Agreed… A 28 is way too rational.
Durano 28s say 85-115psi. I’m running them at around 85-90 at the moment.
Oh rad, I thought once you got up into 28’s they all went down to like 90psi max, not sure why I thought that though, haha. Keen to see how the 28’s go, then 
90 to 95 for me on the Duranos, but I only weigh 72kg. I would typically run 23mm Gp4000’s at 115, but havn’t had em on a bike for a while since my wider tyre evolution.
Wait, so higher pressure for a lighter rider? I am confuse.
too heavy and i reckon you’d have chain stay rub on my frame with even a 25c
i know people love the bigger tires cause they are more comfortable but…
the veloflex extreme and carbon combo i run ( both are 22c ) have latex tubes and i run em at 95/100psi…
they are very supple, if not over inflated, both fast, grippy as all hell ( in the wet too ) and very comfortable…
they do have a couple of features that make them not for every one… they cost $90 each, you have to pump them up every single ride even if you ride in the morning and then 6-7 hours later and the rears are toast in 2000-3000kms
That is very high for your weight.
This stuff has been posted before, spirito started a thread on the topic earlier this year. It makes a beneficial difference to both comfort and speed.
+1 Steph…
Even when presented with such good and useful information most people don’t learn this lesson very quickly, didn’t you know tires roll faster with lots of psi… 
Im 81kgs running 23mm tyres, WTF kinda pressure is that!
You should be looking at the kinda pressures I’m running. 90-95 front and 95-100 in the back depending on the conditions.
The charts weights are wheel loading per wheel… I it’s you, the machine and your gear… Total weight distributed over each wheel.
Typically 45% front and 55% rear for a roadie
Your a bit lighter than me but my bikes a bit lighter
What about a sw8 fixie??
I guess that depends on the presence of aerojokes.
Haha just pump the tires up to 120 so you can be a lazy Cnut and not have to do it again for a week.
Grip is not much of an issue with a sweet fixie and it it’s a real fucking track bike with drops and all the level of comfort is gona be minimal any ways
Time to trade up to fatties: Giro Tech: Rise of the 25c tire
It’s the way of the future.
ha!!!
True. Anyone still riding 23c or skinnier and not being paid for it is really vain or enjoys the extra vibratory pain in the saddle area and for the hands. I will excuse Kanye as he rides Tub’s and they are usually (not always) a lot more supple/comfortable than clincher tyres given the same width.
How long before road UST tyres are available in 32mm? I have a wheelset waiting.

Serious question Spirito - RE: 23’s… wouldn’t this depend on the TPI count, quality of materials and surface contact area of the tyre too?
I changed from running average 25’s to quality (pricier) 23’s and I reckon the ride improved heaps.
I think you answered your own question: all else being equal, the wider tyre will give you a better ride. So let’s say you have a 20c and a 25c that are identical in all ways but width, the 25 will be more comfortable, will roll faster etc. It’ll lose out in aerodynamics, but that’s negligible even in a wind tunnel.
But as you pointed out, a quality 23 is usually gonna be better for ride quality etc than an average 25.
any thing over 300tpi is gona feel pretty nice.
bet these are pretty nice 25c tires
Why haven’t tubeless taken off in roadies to the same extent as MTB? Something about not working as well at high pressures?
