Wheel/Rim Size Calculator shows the acceptable wheel/rim width range for any given tyre size in accordance with the ETRTO standards and Databooks of the leading tyre manufacturers. It gives You the answer to the question "What rims fit my car?"

Each tyre manufacturer has a specific rim width range on which the tyre can be mounted. Failure to follow rim width recommendations may result in poor tyre performance or possible wheel and/or tyre failure.

Choosing a wheel near the middle of the accetpable wheel range will give a balance between ride quality and handling. A wider wheel will improve handling at the expense of ride quality, while a narrower wheel will improve ride quality at the expense of handling. Consider these compromises when selecting wheels.

Into the form below, select the tyre size and click on the button "Find Rim Size". The table containing the recommended wheel/rim sizes for the selected tyre dimension will be presented below the calculator.
