I'll add my $0.02 and recommend the Panaracer Col de la Vie. I put a set on my '72 Raleigh Sports and they look and ride wonderfully. I have a set of Schwalbe Marathons on my Raleigh DL-1 and they also ride very nicely, so the Schwalbes are also a nice option. My Raleigh Trent Sports came with the 32-597 wheels and tires which are now a very odd size to find so I had a set of 700C Sun CR18's build up with an old Raleigh front hub and a S/A FW rear gear hub then installed Panaracer Pasaella Tour Guard tires. With new brake pads, the bike rides and stops suprisingly well for a 50 year old bike. PG.
