Genesis tire sizes

We cover 4 Genesis models across 9 factory fitments, spanning model years 2019 to 2024. The size that turns up most often on a Genesis is 225/45R18, followed by 225/40R19 and 255/35R19. Wheel diameters run from 18 to 20 inches, so the trim and wheel package matter as much as the model year.

Genesis does not stamp an approval code on tires the way Porsche and BMW do, so any tire in the right size that meets the load index and speed rating on the door placard is a legitimate replacement. Pick on wet braking, tread life and price instead.

Pick your model below to see the size for every year and trim, what it costs from budget to premium, and which tires are worth buying in that size. If you already know your size, search by size instead, and if you are not sure where to find it, our guide on reading a tire size shows exactly where the placard sits.

Genesis is Hyundai's luxury brand, split off as its own marque for the 2017 model year and now selling roughly 60,000 to 70,000 vehicles a year in the United States. The lineup is the G70, G80 and G90 sedans and the GV70, GV80 and electric GV60 crossovers. Its reputation is built on equipment levels and warranty rather than on badge history, and the cars are engineered with German sedans as the target.

That target shows up directly in the tire fitments, which are staggered in a way no Hyundai is.

Tires on a Genesis

Genesis stamps no approval code on its tires, so there is no equivalent of BMW's star to look for and the door placard is the full specification. What Genesis borrowed from the German sedans instead is staggered fitment: a G70 2.0T runs 225/45R18 front and 255/40R18 rear, the 3.3T moves to 225/40R19 front and 255/35R19 rear, and a G80 3.5T Sport runs 245/40R20 front and 275/35R20 rear. Buying four identical tires for one of those cars is the most common Genesis tire error, and it also means no front-to-rear rotation and rears wearing out roughly twice as fast.

The crossovers are square and simpler, a GV70 on 235/55R19 and a GV80 on 265/50R20. Wheel sizes are large for the segment from the start, with 19 inch the base on most trims and 20 inch common, and the 35-series rear sidewalls leave little protection against potholes. Original fitments are usually Michelin or Continental grand touring tires, and because these cars are heavy and quiet, owners who replace them with a cheaper touring tire usually notice the road noise before they notice the grip.

The models that matter

The GV70 and GV80 are the volume models, on 235/55R19 and 265/50R20. The G70 is the one to watch for staggered sizes, 225/45R18 with 255/40R18 on the 2.0T and 225/40R19 with 255/35R19 on the 3.3T. The G80 runs 245/45R19 on the 2.5T and staggered 245/40R20 front with 275/35R20 rear on the 3.5T Sport.

What owners find out later

Both G70 engine options are staggered, but they are staggered in different sizes, so a 2.0T and a 3.3T of the same model year share no tires at all. The rear-biased staggered setup means the most economical purchase on a G70 or a G80 Sport is a rear pair, and a shop that quotes four is not reading the placard. Most Genesis models carry a compact spare rather than a full-size one, and on the staggered cars that spare is narrower than either fitment.

Because the brand is new, some tire retailers' fitment databases still file these cars under Hyundai, where the sizes listed will be wrong.
