Measure how thick the tire is through the lug and buy sheet metal screws about 5mm longer than that, and corresponding nuts for the screws. Drill out the center of the lug, thread a screw through the hole and lock it in place with the nut.
Sheet metal screws have domed heads and are less likely to do damage, even if you don't use a tire liner or other protective strip.
