The OE tire sizes for the Honda GB350S (2021–present) are 100/90-19 front / 150/70R17 rear. Below are tires in these sizes, compared across brands. OE rim widths for this bike are not on file, so no rim-width badges appear. OE sizes can differ by model year and market — the sidewall of your own bike is the sure reference.

- 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.
