In an ideal world, people would walk their soles through evenly, right in the centre of the sole. But people walk differently and according to their individual walking pattern, put different stress at different sections of the soles. Some people have no problems with excessive wear of the tips, others do, particular if the shoes are pointed and elongated. I ruin my toes in next to no time and, even as a child, had metal toe pieces nailed on. About six or seven years ago, I discovered toe pieces that were actually set into the sole. I believe that is the best way to protect the tips if you wear the toes hard. J M Weston and the German firm of Dinkelacker produce some of their heavier designs with these set-in toe pieces as part of the specifications. Otherwise you'll have to find a cobbler who can fit them. It's quite a delicate job and very few still can do it.
Second best solution are nailed on toe protectors in either metal or plastic. Third is an additional row of nails in the toe area. (I ruin these almost as fast as if they were not there.) But you might not be as hard on your toes as I am. Toe pieces (even metal ones) don't make any excessive noise; metal heals make one hell of a noise. (I once tried them and had them removed a week or so later.) Ultimately it all depends on your particular walking pattern.
