Tires that cover front and rear (3 models)

Front + rear set: 3 models can cover both ends (matching sizes in bold, based on F=60/100-12 / R=70/100-10). 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.
