What is the fitting of the wheels?
Wheel fitment is a term used to describe how the wheels fit into a wheel well or beneath a vehicle’s wheels. Wheel and tire packages are critical to how your car performs and looks.
In other words, the grip between the car and the road is most likely the intended meaning of this fitting. Therefore, lowering your vehicle naturally impacts the chassis, camber, rims, and towing tires.
A system of bolts
The bolt pattern describes the number and diameter of lugs (and lug holes) on a wheel. 5.5 inches, or 4100 millimeters, is the term used to represent a bolt pattern.
Diameter is Important
All that matters is that you choose tires that have reduced aspect ratios so that you end up with an identical overall height. The diameter of the wheel was extended without affecting the circumference or outside circumference of the tire, allowing you to maintain essential elements like your speedometer and traction control systems in place.
But, Widths Matter More
Wheels with wider rims help improve the vehicle’s overall stability, handling, and steering feel. Offset is the first thing you need to grasp before going on and adding any additional width to your vehicle.
The distance between the wheel’s centerline and its hub-mounting surface determines the offset. Lateral wheel positioning, track width, and suspension response are all influenced by this.
Offset
Offset refers to the distance between the mounting surface of a wheel’s hub and its centerline. Offset might be zero, positive, negative, or none of the above.
Positive offset
Wheels with a positive offset are mounted toward the front of the wheel or to the wheel’s side.
Negative offset
A negative offset occurs when the mounting surface of the wheel hub gets placed more to the rear of the wheel’s centerline than the positive offset does.
Zero offset
When zero offsets become applied to a vehicle wheel, the hub mounting surface is parallel to the centerline of the vehicle wheel.
Grip, handling, and stability at the wheel will improve if you get it correctly. An excessive negative offset can cause hub bearings to wear out, resulting in rubbing and noise.
Knowing the offset of your original wheels is the first step in doing the job correctly. Eddie Lee, a Mackin Industries employee, explains how to measure accurately.
Have the Right Amount of Knowledge
Measure the wheel’s width, or check for a set of numerals on the wheel’s backside. You may find the wheel’s centerline by dividing its width in half. A negative offset is simply a backspacing that is less than the centerline.
Ensure that the distance between the tire and anything it could hit, such as a suspension part, is measured. In the absence of additional room, you may want to explore reducing your wheel’s offset to push it away from the suspension. Because no two tires are exactly alike, you should factor in an extra 1/8 inch when making your estimates.
Lug nuts and wheel studs vs. bolts
They can be flat, conical, or ball (radius) seats for lug nuts (or bolts). The flat end of a flat seat presses the wheel against the mounting hub, causing it to become compressed.
There is a conical or semicircular end to tapered and ball seat designs. If you have aftermarket wheels, you can get the lug nut type by looking at the OEM (Original Equipment Manufacturer) specs or contacting the wheel manufacturer directly.
Aftermarket wheels may have lug holes that are too small for regular lug nuts, so you’ll need a socket to tighten them down. They developed tuner lug nuts to remedy this problem by including a unique key that allows removal and installation using a regular lug wrench or socket known as the Tuner key.
The “locking wheel nut” is another lug nut variety used to prevent the theft of a vehicle’s wheels. To fit and remove this particular nut, you’ll need a unique key (usually a computer-designed, round star form).
Basic Fitment for Ford Focus ST/RS
Ford Focus ST/RS 18-Inch Wheels
It’s common to see 18×8.5 wheels with a +35mm offset and 235/40 or 235/45 tires mounted on them. No fender alterations were required, which was essential for the owner. Overall, this is a decent configuration that does not necessitate any adjustments to the wheel well or rubbing.
If you’re a fan of stretchy boi, most Focus ST/RS models run 18-inch wheels instead of the stock 18×8.5. For those who prefer the look of a larger tire, a 245/40 might be a good choice. There is a bit less room in your rims, but most people using this setup don’t have a problem with their tires rubbing.

Ford Focus ST/RS 19-Inch Wheels
19×8.5 +42mm is the most frequent offset for a 19-inch rim, but offsets can range from +35mm to +45mm. Offering a virtually flush fit with these precise wheel specifications, which most customers are seeking. No trimming is required unless the wheel diameter is so small that there’s no need to be corrected.
When it comes to air suspension with 19-inch wheels, most people use the same 19×8.5 wheel size with offers ranging from +35mm to +45mm, which is the most common configuration. It’s important to remember that as you air out your tires, you’ll need a little more tucked-in fitting.

Is it Expensive?
The cost of mounting and balancing tires varies widely based on the size, location, and tire installation facility you pick, but it may vary from $15 to $45 for each tire.
