Tire recommendation for a 150-200km challenge
Hello,
I'm looking for a tire for a 150 to 200km challenge. I'm training 3 times per week on shorter distances (50-100km) aswell. The bike is a TREK Domane AL2 which came equipped with 25mm tires when I bought it (2021 model) and is now offered with 28mm as standard (for 2022). Stock tires are ok but I discovered cuts in the rear tire so it may need a replacement.
Most important for me (in this order) is
- ride comfort and feel
- versatility: smooth/rough roads, dry/wet, summer/winter riding -even if I will mostly ride in the dry, on average roads and about 5 to 20°C temperatures (=40-70°F)-
- durability
- rolling resistance
- weight
Do you have any suggestion? Do you think it's worth switching for 28mm tires (rather than 25mm) and latex tubes?
Many thanks,
Eric

Everybody seems to like continental GP5000. If your bike will take a 28mm tire, there really isn't a penalty over a 25 and there are some marginal benefits.
But I don't see why you would ride anything different than you would on any other ride for something like a 200k. Longer rides than that generally involve some amount of riding in the dark, and larger tires have a benefit for that because they are a little bit more robust. Granted, 28mm and 25mm are very close to the same size. But I would expect to ride 150km-200km in daylight.

I will ride 1/4 to 1/3 of the time in the dark in the next few months. I train after work and it's getting dark quite early. I'm not talking about the 150-200km challenge here, just for training.
I'll take a look at the Conti 5000 and see the other options available but any feebcack is welcome

GP5k is a safe choice, but there are lots of other good tires. Since I go through a lot of tires, I watch for good deals and stock up, or maybe throw in a set of tires to get free shipping.
Regarding width, I prefer 25mm tires most of the time, but a lot of people seem to like wider tires, so maybe you should get the 28's and see if you like them better. If I only had one bike, it would have fenders, so if I had your bike, I would run 25's.

I've been using the Conti 5000s. I've got tubeless 28 mm on my distance bike, tubed 32 mm on my commuter. The tires on the commuter bike are pretty torn up, which is not surprising considering the streets I commute on. By some miracle, I haven't had a single puncture on the distance bike (knock wood). Anyhow, they've been good tires.
For day-to-day riding I would not bother with latex tubes, but I might use them for an event. Or those weird thermoplastic innertubes, perhaps.

Concerning speed and rolling resistance are the 25 and 28 equivalent?

You don't use latex tubes because of the need of re-inflating them often compared with butyl or what would be the problem of latex tubes for everyday riding?

Thanks, I forgot to mention I have 2 bikes. Generally I use an other bike which is equipped with disc brakes when it rains and the Trek (rim brakes) when the weather is fine. I live in Belgium so the weather can change very quickly but it doesn't really matter I would rarely start my ride with the Trek + fenders.

For me it comes down to feel. Most of my training rides are 50-100k on pretty good suburban roads and include some hard efforts, so I prefer the feel of narrower tires for that kind of riding. At 150-200k I might run a wider tire or I might not. A solo 150k would almost certainly be on 25's, but I might go much wider on a casual club 200k. There's no one right answer all the time. I say try the 28's. You can always go back to 25's if you like them better. Tires don't last forever so you can try a few different ones out. FWIW I've never seen any reason to try latex tubes.

I think the consensus view is that there's no significant difference in rolling resistance or speed between 25 and 28 with the same quality tire. The pro teams still run mostly 25's so I assume there's some benefit to the narrower tire. Acceleration maybe? I don't know. All the teams have disk brakes, so there's no reason for them not to run wider tires if there was no downside.

I just mesured the outer width of my wheels which is 23mm. Is there a correlation between rim width and tires width to ensure a proper "fit"? What would be the ideal tire size VS rim size?

Rim manufacturers go by the internal rim width, and each manufacturer will state a range of compatible tire widths. There's not necessarily an optimum width except with aero wheels, which are often designed for best aerodynamics at a specific tire width.

If the Bontrager R1 Hard case Lite is the tire I'm thinking of, you are really going to like a Conti 5k. Not only are the Bontragers a little slow rolling, but one of them let loose at the bead when it was still fairly new. Long ride too, 325km.
The other annoying thing about that tire was that the 28mm was exactly the same size as a 25mm

For a double metric century or less just ride what you normally ride. At about 200km and greater comfort beats weight savings all day, so wider tires makes sense as does fenders if it all fits, otherwise don’t worry about it. I did a 300km at the end of 2019 on some older 25mm GP4000ii I had and they held up fine except for eating a nail at about the 180km mark but I don’t think any tire would have stopped that.

Panaracer GravelKing is my tyre of choice, but yeah GP5000 is also a very popular choice and I have ridden with people using that tyre and not getting any punctures during a 1000k - though at the same time people do get punctures with them so I guess it comes down road condition and luck.

It's not a bad idea, but I'd just get a nice set of tires in whichever size you think you will like better. 25's will feel a little more lively, 28's a little more cushy, but the sizes are pretty close. I definitely would not get another set of the Bontragers in 28.
ETRTO publishes a table of acceptable rim and tire width combinations, but Jan says "rim width doesn't really matter". In either case, your 17mm rims are fine for both 25 & 28mm tires.

I discovered a rim/tire chart and concluded just that 28mm are perfectly fine on a 17mm rim. I just want to avoid the "light bubble" effect with a tire that's so big it "rolls" on itself and creates too much drag. But we are talking 3mm here, the difference will be minimal with the 25mm tires.

Do you guys run tubeless tires or keep your tubes? In MTB and gravel I see the benefits of going tubeless but I'm not quite sure for the road. Have you tried a combination of a thinner tire in the front and wider in the rear? Let's say 25/28mm? On motorcycles and many vehicules front tires aren't as large as the rear ones but I don't know if this rule makes sense on a road bike.

Some people tell me that a lot of long distance riders run tubeless because flats are no fun in the middle of the night. I don't think flats are fun at any time. I'm a bit reluctant to run tubeless on smaller tires. I'm set up to go tubeless on my road bike with 32mm tires, but I haven't done it yet.

A lot has been written on road tubes vs. tubeless. If I were just starting out and only had one road bike I would probably go tubeless, but at this point in my life it's not worth the effort and expense to switch over. Most of the randonneurs I know run tubes, but I see more tubeless setups every year.
I don't know anyone who intentionally uses different tire widths on a road bike. I guess there's no reason not to if you had different clearance front vs. rear or some other reason it made sense. I carry a lightweight 23mm tire as a spare sometimes, but that's different.

I'm confused. Is this whole thread about what tires you should use to train for the event, or what you'll be riding on the day?
For training, it doesn't really matter. Just get your miles in.
I think most people are responding to your title, which implies what you'd be riding on the day of.
I actually did this on my first brevet bike. Not for performance reasons, but the frame didn't have much tire clearance and the front wheel had a hop, so a 28mm rubbed and squeaked. I fixed it before too long.

Just a little feedback concerning weight savings. Setup with GP5000 + latex tubes will be exactly 400g lighter (in total) than the stock one, for the same tire width (25mm).

Just a quick question: do you guys use tubeless tape to prepare the rim before installing latex tubes? is there anything special to do around the valve hole to avoid damaging the latex tube?

The big problems I had with Vredstein latex tubes was either getting pinched during install or afterwards, so you ride 1500km and bang it goes, without anything external puncturing it.
GP5000s are great tires, though, even tubed they were ridicilously reliable.
