First dibs on that perfectly good tire he's going to throw away, now that you guys made him all nervous...
I'll throw context in here. He;s not headed off around the world via Outer Mongolia he takes leisurely rides within an hour or two tops of metro Phoenix. Odds are that tires going to age out well before it wears out. It'll be fine.Like I mentioned an ordinary tube patch applied inside the tire mostly so no sharp edge from the hole has a chance to wear on the tube it'll also prevent any chance of moisture or dirt getting INSIDE between tire and tube, and off he goes.
But I used to be a rural mailman and it wasn't unusual to be riding around on a car tire with 3 or 4 plugs in it, usually repaired on the side of the road without even taking the rim off the car. On a good day I could do it and have enough air left in the tire to drive to a gas station before adding air. Driving with the window down a telltale clicking was a giveaway I picked up another nail or screw.
In Wyoming on the Royal Star (tubeless tires) I picked up a nail? in the rear, drove 60 miles to the next exit before pulling off cuz handling had slowly and steadily deteriorated, was doing 80 ended up down to 60 on a deserted freeway. By time I was in the gas station parking lot the bike was down on the rim. AHA that's why handling got so bad, LOL. Drove across the road to a gas station with an air pump worked the bike up on some 2x4s, no center stand, found the hole (nail was gone). I carried a patch kit so put in a gooey plug. Pulled valve stem, got lucky and got the bead to reseal. I never even removed the wheel from the bike, and continued back to wisconsin at 75MPH. Ran that tire til it was out of tread several thousand miles later.
