Which brand should you pick?

Alfa Romeo does not stamp its own approval code on tires the way Porsche or BMW do. Any tire in the right size that meets or exceeds the load index and speed rating on your door placard is a legitimate replacement, so pick on wet braking, tread life and price. Our picks for each size are on the size pages below.

The drawing carries the sizes we list for this car, so you know what you are looking for. The placard on the car is still the final word, and it is the only place that gives the cold pressures: the number molded into the sidewall is the maximum the tire can hold, not what your car wants.

Alfa Romeo Giulia tires: common questions

What size tires does a Alfa Romeo Giulia take?

The most common original size is 225/45R18. Other model years and trims use different sizes, so check the list on this page and confirm against the sticker inside your driver's door.

Can I fit a different size on my Alfa Romeo Giulia?

You can, within limits: the overall diameter should stay within about 3 percent of the original, and the load index and speed rating must meet or exceed the door placard. Anything further changes your speedometer reading and can rub at full lock.
