hodag, welcome. Stick around. Don't let the snippiness put you off.

Belting Tires - for every application!
Puncture protection from highly elastic specialty rubber is used between the tread and the carcass. Nearly impenetrable, this puncture protection fends off all types of foreign objects. Even a tack cannot get through. The carcass is effectively protected from damage. Tires with PlusBreaker can now be found in almost every segment: Be it racing bikes, Cyclocross or City/Trekking bikes, PlusBreaker guarantees maximum safety, without negatively impacting the riding properties of the tire.
The consistency of the breaker was adjusted so that the tires do not feel wobbly when taking curves. PlusBreaker is puncture protection through and through. Note: please check the recommended tire pressure weekly using a manometer. Plus tires are built very rigidly, making it hard to feel tire pressure. Tires used with too little tire pressure have higher rolling resistance and also wear faster.

and the breaker bead is on the outside of the casing, where it can protect it. And it can't interfere with mounting the tire, nor can it rub a hole in the inner tube. And it's thicker. Other than that, yes.

Yes, I did a face palm when I had to look it up.
On a related note, I pumped the tires up to 70, was at 65, seem to ride faster. Still heavy pigs but I guess I will keep them. Fixing flats on my way into work is tedious.

There are charts for air pressure for different weight riders/tires. These are good starting points, but it pays to play a little with the pressure (move it 10 PSI higher/lower and see how it rides)to see what works well for you.

Hmmm....
Charts you say?
I just went with what the sidewall said. The 5psi change to the 70max recommended did help. Comfort is not an issue, they're 35mm tires.

Just curious ... are there any hills where you ride? Although I would agree that rolling resistance is a big factor, tire weight is also important when going uphill. We have nothing but hills in western and central NC, and I have no doubt that heavier tires are slower and more difficult to ride uphill. I've got 5 road bikes with tires ranging from 23 - 35 mm (all folders), and the bikes with larger, heavier tires are simply slower going uphill. The larger tires roll nice on flat terrain but will give you a workout when you hit the hills.

There's a few "hills". I usually seek them out actually. But most of my commute is in a river valley so there are a few ups and downs no matter what. I went from a 35mm cross tire to these and the conti's are almost double the weight. Pumping them harder made a noticable difference. Googling now tryong to find the "Cyclocross Plus" tires in the above advertisement. No luck so far.

Hold the phone, Here is the original article of which the previously-linked chart is merely a summary. The original also contains a chart of minimum-inflation for mountain bikes.

When riding up a hill at a constant speed, additional weight of wheels is equivalent to additional weight anywhere on the bike/rider. So I'm not sure how to explain your experiences (except that on flat land, your biggest resistance is probably going to be air resistance and when your climbing hills, you're now in a regime where rolling resistance becomes more important).

When I was looking at tires (26 x 1.5), thought process went:
Panaracer T-Serv: light, but not the best puncture protection
Schwalbe Marathon: Heavy, but great puncture protection
The Panaracer RiBMo fell right in between the other two offerings, weight wise, and have proved more puncture protective than the T-Servs, but not at the weight penalty of the Marathons.

This is THE chart. However, I wish it went beyond 37mm. I've been thinking I could try to divine the formula (pressure as a function of width and load) that produced those lines, and generate a more comprehensive chart.

Thank you for that thread, RubeRad. I appreciate it.

Better? What are you using now? I like the panaracer pasela tourguard 70x35 on my crosscheck. 1 flat in four years. Your roads my vary.

Um... It's the total mass of the wheels, bike, and rider that matter. When accelerating, you count the mass of the tires twice, but this is still only a couple percent.
If it were the mass of the the that mattered, then it would be hard to get up to speed, but easier to maintain it, and yet we never hear anybody describe this benefit of heavy tires.
The composition of a tire makes a huge difference. Weight, not so much.

But it's the size of the effect that I'm pointing out. 200g difference over 50 kg total weight isn't a big effect. Rolling resistance changes from different types of tire matierials/pressures make a much bigger difference.
From an experimental point of view, these two properties (weight and rolling resistance) are hard to disentangle as heavier tires usually have higher rolling resistance.
The main point is that what a lot of people attribute to a "heavier tire" is really not because the tire is heavier, but rolls more poorly.

There are (what I consider) lots of hills where I ride.
