What are the smallest/skinniest sized tires you guys/gals ride on?

I'm a clyde, 5'11" 275 lbs (down from 367) and I'm buying a 2009 Spesh Tricross Comp. It comes with 700 32c tires and 24 spokes (roval). When I test rode it, the tires seemed fine. I was wondering, should I get a wheelset that has more spokes? Are there any Clyde's or Athena's riding 25c or even 23c tires?

Sure, I used to ride on 23mm tires but now I stick with 25mm. I don't know if my bike has room for 28 or I'd probably do that.

You have a cross bike - one advantage is the ability to take on rougher, more varied terrain. You'll be giving that up with skinnier tires. If at some point you want to fiddle with skinnier tires, by all means try 28mm.

I ride 700x25 because that's the biggest tire I can squeeze into my CAAD9-4 frame; I think... maybe I should attempt a set of 700x28s; if they won't fit, my daughter has a Synapse and I know it can take 28s. I rode on the stock 23s for a while, but noticed an appreciable ride quality difference by going to 25s.

If the tires seemed fine, why would you want something else? I use 25mm tires on my road bike, but only because it can't fit anything wider. On my touring bike, I use 32mm or 35mm Vittoria Voyager Hyper tires. The Hyper is light-weight (for it's size) and fast! If you need more flat protection, try the Vittoria Randonneur Pro. They're just a bit heavier than the Hyper's but have a bit more puncture resistance in my experience. If you have to have a small tire for some reason, make sure they'll fit on your rim before buying. 25mm tires are the smallest that can possibly fit on my touring bike's wheels. Not sure I'd want to run anything smaller than 28mm, though.

If I were you, I wouldn't buy new wheels unless you start to have problems with your current wheelset. If you're worried about the wheels, have an expert wheel builder check the spoke tension and wheel trueness.

I think I'll have the lbs make sure the spokes are proper.

IMHO there is absolutely no advantage to going to 23mm tires. Research over the past several years has shown that rolling resistance is actually lower on slightly bigger tires and the weight penalty is minimal. Even among the pros, you aren't seeing very narrow tires. For a Clyde of your size, I recommend a good quality, supple 25mm tire as your minimum width. If your bike has the clearance, a 28mm might even be better. In addition to the objective factors like rolling resistance, weight and aerodynamics, there are also subjective factors such as increased comfort and confidence on less than ideal road surfaces. I found 23mm tires (Conti Ultra Sport II) to be rather squirrely on sandy corners, wet surfaces or where there were a lot of cracks running lengthwise in the road. 25s and 28s feel much more sure-footed to me and take a lot of the road vibration out of the ride. I would much rather blast through rough sections or bomb down hills on my slightly wider tires and my overall times with mid-width vs. narrow tires are pretty much identical.

I never had any intention on going with smaller 25c tires. I was just thinking forward on possible future upgrades. Thanks for your reply :thumbsup:

I ride 700x28c, and see absolutely no reason to go any skinnier. I ride super-duty (read: super heavy) Thickslick Elites because I ride on seriously crappy roads, occasionally in seriously crappy parts of town, so I need a tire that trades durability for well, pretty much everything else. I'm not kidding-- I want to emphasize-- I will voluntarily ride through areas that make friends and family say, "Are you sure that's a good idea?" so I have no intention of having to stop to fix a flat. Also, a tire with this low of a thread count (27tpi) would just be physical savagery in a 25 or god forbid a 23. So while your needs are probably different from mine, there is one nugget you can take away-- in a wider tire, you can get away with lower thread counts without significant loss of ride comfort, meaning, you can buy cheaper tires.

I tried 28's. But at 255 lbs, the minimum recommended pressure is pretty high.

We have some roads around here that are chip sealed w/o the benefit of being rolled. It takes a while for the traffic to pound them smooth, well as smooth as they get. Well, it only took a short distance before I missed the 38's. Even though the rear was a dreaded Marathon Plus...

Currently, I have my 38 Marathon(420) on the rear and a pasella tourguard 32 on the front. I'll stick with this until the Marathon is wore out... Then likely pasella's front and rear...

Almost dumped a brand new frame because it rode so rough with 23 tires. Every little bump that the bike rolled over sent an intense jar throughout the whole bike, (and into me). When I switched to 25 tires, it transformed the bike to where it is now my favorite and my go-to bike for long distance riding. With my newest frame, I went with 28 tires. They do not seem to offer any advantage over the 25s, (comfort-wise), so when they wear out, I'll put 25s on that frame too. All my bikes have 25mm tires now.

(The bikes referenced above are all carbon road bikes.)

Nothing smaller than 25s

Really? Which bike was that? I think 25s are a little superior to 23s but only because I can run them 10 psi lower. I had wider rims for a while and went another 10 psi down and that also helped. Other than that, I don't think the actual width makes a difference. I think michelins run slightly wider than continentals too, so apples are not necessarily apples.

I ride 25s, because my frame allows it. I have fit 28 contis on my bike but clearance was so sliver thin, I felt nervous about it and went 25. My next roadbike purchase will have to tick the box on 28 tire clearance which shouldn't be an issue because I'll also be looking at discs in a couple years from now.

my tubulars are 22cs but everyday wheels are 25c that measure to 27 because of my rim profile

At 270 lbs., I think 25's would have to be aired up so they are hard as a rock.
I weigh 250 and use 25's, but I have rather smooth pavement. If you have rough textured chip seal, 28's may be pushing things.

I'd consider 24 spokes to be insufficient, at least on the rear. IF you are a "strong" rider or mash up hills, that strains spokes even more. Remember, when you pedal, you are trying to "unwind" 1/2 your spokes.
However, a little fatter & softer tire would help absorb some of the impacts at least and extend spoke life.
Get the spokes PROPERLY tensioned BEFORE you ride. Maybe you can extend the life of the wheel significantly.

I ride on anything from 23 - 28 depending on the bike and terrain. A think 25's are good for larger sized people and they roll fine...

at 360 pounds I ride 25s at 110 psi (10 psi lower than max recommended pressure) on 32 spoke wheels and love it.

25c is my skinniest. I think it's a pretty good mix of rolling and comfort.

I'm 220...something & ride 23s no problem. I do have 30+ spokes, just don't remember if it's 32 or 36. the extra spokes help especially in the back for sure

I ride 23c on a couple bikes because that's what came with them and I'm too cheap to replace a perfectly good tire. When they wear out I'll replace them with 25c.

25c on my fixed gear.
28c on my vintage road bike.
32c on my hybrid.
2.25" on my mountain bike.

I'm 6'2" and around 245 lbs. I ride 25's on well paved roads, but one bike I commute regularly on has 28's, and I've only had one flat so far.

I'm currently riding 25s which are the OEM tires on my Fuji. I've actually been pretty surprised with how comfortable they have been for me. I'm 195 lbs.
