You don't need to pump to such high pressures, and there extreme stresses at the contact patch are distributed over more area, which is good for both durability and wear life.

Spring rate against a flat surface doesn't necessarily scale the same as spring rate against narrower deflectors.

Unfortunately there's not a lot of data out there on how breakpoint pressure scales across sizes of similarly-built tires.

Yup. Even TdF riders stopped using 23mm tires. And keep in mind that these guys are like 150 or 160lbs.

I have a whole bunch off bikes, some of which were rescued and dilapidated. keeping good tires on them is costly and time consuming

"Nobody cares," because it's not "ruining" anything.

What is the maximum pressure rating for the rim and the tire (there's a reasonable chance it's lower than 140).

For all that weight, you really should be using wider tires.

Given your proven "expertise", this opinion is very credible. /s

Thank you. I'm not racing anyone, so "speed" isn't an issue. Neither is road vibration.

Regarding whether 23s at 140 psi "work" - a lot of things "work". Carburetors and points/condenser ignition systems "work", but EFI and electronic ignition work better. Cathode ray tubes "work" as televisions, but LED screens work better. Burning wood "works" to heat a house, but more modern methods work better.

So, yeah, 23s at 140 psi "work", but wider tires at lower pressure will likely be faster and more comfortable, as well as longer wearing and less prone to pinchflatting. You pays yer money and you takes yer choice.

Good lord, you start a thread about not being able to pump up your tires because they have so many patches you think they're going to blow and you post this?

You're obviously not riding the 23s just fine or you wouldn't have to ask this very weird question about ear protection.

TdF riders with a gross vehicle weight of over 300 pounds? Don't think so.

This claim is so vague, it's meaningless. And comparing your weight with professional riders is absurd. You are less trustworthy than what people might be seeing on TV. Anyway, are people on TV really claiming they are using wide tires or is that just blather you are making up?

Note that most of the riders are using tubular tires.

https://www.thegeekycyclist.com/pro-...oad-bike-tires

Like the previous years, the majority of the teams will be riding 25c tubular tires with pressure up to 160psi, depending on other factors such as road surface and rider weight among others.

This year, we’re seeing a number of teams running tubeless and clinchers which is a departure from the general consensus that tubulars are preferred for racing.
https://www.bikeradar.com/features/t...our-de-france/

As of Friday, four of the six road stages thus far in the 2017 Tour de France have been won on 26mm tubulars. While 23mm was the pro standard not so long ago, this year 20 teams are using 25mm tires for non-time trial stages, and the other two Specialized-sponsored teams are using 26mm rubber.

Bike Tires Ridden at the Tour de France 2022 (thegeekycyclist.com)

And the bikes are much stiffer these days, with the carbon-fiber frames, especially the aero frames, and the aero rims — like when you're running like a 50mm-section rim, which is quite deep — all that stuff is stiff, so the lower pressure helps provide more comfort for the rider.
Why Tour De France Tires Keep Getting Wider and the Pressure Lower (businessinsider.com)

I'm riding a steel framed bike, so, for me, 23C at 140 psi works. If it doesn't work for you, that's fine.

Nah, you see, all those people on multiple news sources are all lying. All those pictures showing tires obviously wider than 23mm? Photoshopped. EVERYONE - hundreds of journalists - ALL of them lying for "Big Gravel", and not a one of them is willing to stand up and say, "IT'S ALL A LIE! THEY'RE ALL ON 21MM TUBS AT 180 PSI!"

Big Gravel sent their leg-breakers to all the cycling news outlets, to tell them, "Nice cycling website you got here. It'd be a shame if something was to happen to it...."

Sure, use ear protection.

But you need to learn how to properly install a tube/tire.

Their equipment is visible in plain sight. You're claiming that commentators, support staff, racers, and basically the entire French public are part of a conspiracy being controlled by, I guess, American gravel race organizers who for some reason want to help tire manufacturers sell product that costs more to make and lasts longer?

Comfort isn't an issue ....got it. I'm not racing anyone or anything either. I just like better performance and more comfort. Wider tires and lower pressures work excellent in this regard.

A lot of people on this site would consider 25c to be pretty narrow...

Sure, but we're speaking contextually: Larry is suggesting that the tires they're using are narrower than what they're claimed to be using.

See the quote linked above a couple times:

He didn't say that. You inferred it. Larry just said "TdF riders run narrow tires at high pressure." You agreed that 25c would be considered narrow by lots of folks on this site. And I quoted a site that showed that indeed, the majority of teams are reported to be running 25c tires.

Roling resistance and absorbing bumps are measurable things. Your preference may be otherwise, but it's not like you're operating under a different set of physical laws.

But, ride what you want. I know I do - everything from 22mm tubs to 28mm clinchers.

Larry said "narrow" (not "pretty narrow") but who really knows what he meant. And the TdF riders are mostly using tubular tires. And the riders are whole-lot lighter.

Larry's claim is meaningless nonsense. Don't dig through that pile to try to find nuggets of meaning.
