How to read this

• The 1–5 ratings are our own estimates. Not manufacturer figures, not measurements.
• Within one model, character and street legality both change with the size and the spec. Confirm with the manufacturer or a dealer before you buy.
• Shop links go to search results rather than product pages. Other sizes and older models will be mixed in.
• “Narrower” means one or two steps below the OE size. The “rim width OK” badge means the tire maker's published rim widths line up with the OE rim width; no badge means unconfirmed.
• Competition tires may not be used on public roads.
