Frequently Asked Questions

To ensure proper fitment, you need to verify:

• Bolt Pattern: Must match your vehicle's hub (e.g., 5x114.3, 5x120)
• Center Bore: Must match or be larger than your vehicle's hub diameter
• Wheel Size: Must have clearance for brakes, suspension, and fenders
• Offset: Must provide proper clearance without rubbing

Wheel offset is the distance from the wheel's mounting surface to its centerline, measured in millimeters.

Positive offset: Mounting surface is closer to the street side (wheel sits further in)
Negative offset: Mounting surface is closer to the brake side (wheel sits further out)
Zero offset: Mounting surface is at the centerline

Why it matters: Offset affects your vehicle's track width, suspension geometry, and tire clearance. The wrong offset can cause rubbing, poor handling, or premature suspension wear.

For 5-lug wheels (most common):

1. Measure from the center of one lug hole to the center of the hole directly across (skip one hole)
2. This gives you the diameter in millimeters (e.g., 114.3mm)
3. The pattern is written as: 5x114.3 (5 lugs x 114.3mm diameter)

For 4-lug wheels: Measure center-to-center of opposite holes (e.g., 4x100)

For 6-lug wheels: Measure center-to-center of opposite holes (e.g., 6x139.7)

Tip: Use a digital caliper for accuracy, or contact us with your year/make/model and we'll look it up for you.

Center bore is the diameter of the hole in the center of the wheel that fits over your vehicle's hub.

Proper fitment:

• Exact match: Wheel bore = Vehicle hub (perfect fit, no rings needed)
• Larger wheel bore: Wheel bore > Vehicle hub (use hubcentric rings)
• Smaller wheel bore: Wheel bore < Vehicle hub (WILL NOT FIT)

Why it matters: Ensures the wheel is perfectly centered on the hub, reducing vibration and preventing wheel wobble at high speeds.

Hubcentric rings are plastic or aluminum rings that fill the gap between your vehicle's hub and the wheel's center bore.

Do you need them?

• YES - If the wheel's center bore is larger than your vehicle's hub diameter
• NO - If the wheel's center bore exactly matches your hub diameter

Why they matter: Hubcentric rings ensure the wheel is perfectly centered on the hub, reducing vibration and preventing wheel wobble at high speeds.

Wheel sizing is written as Diameter x Width (both in inches):

• First number (18): Diameter - height of the wheel from edge to edge
• Second number (9.5): Width - measured from inner bead seat to outer bead seat

Larger diameter = lower profile tires (better handling, harsher ride)
Wider wheels = wider tires (better grip, more aggressive stance)

Cast Wheels:

• More affordable
• Great for street use
• Wide variety of styles
• Heavier than forged

Forged Wheels:

• Lighter and stronger
• Better performance
• More durable
• Higher price point

Flow-Formed Wheels:

• Middle ground between cast and forged
• Lighter than cast, more affordable than forged
• Great for performance builds on a budget

Common wheel finishes:

• Powder Coated: Most durable, chip-resistant, various colors available
• Painted: Wide color range, less durable than powder coat
• Chrome: Mirror finish, requires more maintenance, can peel if damaged
• Machined Face: CNC-cut aluminum finish, modern look, needs clear coat protection
• Polished: Shiny aluminum, high maintenance, shows scratches easily
• Gloss Black: Popular, hides brake dust well
• Matte/Satin: Modern flat finish, moderate maintenance
• Bronze/Gold: Trendy finish, pairs well with certain car colors

Durability ranking: Powder Coat > Painted > Machined > Chrome > Polished

Load rating is the maximum weight a wheel can safely support, measured in pounds or kilograms per wheel.

Why it matters:

• Wheels must support your vehicle's weight plus cargo/passengers
• Underrated wheels can crack, bend, or fail
• Especially critical for trucks, SUVs, and performance cars

Finding your required load rating:

1. Check your vehicle's gross vehicle weight (GVWR) in the owner's manual
2. Divide by 4 (or number of wheels)
3. Add 20-30% safety margin
4. Ensure wheels meet or exceed this number

Pro tip: Our team verifies load ratings for your vehicle. Contact us if you're unsure!

It depends on the lug nut seat type:

• Conical/Tapered Seat (60 degrees): Most common, cone-shaped
• Ball/Radius Seat: Rounded, often used on aftermarket wheels
• Flat/Washer Seat: Flat with a washer, common on trucks
• Mag Seat: Flat seat specifically for mag-style wheels

Important: Using the wrong lug nut seat type can damage your wheels or cause them to loosen while driving.

Pro tip: Most aftermarket wheels require conical seat lug nuts. If your stock wheels use ball seat lugs, you'll need new ones.

It depends on your situation:

• Transferring from old wheels: Your existing TPMS sensors can usually be transferred to your new wheels during installation
• Buying a second set: If you're keeping your stock wheels (e.g., for winter tires), you'll need a new set of TPMS sensors
• Broken or old sensors: This is a good time to replace failing TPMS sensors

Pro tip: Most vehicles manufactured after 2008 require TPMS by law. Your TPMS light will illuminate if sensors aren't installed or functioning.
