I carry a tire plug kit in my van. Low pressure light came on and quickly made my way to air pump. Checked out tire and was at least a 5/16" bolt right between tread, very easy to locate (hissing). Inflated tire, prepared plug, pulled out bolt, inserted plug done. Almost home light came on again. Used water soap and plug was still leaking. Tried double plug and still leaking, but would take days to trigger low pressure light. Tire still had decent tread and didn't have facilities to patch, so got a can of fix a flat. I have never believed in this stuff, but it worked. No low pressure warnings for about a month. Around here they would charge $50 for a patch, 2 .25 cent soft rubber plugs and fix a flat, problem resolved!
