What tyre pressure does everyone run? [Road]

[Tommyk]

I am 88kg and still run tubes but I still enjoy high pressure tires. I run around 110 and never let it go below 90. I enjoy the feel and the buzz of the road. I did try 75-80 but once I had to hop over a pothole and I didn’t like the squishy feel

That is wildly high

Two pairs of Hunt wheels, both ~50mm one set running 28 mm GP5000 AS, run at 65PSI, the other standard 28mm GP5000 S TRs at closer to 70PSI. Weight ~75KG.

Whatever the SRAM app suggests. I find this works really well for me as a balance of speed and comfort versus the others such as silca.

[Back2Basics]

Thanks. It seems others are in this boat. I’ve been following the Silca calculator but that appears to be around 10psi (or more) higher than Silca. I have a 120km ride on Saturday, might test out something lower and see how it goes.

As far as the SRAM and Silca calculators go do not seem to follow similar metrics. The results of the two do not ever come close for me.

The two simply offer different options: Silca’s tire pressure calculator offers a selection of road surfaces and the recommended pressures vary significantly between them. Unlike Zipp’s, it doesn’t care about inner rim width.

As with any tire pressure recommendation, I view these as a starting point for my own experimentation.

Well, that is the difficulty between the two. Trying to keep parameters as close as possible yields very different results since the metrics cannot be made to be more similar to each other. It does not at all seem like different options more than making a calculation based upon different inputs. The SRAM calculator dials in the tire/rim interface more vs Silca and road surface.

Silca’s pressure recommendations vary quite a bit depending on the road surface conditions and your average speed (I reckon that’s what Silca factors in when they want to ask you whether e. g. you are a Cat1/2/3 rider).

I find that depending on the surface roughness I get different harmonics at different speeds.

I just accept that each includes different variables and since I figured out what pressures work for me and the roads I am riding, this is no longer a big issue. E. g. Silca’s speed selector is less useful to me in practice and the distinction between wet and dry surfaces makes more sense.

But to each their own. As guides they all work IMHO.
