S550 Mustang Wheel and Tire Fitment Guide - S550 Mustang Wheel and Tire Fitment Guide

The first year of the S550 Mustang began in 2015, which brought a ton of new features that steered the attention away from the classic Mustang looks. This was to make it look more modern while at the same time still creating the muscle car look that all know and love. Even though the S550 Mustang platform shared similar wheel specs as the S197 platform, it was introduced with an independent rear suspension. This was arguably the most notable change from the previous generations and has led to a variety of different wheel and tire offerings that we explore more of below.

This S550 Mustang wheel and tire fitment guide is for individuals wishing to upgrade their Mustang's wheels or tires between 2015 and 2021. This article will walk you through how to determine what sort of wheel, tire, and bolt pattern you have so you can locate the proper size and type for your car. Deep-dish wheels, backspacing, offset, tire fitment specifications, and numerous types of tires are all covered.


How To Measure Your S550 Wheels

If you're not sure what rim size you have, take into account the wheel diameter, wheel width, offset, backspacing, and bolt pattern while estimating their dimensions. Below, we go over each of these in greater depth:

Diameter

It's crucial to understand that while measuring the diameter of a wheel, you'll need to take two measurements: the Overall Wheel Diameter and the Actual Wheel Diameter. The entire diameter of the wheel is measured from the outer lip to the opposite outside lip. You'll need to measure the inside barrel of the wheel to the opposing inside barrel to get the actual diameter. If you have tires mounted on your wheels, this will be the third number in the tire's sidewall. For example, on a 245/45/17 tire, the 17 is the wheel's diameter in inches.

Width

When determining the width of your wheel, begin your measurement at the barrel section or real rim width rather than the whole outside rim width. If you have wide wheels and need to make further adjustments to your Mustang to make them fit properly, this is critical.

Offset

The offset of a wheel refers to the distance between the hub mounting surface and the centerline of the wheel. This is an important fact to keep in mind when shopping for your new set of Mustang wheels. The wheel's offset is measured in millimeters, and as a result, there are three different sorts of offsets. Positive, negative, and zero offsets are available.

A Positive offset means the hub mounting surface is facing the wheel's face.

The Negative offset is the polar opposite of a positive offset, in which the hub mounting surface faces backward on the wheel.

Finally, Zero offset occurs when the hub's mounting surface is parallel to the wheel centerline.

Backspacing

The distance between the mounting surface of the wheel and the center of the axle is known as wheel backspacing. When it comes to estimating how much room you have between your wheel and the fender, this measurement is crucial. Because too much or too little wheel well space might cause clearance issues, knowing your S550 Mustang's backspacing before making any adjustments is critical.

Bolt Pattern

It's critical to know what type of wheel you're looking for when determining the bolt pattern on your S550. Most S550 Mustang wheels have five lug nuts with a bolt pattern of 114.3mm, which is normally written like this: 5x114.3mm. Now that you've gathered all of the essential measurements, it's time to figure out what size wheel and tire you'll need!


How to Determine What Size S550 Mustang Wheels Your Car Requires

Depending on the year and model, Ford has used a number of offset and backspacing combinations for their longest-running pony car! We go through factory wheel diameters, bolt patterns, stud sizes, center bore, and offset for the S550 Mustang generation in particular. For the 2015-2021 Mustang EcoBoost, Mustang V6, Mustang GT or GT Premium, and Shelby GT500 vehicles, we list any additional wheel fitment specifications below:

  • Stock Wheel Size | 17"-20"
  • Stock Bolt Pattern | 5x114.3mm
  • Wheel Stud Size | 1/2"x14mm
  • Center Bore | 70.3mm
  • Offset | 35-50mm (H)

Should You Get Deep Dish Wheels If Your Offset Is Negative?

Deep-dish wheels are those with spokes that are significantly lower than the lip. The hub mounting surface is usually behind the wheel centerline, resulting in a negative offset. They're made to offer your S550 Mustang the most tire depth possible, giving it an aggressive, muscular look. LMR carries a variety of S550 Mustang Deep Dish Wheels to give you some variety in your negative offset appearance.


Why Is Having the Correct Tire Size For Your S550 Mustang Important?

What size tires should I obtain for my Mustang from 2015 to 2021? This is a frequently asked question, so to assist you in making this difficult decision, we've assembled all the information you'll need in one simple guide! One popular build customers enjoy is the staggered setup in which there are wider tires in the back compared to the front. We'll go through the suggested tire sizes for the front, drag front runners, and back below:

What Tire Type Should You Get For Your Ford Mustang?

Because tires are the only point of contact between your Mustang and the road, knowing what type of tires to use is critical. For this generation of S550 Mustangs, there are three tire options: Street Radials, Drag Radials, and Drag Slicks.

Street Radials

The most prevalent style of tire is the Street Radial. These are conventional street tires with enough tread to be used in a range of weather conditions on a regular basis. Because they have a stronger compound, these tires have the highest life expectancy.

Drag Radials

Another type of radial that is prominent in the racing sector is the Drag Radial. This radial tire has tread designed into the rubber, just like the street radial, but it is much smaller and has a much softer composition. The tire will still be DOT legal, but its lifespan will be significantly reduced. As a result, the soft compound won't need as much of a burnout at the drag strip to get them ready to race!

Drag Slicks

Drag Slicks are a type of Bias Ply tire that has several advantages for muscle car fans. When a car is launched at a drag strip, power is swiftly transferred from the drivetrain to the tires. A Bias Ply Drag slick's sidewall will flex or wrinkle to alleviate the shock of launching high-powered S550 Mustangs. This will protect car parts including rear ends, suspension setups (struts, camber, coilovers), and transmissions, among others. A bias-ply drag slick, on the other hand, will be a significant disadvantage if your vehicle will be conducting any high-speed cornering due to sidewall flex. Only straight-line racing should be done with this tire.
