What Pressures Do You Use?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

What Pressures Do You Use?

Everyone seems to have their own ideas on what pressures run best on their road bikes. I'm curious to know what sort of pressures other riders are running, based on their weight and such. I know different surfaces make differences, so base it off of your general road rides.

Where do you find to be you optimum pressure for your weight and bike weight, as well as the size tire that you use on your tubed and tubeless setups?

This chart tells you

I haven't figured out my weight distribution, but I've been using 100 lb rear and 95 lb front on 25mm road tubed tires. Per this chart that may be too high.

I currently use 700x25C Tubeless tires, I am 185lbs, and I run 90psi Front and 95 psi Rear. Hbu?

And it seems everyone has a chart and different reasons. I'm just looking to see what most people are actually using.

I personally go for peer pressure. I've found that's what works best.

Sometimes pee pressure is a big factor.

Too much coffee.

I weigh about 155, put about 100 psi in both tires at 23mm. Once they wear out I'll go 25mm and about 90 psi.

anybody know how many lbs are lost removing a shraeder chuck? just a quick burp when it comes off. I've always figured at least 5lbs but maybe 10? maybe nothing cuz the air is actually coming from the pump hose, not the tube valve?

I'm 205 pounds, riding 25C tires. I have run 75-90 PSI front and 80-100 PSI rear in the 2 different brands of tires (Michelin Lithium 2 & Continental Ultra Sport 2). I had worked my way down to the 75 and 80 PSI but started having flats so I went back up to 90 and 100 PSI but that didn't help. I have new tires ordered (Continental Grand Prix GT's), I'll start out at 80 and 90 PSI on them and see how it goes.

The road conditions and the rider weight have a lot to do with the choice.

I'm about 155 lbs, use 25c tires and inflate both front and back to about 100 psi.
Crappy PA roads.

I was trying 80F/90R in my 23c last week...no flats, but too squishy feeling for my liking. I'm currently around 190lbs. This week I'm running 85F/95R and two flats, but not pinch flats, just some bad luck with thorns.

Max PSI I run 28c at 120 psi, stiff but still more comfortable than a 25c @ 115.

Second half is correct. No loss, only from the pump. My pump hose eats 4psi upon insertion.

You run 28c's at 120psi ???

Just get solid rubber tires at that point, damn!

I went from 25 to 28 (Panracers Ruffy Tuffy) They reccommend 90 on sidewall max 120. 90 was like rolling in mud. It doesn't make sense to me that I would run 28's higher than 25's but I think what it comes down to is I'd be better off on 25's.

To get 28's like 25's takes more PSI (I think) because there is more sidewall give with less. I hope that makes sense.

I guess I'll add that I'm 130-140 lbs
