I'm narrowed done my search for a set of clinchers for my Koga Miyata. I will be getting 700C x 23mm. I am not sure if I should get Schwalbe One (with inner tubes) or Schwalbe Pro One tubeless

The bike is my 'Sunday' bike that I will use for long rides. Roads are average with potholes, debris etc. So I'm after tyres that will be fairly puncture resistant, yet roll fast and are comfy

On my commuter, I have been using Schwalbe Durano Plus (700C x 25mm) for a few weeks and they are ok (no flats are ride ok), but I want to try something different for the Miyata

Pro One's get rave reviews but they are tubeless. So you need to use sealant? .... And if you get a rip, do you have to bin them?

Sealant yes

If you get a rip on any tire you need to bin them. When the fabrics compromized the tire is dead.

I've been on tubeless for several years now and I would never use tubes again. They do need regular maintenance, like topping up the sealant every month or two and the valve stems are a pain to remove if you need to put a tube in for an emergency. However, the benefits of tubeless w/sealant far outweigh fixing flats on a regular basis. The ride quality of the Schwalbe One tubeless (haven't tried the Pro version yet) is amazing.

If you don't have tubeless ready rims, it may be a hit or miss to get the tires mounted and sealed. Your rims will need to be taped with tubeless rim tape to seal the spoke holes and you need to buy valve stems. I've had varying rates of success with non-tubeless ready rims. Some mount up and inflate easily and some have needed a strip of old inner tube in the rim to fill the gap between the rim and the tire bead.

I've nothing to say about the Pro One, as you can barely even find them, but I do have a few months of experience with the old One tubeless (and the Pro One and the One are made out of the same compounds.) That said, anyone you tells you the Schwalbe One tubeless has any amount of puncture resistance or respectable longevity is not being truthful with you. The One is a very fast rolling, grippy, maximum performance tire. But it has absolutely zero flat protection built into the tire (it's all left up to the sealant) and you will see visible treadwear after even the first 50 miles. I had a rear showing cords at 1,000 miles. And by that 1,000 miles, the rear tire was as much superglue as tire, as the debris cuts would continue to grow and grow unless glued. With the Pro One being even thinner and lighter than the original One, I can't imagine the tire life and durability being any better.

I regularly tell people, it's a fantastic tire if you can somehow get them for free.

EEK .... in that case, I think I'm going to get Continental Grand Prix 4000S II instead. One of my friends uses them for century rides and speaks highly of them

I will admit that the Schwalbe Ones are more prone to cuts in the tread than other tires, but they seem to improve after about 100 miles. They are expensive tires and I wouldn't recommend them to anyone who can't afford to throw out a tire before its worn out. I had to trash one on the first ride after running over something that put a 10mm cut in the tire. Although, I'm pretty sure no tire would have survived that cut.

My experience with One tubeless over the past couple of years has been very good.

Yes, the wear fast; I get about 1.2k miles out of a rear, and that takes them low enough that a brief lockup in the rain will bare cords, which is a scary place to be. I understand Dr. Isotope's concerns for ProOne durability, but it's conceivable the weight savings came from the new MicroSkin carcass, bead, and sidewall rather than the tread, and so will wear no worse.

On the other hand, though, the One are excellent performers, with great grip and feel. The weight is kind of high, but I don't notice it to hamper reactivity or speed, so really the tires have no deficits insofar as I am concerned.

Absolutely use a tubeless-ready (TL) rim for road riding. At road pressures, not having the bead secure is very problematic, to say the least.

Use of sealant is not usually necessary. It's cheap flat insurance, but is not necessary for airtight sealing in most cases. I have run my Ones without sealant on AC rims (but regularly use Stan's sealant), and currently have a pair of Schwalbe S-Ones without sealant on AC rims, which haven't rolled more than 1000 meters, but have been holding pressure for almost a week now, and the S-One shares the Microskin Tubeless Easy carcass of the Pro One, so I'm not sure I'd make much of Schwalbe's assertion sealant is required. But again, it's cheap security against flats, so why wouldn't you? I will add Orange Seal to my S-Ones when it's time to hit the road.

Lastly, regarding cuts, punctures, and durability, I've only had one puncture I was aware of while riding, and which self-sealed, and one which self-sealed that I didn't even know happened until I was sometime later inspecting the tire and found the plug. That's over the course of five One tires (front and rear) on some of the worst roads in the nation, here in urban SE Michigan. The One haven't proven any more susceptible to cuts and punctures than any other high-performance/racing tire I've used over the years, including Michelin Pro, Conti GP A/F, Panaracer Type A, Mavic Yksion, or any of the others I'm sure I'm forgetting (I love rubber! I'm a bit of a tire junkie!). My point here being it may be an issue of relative comparison, and if one is not accustomed to race tires...
