Almost the same as me (82 kg on 2.35s: 28/30 recommended, 19/20 actual).80kg, 25mm rim, 60mm tyre, XC riding, Mixed terrain, Mixed conditions.
27f 30r !
My normal pressures are 20f 22r and 22f 24r if it's rocky.
I tried the higher pressure on my Following...hell no. The pressures were way too high. The bike was chattering so bad on the way back down. The rear tire would skip when braking hard.Played with that earlier today.
At 145lbs (no gear)...its telling me 23 and 26 psi for 2.35 and 24mm IW rims and 20 psi for 2.6 and 30mm IW rims. A few PSI higher than I usually run. I'm willing to give it a try.
I did mixed and dry conditions.
Every guide I've seen recommends higher pressure in the rear (and I agree, a bit of oversteer is way preferable to washing out the front tire in a turn).Most guides recommend higher up front and lower out back
I bet if you put in rocky, enduro, pro you will get a number like that out of this calculator.Just raced the 50 mile WOR last Saturday. I was able to absolutely slam the descents. Running a bit more than 30psi on 2.25 RRs, it's simply what's needed to prevent pinches and rim impacts on extremely sharp and loose terrain. I suffered a bit in some turns, but I watched a guy in front of me launch into a sharp rock garden on the 2k descent and he flatted right away. I need to be able to finish the race and bomb the descent. Lots of people find this out the hard way on this race, unless they are running big plus sizes, in which case they are slow and and far behind anyways.
