28mm Tires for Touring: Belted or Beltless?

I'm mechanically limited to the size of tire, because of my Serotta F3 forks. I'm doing research to see if I can fit a 700C tire with an actual width of around 28mm. The wheel rims are DT Swiss, model RR1.1, with 28/28 spokes.

I'm wanting to experiment with credit card tours. The rider weight is 160 lbs, the bike weight is 20 lbs, and I would probably not carry more than 15 lbs.

The touring would be in Southeast Michigan. My question: what is the consensus of using belted versus beltless tires on a credit card tour?

For argument, I also ask: What would make a better touring tire, for the above weights on a credit card tour: The 28mm beltless Rolly Poly ... or ... the 28mm belted Ruffy Tuffy?

Call Serotta and make sure it will fit.

The Rivendell tires are 27c. I used the Ruffy Tuffy for years. It's a nice tire and I have done several tours on it. That's the way I'd go and the way I went.

I don't know about the Roly-Poly or the Ruffy Tuffy, but I too, have some size constrictions (fenders) and went with Conti Ultra Gatorbacks, 28mm's. They're mounted on Velocity AeroHeads w/32 DT DB spokes. I took my first semi-loaded spin on them yesterday. Had about 20 - 25 lbs. in rear panniers (went grocery shopping, first). I was very happily impressed. Once I got up to speed it was hard to tell that I was carrying anything at all, except for a bit of lightness in the front end on upgrades, which wasn't a problem, just something I noticed. They seemed to roll as fast and easily as 23's or 25's (no tread on the G-backs) and they delivered a very smooth, cushy ride as compared to the narrower, higher pressure tires. Not that the G-backs are much wider than those mentioned above—they're not—they're fractionally wider at best. But, they are taller and I believe that accounts for the posh ride. Just throwing them out there as a tire to consider.

I've used the Conti Gatorskins 28's like Foamy above. Very similar in size to many others 25's. Work well, just make sure you keep the presure up in the rear tire to avoid the snake bites, not that I would know anything about this error in judgement

I'm another Gatorskin user who's pretty satisfied. The bike is a 2005 Specialized Roubaix Elite and I've fitted 28x622 tires. With 90 psi iniflation pressure the ride is plush and there's about 1/4" clearance on both sides and at the top of each tire.

Regards,
Bob P.

Thanks everyone. I checked the Serotta site, and got some good nuggets of information. Following are cut'n'pastes from their forums:
START
03-28-2006:
* Continental 28c Gatorskins are not as wide as Michelin 25c Pro Race Lites.
* Conti 28c 2000 (kevlar folders, my favorite cheap "race" tire) are wider than Gatorskins, not as wide as Michelin 25s.
* Rivendell 27c RolyPolys are wider than both the Contis and Michelins.
* Conti 25c GP3000s are 23s. 23s are really skinny. My Pegorettis currently in stable will not allow more than a Conti 25c in the rear for the brake bridge clearance.
* Avocet 28c FastGrip DuraK are true 28s, wider than the Rivs, perhaps the perfect size for me. Will not fit under the Reynolds Ouzo Pro fork.
* All the other tires I have marked 25c are nowhere near 25c. The Michelin Pro Race 25c has got to be the lightest, most appealing clincher out there and appears to fit under every modern carbon fork I have (too many to list). The problem arises in the rear either with the brake bridge or the seat tube (frt der. clamp).


FYI the F3 fork will handle a Rolly Poly with ease as stated by a fellow forumite that has mounted these tires on said fork. This in response to a query of mine on this subject.

Question: I just ordered some Mich Pro Race in 25c. Do I need to be concerned about using a a tube that is marked for 18-25c?
Answer: I use 18-25 tubes in everything up to about 27. Only in the 32s I sometimes stick on the cross bike do I go with anything bigger. Although if they're the superlight 18-25s, you may need to top them off pretty frequently.

I'd just add that even Michelin 23s are wider than most 25s and, while perhaps a bit too skinny for Douglas's taste, are a good clincher option for those who have been riding other 23s and find them too hard/skinny but don't want to go the TWO steps up in size to a Michelin 25. I'd also add that while Michelin 25s are skinnier than Roly Poly / Ruffy Tuffys, it aren't by much. Perhaps a whisker, perhaps two. And they feel a good bit lighter and snappier to me, although they're not near as tough.

10-03-2007:
My Ottrott ST with F3 fork and 41.5cm chainstays and Shimano 9 speed D/A brakes takes Panaracer Pasela TG 28c's with ease. More than wide enough as it is not a touring bike.

The Pro2Race 25 is really close to 27mm wide.

03-16-2008:
It might depend upon the length of your chainstays...but I once put 28c Pasela TG's on my Ottrott ST with 41.5cm chainstays to ride a packed dirt trail. My Ottrott ST has the F3 fork.
STOP

I currently have Pro2 Race 25mm tires on DT Swiss RR1.1 rims, 28/28 spokes. A gentleman on the Serotta website cautioned about using too wide a tire on the DT RR1.1 rims, as I was discussing the possibility of using 32mm tires. Here are some conclusions I've made from visiting Serotta's website:
* My Legend ST is a race-bike, not a tour bike. But then, that is what I got it for, to keep up during club rides.
* It would not be wise to use wider than 28mm tires ... because:
a. The available rear tire space inside the seat stay would probably not accept more than 28mm.
b. The F3 fork would be hard pressed for wider than 28mm.
c. I should not press my luck with higher than 28mm tires on the DT Swiss RR1.1 rims.
* Start saving my money ... and start looking for a tour bike to get.

BUT, for now, I do want to practice doing longer rides on the Legend with 28mm tires. I've narrowed my tire choices for the Legend, and want to try both the Michelin Pro2 Race 25mm ... and the Panaracer Ruffy Tuffy 28mm.

One question I have though, is that with my assuming the Ruffy Tuffy sounds to be geared for touring ... and the Pro2 Race sounds to be geared for racing ... why then are the recommended tire pressures lower for the racing tire?
* Panaracer Rolly Poly 28mm: 90-120 PSI.
* Michelin Pro2 Race 25mm: 73-102 PSI.
