Tires that cover front and rear (7 models)
Front + rear set: 7 models can cover both ends (matching sizes in bold, based on F=70/100-19 / R=90/100-16). Shop links search on the model name alone. “Narrower” means one or two steps below the OE size. “Rim width OK” means the tire maker’s published rim widths line up with the OE rim width. No badge means we could not confirm it; combinations we found to be wrong are left out entirely.

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.
