Alfa Romeo tire sizes

We cover 5 Alfa Romeo models across 7 factory fitments, spanning model years 1981 to 2024. The size that turns up most often on a Alfa Romeo is 225/45R18, followed by 245/35R19 and 285/30R19. Wheel diameters run from 14 to 19 inches, so the trim and wheel package matter as much as the model year.

Alfa Romeo 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.

Alfa Romeo is the Italian sports brand inside Stellantis, back in the United States since 2008 after a long absence. The current range is the Giulia sedan, the Stelvio crossover and the smaller Tonale, and annual US volume is under 10,000 vehicles, which makes it one of the smallest mainstream-priced brands here. The reputation rests on steering feel and on the Quadrifoglio performance models rather than on service intervals.

There is also a substantial classic following in the US for the Spider and the GTV6.

Tires on a Alfa Romeo

Alfa Romeo does not stamp its own approval letter on tires, so unlike a Porsche or a Mercedes there is no code to match, and any tire in the correct size, load index and speed rating is a legitimate replacement. The volume fitments are straightforward: a base Giulia runs 225/45R18 all round, and a Stelvio runs 235/60R18 on base trims or 235/55R19 on the Ti. The Quadrifoglio models are where it gets expensive, because they are genuinely staggered at 245/35R19 front and 285/30R19 rear, so a set of four identical tires is the wrong order and rotating front to rear is impossible.

Those cars also leave the factory on a summer tire with no all-season option, which catches out buyers in snow states. Wheel sizes have grown the way they have everywhere, from 14 inch rims on the 1980s Spider to 19 inch on a current Stelvio Ti. Owners of the ordinary cars mostly move to a good all-season, while Quadrifoglio owners tend to stay on a max-performance summer tire and add a separate winter set, usually one wheel diameter smaller to get sidewall back.

The models that matter

The Giulia and the Stelvio are effectively the whole US business. The Giulia takes 225/45R18 in base form and 245/35R19 front with 285/30R19 rear as a Quadrifoglio. The Stelvio runs 235/60R18 or 235/55R19.

The classics still on the road are the 1982 to 1993 Spider on 185/70R14 and the 1981 to 1986 GTV6 on 195/60R14, both easy sizes to buy today as modern radials.

What owners find out later

Most Giulias and Stelvios ship with no spare tire at all, only an inflator kit, so a sidewall cut means a tow rather than a roadside change. The staggered Quadrifoglio fitment means the rears wear out first and the wear cannot be evened out by rotating, so replacing a rear pair while the fronts still have tread is the normal outcome. Alfa's thin-spoked 19 and 20 inch wheels take more balance weight than usual, which is worth knowing before you accept a diagnosis that a wheel is out of round.

On the classics, the original Spider and GTV6 sizes are still in production as modern radials, which is not true of every period Italian fitment.
