Ford Fiesta ST tire size

Original tire sizes for the Ford Fiesta ST, model years 2014, 2015, 2016, 2017, 2018 and 2019. Trim levels and wheel packages change the size within the same year, so confirm on the door-jamb sticker before ordering.

Front and rear Same size One size fits all four corners on the fitments we list.
Wheel sizes 17" Every fitment we list uses this diameter.
Tire sizes listed 1 One size per model year across the years we cover.

Check before you order. The surest answer is the tires on the car right now: the size is molded into the sidewall. The placard inside the driver's door tells you what the factory fitted. Our guide on reading a tire size shows exactly where to look.

Which brand should you pick?

Ford 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.

Every US car built since 2003 carries this placard. It also gives the pressures, which the sidewall does not: the number molded into the tire is the maximum it can hold, not what your car wants.

Ford Fiesta ST tires: common questions

What size tires does a Ford Fiesta ST take?

The most common original size is 205/45R17. 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 Ford Fiesta ST?

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.
