Wheel sizing

The millimetre is most commonly used to specify dimensions in modern production,[citation needed] but marketing of wheel sizes towards customers is still sometimes done with traditional systems.

A typical wheel size will be listed beginning with the diameter, then the width, and lastly the offset (+ or - for positive or negative).

Larger wheels are typically desired for their appearance but could also offer more space for brake components.

Running a wider tire allows for more of the vehicle's power to be put to the ground because there is a larger surface area making contact with the road.

The wheel has 5 lug nuts and utilizes a 100 mm bolt circle diameter.

[citation needed] Always check your owner's manual or call your local car dealership to confirm the bolt pattern on your vehicle.

Lug nuts (or bolts) will have either flat, tapered (conical), or ball (radius) seats.

The design of tuner lug nuts can range from bit style to multisided or spline drive, and are sometimes lightweight for performance purposes.

However, universal removal tools are available which grip the head of the locking nut using a hardened left-hand thread.

The success of locking wheel nuts depends on the determination of the would-be thief and the tools that they have available to them.

It is quantified by an ET value (from the German Einpresstiefe, literally press-in depth) and measured in mm.

A positive offset means the hub-mounting surface is closer to the outside edge of the wheel, while a negative offset means the hub-mounting surface is closer to the inside edge of the wheel.

Wheel width, offset, and its accompanying tire size all determine how a particular wheel/tire combination will fit on a given vehicle.

Offset also affects the scrub radius of the steering and it is advisable to stay within the limits allowed by the vehicle manufacturer.

Wheels that are not hubcentric are known as lugcentric, as the job of centering is done by the lug nuts assuming they are properly torqued down.

Plastic rings only provide initial centering, but are not strong enough to help support the wheel in case of high-speed pot hole hit.

This is followed by the aspect ratio (e.g.,"70"), which is the height of the sidewall expressed as a percentage of the nominal tire width.

The final number in the code (e.g.,"14") is the mating wheel diameter measured in inches.

[11] Such a wheel setup may be found on the Ford Mustang, Infiniti G35, certain models of Mercedes and BMW, etc.

Technically, wider wheels in the rear allow better grip with the road surface which is a performance benefit for better acceleration.
