I've booted tires with a larger tube patch, especially those patches that are reinforced. But, I've also seen tires that are nicked in the tread area that have damage to the belting. Those will generally last a short time before breaking more belting, making the tire unsafe. I'd keep it on the rear, and be ready to go crazy with the "thump, thump, thump" it'll make.......nah, I'd just buy a new one.
