What size are Ford Fiesta wheel nuts?

If you own a Ford Fiesta, knowing the proper wheel nut size and torque specifications is important for changing a flat tire or replacing your wheels. The wheel nuts help secure the wheels to the vehicle’s hub assembly. Using the right socket size and tightening the lug nuts properly ensures your wheels are safely attached. In this article, we’ll look at the recommended wheel nut size and torque specs for different Ford Fiesta models.

What size socket are Ford Fiesta wheel nuts?

Most Ford Fiesta wheel nuts are M12 x 1.5 thread size. The wheel nut socket size can vary depending on the model year and trim level of your Fiesta. Here are the most common lug nut sizes:

  • 19mm– This is the most common lug nut size on many Fiesta models encompassing 1990-2023 Fiesta, 2018-2022 Fiesta Active, Fiesta Classic and Fiesta Ikon. A 19mm six-sided socket (also called triple square) is needed to remove the wheel nuts.
  • 14mm– Some older Fiesta models from 76-89 use a 14mm hex socket lug nut. Check your owner’s manual or the nut itself to verify the size.

Always double check the socket size before attempting to loosen the nuts. An improperly sized socket can round off the nut making it very difficult to remove. The correct socket should fit snugly over the nut without wobbling.

What torque spec are Ford Fiesta wheel nuts?

Along with the proper socket size, you’ll need a torque wrench to tighten the Fiesta’s wheel nuts to the factory specification. This ensures the wheels are securely fastened without over or under tightening. The recommended torque is:

  • 80 ft-lbs (108 Nm)– The torque spec for 14mm Fiesta wheel nuts is 80 ft-lbs.
  • 89 ft-lbs (120 Nm)– The 19mm wheel nuts on the Fiesta require 89 ft-lbs of torque.

Always torque the lug nuts in the star pattern sequence indicated in your owner’s manual. Tighten the nuts in increments up to the final spec. Do not lubricate the threads unless specifically directed to do so.

Following the proper wheel nut tightening procedure keeps your Fiesta’s wheels firmly attached while preventing damage to the threads.
