Look at a car from the side, then from the front. The wheel face, tire shoulder and space beneath the arch all contribute to its stance. Fitment is the relationship between these parts. A useful starting point is a picture of the result you want, followed by a review of what your own vehicle can accommodate.
Continue with 20 vs 22 on large SUVs, how finish changes a build, or flush versus aggressive visual direction.
01 / Diameter sets the proportion.
A larger wheel face occupies more of the visible wheel-and-tire circle. When the overall tire diameter stays close to the approved original, the tire sidewall must become shorter. That changes the balance of metal and rubber beneath the arch. A smaller wheel with more sidewall reads differently, even when the car sits at the same height.
VISUAL COMPARISON / DIAMETER / SIDEWALL
CHANGE THE VISUAL BALANCE.
Hold the overall tire diameter constant.
The wheel diameter alone cannot tell you whether the complete setup fits. The tire size, rolling circumference, load requirements and space around the assembly need review. Michelin explains why plus sizing must account for the vehicle and tire together.
For your brief, share the current tire size and whether you prefer a stronger wheel presence or a fuller tire profile. Compare the vehicle proportions in our Range Rover design direction.
02 / Width changes the shoulders.
From a front or rear view, width changes how the wheel-and-tire assembly fills the car. The tire shoulder may look rounded, square or more exposed. That appearance depends on the particular tire as well as the rim. Adding wheel width also changes the space occupied on the inner and outer sides; offset determines how that space is positioned.
Use the tire manufacturer’s approved rim-width range for the exact tire. A wider rim is not permission to stretch an unsuitable tire. Continental requires approved tire-and-rim combinations and clearance under service conditions.
A useful reference includes a front or rear view, plus your current tire markings. Explore the contrasting wheel characters in the ARCRESO Collection.
03 / Offset moves the assembly.
Offset, often marked ET, is the distance between the rim centerline and the mounting face. Positive offset places that mounting face toward the outside of the wheel. With the same wheel width and vehicle hub position, reducing offset moves the wheel outward; increasing it moves the wheel inward. Change the width at the same time and both edges need a fresh comparison.
VISUAL COMPARISON / STANCE / POSITION
SAME WIDTH. A DIFFERENT POSITION.
Compare the tire edge with the outer arch.
Tucked: the outer tire edge sits further inside the arch in this illustration.
Tucked, flush and aggressive describe a visual relationship to the arch. They do not establish clearance or road legality. ENKEI illustrates offset and inner and outer clearance.
Send an arch-level photo and describe your preferred position. Start with the Fitment Guide offset diagram if the numbers are unfamiliar.
04 / Concavity gives the face depth.
Concavity describes the way the spokes descend toward the center of the wheel. Light and shadow make this depth especially visible from an angle. A deep face can give a build a sculptural character; a shallower face can feel cleaner and more restrained.
VISUAL COMPARISON / CONCAVITY / DEPTH
FORM GAINS ANOTHER DIMENSION.
Follow the spoke profile from the outer rim to the center.
Depth is a design preference, not a standalone fitment measurement. The actual wheel geometry, mounting arrangement and available brake and vehicle space need assessment. Vossen’s engineering overview shows how vehicle dimensions inform width, offset and concavity together.
Compare the ARC-01 Deep Concave study with the ARC-02 Split Spoke study. Tell us which face you prefer and whether the brakes are original or modified.
05 / Sidewall changes the balance.
The tire is a visible part of the design. A taller sidewall puts more rubber around the wheel; a shorter one makes the wheel face more dominant. Sidewall height follows both tire width and aspect ratio, so an aspect-ratio number on its own is not a height measurement.
Choose the tire for the vehicle and its use as well as its appearance. Confirm the exact size, load and speed requirements with a qualified tire specialist. The door placard and owner’s manual provide the original vehicle references; tires already on a used car may have been changed. Michelin explains how to read these references.
Describe the roads you drive and the tire look you prefer. Our Land Cruiser 300 direction begins with the whole vehicle.
06 / The arch completes the stance.
The final impression comes from the gap above the tire and the position of its shoulder beside the arch. Ride height, body shape and camera angle all influence that impression. A parked reference photograph captures one moment; it cannot show every position the tire takes while steering or the suspension moves.
Clearance checks must cover steering movement and suspension travel, including the tire’s movement under load. Continental’s plus-sizing bulletin sets out these checks. Mounting requires the correct interfaces and hardware as well as the desired stance.
Include your model year, suspension or brake changes, and current setup if known. The Patrol and G-Class pages show how a vehicle can frame the design discussion.
Build around your car.
Choose a visual direction, share your vehicle and show us a reference. Unknown specifications can stay unknown in the first brief. The review then separates your preferred look from the dimensions, responsibilities and feasibility that need confirmation.
