Vitus Vitesse EVO Disc Review – Speed Machine indeed!

I've been riding my first road bike for 2 weeks now and was wondering what people would recommend for tyre pressures.
I'm running 25mm Giant Gavia Race 1 Tubeless Tyres, I weigh around 72kg and have been running 100psi. It seems to be fine but a bit more dampening of the rougher roads would be nice.
Does having tubeless change anything? Simon Richardson was saying that he runs 80 front 85 rear on his 25mm tyres, would this be a good option? Should I just play around with different pressures?
Any advice appreciated!

Tubeless tyres will generally run slightly lower pressure than equivalent tubed tyres because the sidewalls are a bit more rigid.

Here is a diagram showing pressures to give the 15% drop that Duck mentions for various rider weights. Note that the weight is the weight on each wheel.
With tubeless it is also possible to run a bit lower pressure because you don't get pinch punctures.

After reading this article I would be hesitant to run any tubeless tyre over 60 psi though.

I used the GCN video as well as the chart Sharkey linked as a guide for my 25s. I weigh 68kg, I normally put about 80 rear, 75 front but that's with tubes. Tubeless would be more like 70 and 65?
I know that's more than the chart recommends, I'm just being lazy and slightly over-inflating to allow for some inevitable pressure loss over time I only check pressures every fortnight or so.
You'll feel a big comfort improvement dropping ~20psi.
