GSX-8R tires

The OE tire sizes for the Suzuki GSX-8R (current as of Aug 2026) are 120/70ZR17 front / 180/55ZR17 rear. Below are tires in these sizes, compared across brands. OE rim widths are F3.50 / R5.50 (from official specs; used for the rim-width check). OE sizes can differ by model year and market — the sidewall of your own bike is the sure reference. This is a Japanese-market lineup; the sizes themselves are international.

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.
