I've been of the narrow high pressure tire persuasion, using Vredestein Fortezza Tricomp 23c at 140 lbs. This has worked very well for us riding our hometown, rather rural and low traffic roads. However, our tandeming world is expanding, as we've started leading group tandem rides near a neighboring metropolis. The roads there are much higher traffic and are littered with glass and other nasty objects. Perhaps the street sweeping budget isn't what it was. In any case, this past Sunday we had the Captain's Nightmare - our front tire sustained a serious puncture just before a righthander at the bottom of a fast descent.
Luckily I've been reading posts on this forum for a while, and practice my reaction series every time we ride: get on the other brake, assess oncoming traffic, assess traffic behind, and make a decision, assuming there's time for all that. We had no oncoming (yay!) and we went just a bit over the centerline before getting it back under control and stopping on our shoulder. Rim was OK.
We could try TG's suggestion and go to the plain Vredestein Fortezza, but my riding buddies vetoed. So I purchased a variety of single tires to test for rolling resistance and then ride. I only purchased tires with a good reputation for adhesion in the wet, good flat resistance, and yet some claim for low rolling resistance and good handling. I tested RR by putting the trial rear tire on my rollers and clamping the front end in a jig, then riding from the stoker position, so only the rear tire was rolling. I rode each tire at a 105 HR (no power meter) until I got a steady speed reading, 3-5 minutes. The differences in leg loading were obvious. I ran the series twice, testing each tire twice. Results, averaged:
Conti 4000, black chili-----25c-------120---------17.9
Vittoria Rubino Pro Tech--28c-------120---------16.8
Looks like the greater the putative flat resistance, the slower the tire, just what one would suspect. We now have the Conti 4000 on the back and the Durano on the front. We'll run each tire in turn on the back until it's worn out. We've already tried it with the 4000 on the back and a Vredestein on the front. Those different tires didn't seem to matter to handling. We'll see how it goes.
