Aftermarket alloy wheels are a modification to the vehicle's standard specification and can affect value, theft risk and repair cost. They are therefore relevant where the insurer asks about modifications.

How insurers commonly treat this

• Factory-option wheels can be treated differently from wheels fitted after manufacture.
• Wheel size, value and other suspension or body changes can also be relevant.
• The quotation can change once the modification is declared.

What the quotation may ask for

Quotation forms use the information supplied to determine which insurers can offer cover and on what terms. Where the available answer does not accurately describe the circumstances, the insurer or comparison provider can clarify how that information is recorded.
