MEGURO K3 tires
The OE tire sizes for the Kawasaki MEGURO K3 (2026 model) are 100/90-19 front / 130/80-18 rear. Below are tires in these sizes, compared across brands. OE rim widths are F2.50 / R3.00 (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.

Bridgestone aims it at “on-road-centred adventure touring.” Strong on 19-inch fronts — 110/80R19, 120/70R19, 100/90-19 — so it fits the front of the CL250, CL500 and 400X. Rears go up to 150/70R17 (CL family) and 160/60ZR17 (400X).

Avon calls it “the ultimate custom tyre,” for large cruisers and tourers. AV91 front and AV92 rear are separate part numbers. Its real distinction is the ultra-wide sizes — 240/50R16, 330/30R17, 300/35VR18 — which make it one of very few tires that fit the Rocket 3’s rear. Availability in Japan needs checking.

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.
