35R19 rear on 19-inch wheels. The IS 300 runs a non-staggered 235/45R18.
The current IS generation (2021+) refreshed the sizes. Verify your exact year and trim on the driver door sticker. Sizes vary significantly between trims.

Should I run summer or all-season tires on my Lexus IS?
It comes down to how you drive it. If the IS is your year-round car in West Georgia, a sport all-season keeps most of the grip while staying safe through cold snaps, when summer tires go hard and lose traction. If you've got a performance version that mostly comes out in warm weather, dedicated summer rubber rewards you with sharper grip. Just don't run summer tires through winter.
How do I know when my IS needs new tires?
Do the penny test, and pay attention to how the car feels in the rain, since wet grip fades before the tread hits the legal limit. If your IS runs a staggered setup, check the rears separately because they wear faster and can't be rotated forward. Watch for cracking, and don't ignore age even when there's tread left.
