74.1 mm center bore: if your vehicle's hub is smaller, a centering ring fills the gap and ensures the wheel is properly centered. Rings are supplied according to the vehicle you specify.

TÜV approval: this model is certified by the German organization, the most demanding reference on the European market. The report lists the covered vehicles and, where applicable, the mounting conditions. Ask us for the report corresponding to your vehicle if you need it.

Machined to order

Specify your vehicle when ordering

This Concaver is not pre-machined: its bolt pattern (5 holes, from 108 to 130 mm) and its offset (ET 10 to 46) are machined to your specifications. Enter your exact vehicle model in the form above — without this information, the wheel cannot be manufactured. Not sure? Contact us before ordering; we will determine the correct specifications together.

Custom offset: the wheel is supplied in ET 10 by default. If you want another value within the range, specify it in the form: machining to this specification costs €20 per wheel, automatically added to the cart.

You place your order

Choose the diameter, width and color, then enter your vehicle and, if needed, the desired offset (+€20 per wheel).

We confirm the specifications

We check the bolt pattern, offset and clearance on your vehicle before starting production.

The wheel is machined

Allow approximately one additional week for machining or a custom paint finish.

Shipping

Delivered with the appropriate hardware, centering rings and center cap.

What's included

Concaver CVR1 21×10.5" wheel (sold individually)
Hardware adapted to your vehicle — included
Centering rings adapted to your vehicle — free with any order of 4 wheels
Matching Concaver center cap — always included, regardless of quantity
TÜV approval
Bolt pattern and offset machined to your specifications
Maximum permissible load: 980 kg per wheel

Construction: hybrid forged

Concaver uses Flow Forming, also known as flow forging: the wheel is stretched while hot as it rotates, densifying the material around the tire bead. The result sits between a conventional cast wheel and a fully forged wheel — significantly stiffer and lighter than the former, without reaching the cost of the latter.

This process allows Concaver to offer deeply concave designs in large diameters at an affordable price.

Why Concaver

Machined to your specifications

Custom bolt pattern and offset: the wheel adapts to your vehicle, not the other way around.

TÜV-approved

The most demanding European certification, rare in this price segment.

Pre-purchase advice

Bolt pattern, offset, clearance, camber: we confirm the fitment with you before machining begins.

Mounting and hardware

Unlike most brands, the appropriate hardware is included with your Concaver wheels, along with the centering rings and center cap. Simply specify your vehicle when ordering.
