Experience says that tubeless tires/rims are really the only way to go as they can be plugged from outside (usually) without needing to remove the wheel from the bike, remove the tire from the wheel, re-seat the tire on the wheel, etc etc etc. Just carry a plug kit, some compressed air (or small air compressor), and some tire foam "just in case" to reinflate a partially deflated tire. Also a spare valve stem and stem tool can be helpful (those little valve stem cores can go bad)
When possible, remove a punctured / plugged tire and install a proper internral patch (not plug) from the inside out. That eliminates the chance that the plug could pull out or be pushed in causing deflation...
Lots of guys are running "slime" in their tires too, which helps reduce punctures where the nail goes in and comes back out. I pick up a few bottles from USA every time i travel back n forth.
How many plugs? 0 to be safe but if the puncture holes have been very small, like what would be caused by a small screw or nail, or a hole not wider than 2 to 3 mm, or odd-shaped, then the plugs that I've used have stayed put beyond the useful life of the tire tread.
Those fancy laced (spoked) wheels may look good, with the glittering chrome, but they are not worth a darn if sitting on the side of the road. The fix-a-flat foam does *not* work in tube tires, and typically the tube rips a bit after it gets popped meaning often it can not be salvaged / reused / patched properly. Also, deflation is rapid with a tube tire leading to possible blow out / loss of control. Most of the time, a flat on a tube means the end of riding for the day, loading the bike on a truck to get it to the nearest service station, or as a minimum several hours in the sun, jacking the bike up on rocks, removing the tire, sweating your @55 off trying to break the bead, remove the inner tube, putting in the new tube and hoping it is not pinched, then pumping the hand pump like mad trying to re-inflate and re-seat the bead.
My tire tool kit contains: plugs, plug inserter tool, extra valve core, extra valve stem, and either 4 bottles of CO2 compressed air with inflator tool, or now they also sell these very small air compressors (pocket size) that run on 12V. Hooking it to the battery and running the bike while inflating the tire works good. And can be done multiple times (where as
CO2 Kits & Accessories cartridges are good for 1 inflation but if you have a slow leak, you could get stuck again). Tire irons are helpful but extra weight....and then toss in a a spare tube (for your buddy who just wont trade his fancy harley spoke wheels for tubeless wheels) ...
Always buy good tires. Your life could depend on your tires and brake pads...
