Finding the right tire pressure

“summary, lower pressure doesn’t slow you down on smooth asphalt, and it makes you faster on rough surfaces. So it makes sense to err on the low side when choosing your tire pressure for mixed-surface rides. Of course, you don’t want to go too low, either.”

Guitar players will recognize this standard as cut from the same cloth as “I want my strings set as low as possible but not so low that they buzz”.

[DHallerman]

In other words, your tires’ maximum pressure (or even close) is rarely the best pressure.

Maybe for the high pressures of road tires that is true but for MTB tires the difference between the minimum and maximum pressure is huge. I find it hard to believe there isn't a small gain from running 95 vs 75.

According to the graph below from bicyclerollingresitance (https://www.bicyclerollingresistance.com/specials/grand-prix-5000-comparison#drop15), at 23 mm, 25 mm, 28 mm, and 32 mm of tire width increasing tire pressure actually lead to lower watts.

Sure... because it's a steel drum.

Josh from Silca's marginal gains podcast has multiple episodes on this topic.

Silca also has a pressure suggestor on its website.

Needless to say the conclusion is bigger tires at a lower pressure are ok.

According to nmrt's chart, using a 25mm tire and increasing tire pressure from 80-100psi, I save a whopping 1 watt.

Ain't worth it. I'll take the better ride.

Every now and again I have a "magic" ride that is so fast. Far faster than usual.
Equipment, nutrition, and fitness being equal...I often attribute it to tires being perfect.
At the same time I remain mindful and aware of the risk of pinch flats on clinchers.

[nmrt]

That's exactly my take on from the chart too -- comfort!
While losing an insignificant amount on the watts due to the wider tires.
