Tire choices for my new Fulcrum 5's?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them.

Tire choices for my new Fulcrum 5's?

I'm currently using stock Mavic CXP-22 wheels with 25c Specialized All-Condition tires. These both came with my Allez. I have a new set of Fulcrum 5's coming on Monday and am not sure what to do in terms of tires for the new wheels. I've read the recent threads on here about Wheel Energy and their findings in terms of wider tires achieving lower rolling resistance and am still confused about what to do.

The ride has been comfortable on my current setup (running around 95psi) but yesterday I rode with a buddy and tried his backup wheels (old but still super-smooth Dura-Ace wheels with 23c Conti tires) and noticed quite a few differences. I'm not sure how many of those differences were because of the wheels or the tires. I put the 25c tires on mine originally because I'm currently at 6'2" and 190lbs (yes, even though I'm in gym shape I know I'm too fat for this sport and could drop a few pounds even though I don't look like I need to) and wanted something a bit more comfortable. Usage is 2 short rides (~20mi) after work during the week and a longer weekend ride (45-55mi) either on a fast (for me) club ride/by myself/with friends who are faster than me. I've also got a calendar of some event rides coming up (Palm Springs this next weekend, etc).

Should I just put the same tires on the new Fulcrum wheelset? Would that be stupid because the new wheels will be lighter/stiffer and would also benefit from a nice set of 23c tires? In my situation, what factors (tire width, pressure, rolling resistance, etc) will make the biggest difference in terms of performance? I certainly don't want to be super uncomfortable, but I will happily tolerate some more discomfort if it will yield a significant performance improvement.

Thanks!

Thanks. In 23c or 25c? That's my primary confusion. Those Vittorias look nice, though.

25c and lower the pressure.

I've read several threads recommending Vittoria's with this wheelset because they supposedly fit these very slightly oversized rims better. I also have a set of Fulcrum 5's on the way and I think I am going to just bring them to the LBS and see what they have that will fit well.

I know it will be a bit more expensive but I want them to put on a cassette that I'm getting off of Ebay so I figured if I buy something, they'll probably do it for free and I don't have to buy a tool I'll probably lose before I need it a 2nd time.

Good thinking. I should probably do the same. Did you get the Fulcrum's when Bonktown had them? Screamin' deal on those wheels.

That's what I'm doing now. So you'd recommend the same thing, then, just with better tires than the Specialized ones I have?

Depends. Are you keeping the Mavics? If so, then just get another pair of tires.

If you're getting rid of the Mavics and keeping the tires, just use those tires until they die.

Yep. Some sharp looking Eastons went on sale shortly after that I probably would have bought had I not already ordered the Fulcrums.

Yes, as a backup set. I'm not buying a new cassette just yet, so I guess I could just swap the tires. I plan to get the new cassette before too long. So the potential performance gain from narrower tires at higher pressures doesn't seem worth it for what I'm doing?

I almost bought those too (the Circuits, right?)-- except I found out that if you have anyone but Easton true/work on the wheels, you void the warranty. I understand why they do that, but the convenience of being able to have my LBS work on my wheels if I need them to pushed me toward the Fulcrums.

I don't think so.
