I never said if someone runs less than full pressure they'd slide off the road. Please point out where that was said. It wasn't stated, suggested, 0, nada, didn't happen.
You keep referencing these "tire engineers." I've told you, repeatedly I might add, that I have spoken to tire reps before, multiple. I've spoken with Bridgestone, Metzeler, and Pirelli over the years and what they told me and what you are saying as "Tire engineers" doesn't match up. I've attended many track days, spoken with tire reps, worked with rider coaches, mechanics, and riding schools. Every single one of them has told me to adjust PSI to conditions. And those are temps, road surfaces, riding style (commuting vs. twisties), suspension, weight of the bike, weight of the rider, etc. It's variable, much like suspension settings such as sag, rebound, compression, etc.
A few of us have told you that there is a gross weight rating on our bikes. And that 36/42 is a max PSI rating for these tires, that means maximum NOT MINIMUM. We've also told you that there is a relationship with PSI and grip. We've also stated that none of us believe track PSI is what you should run on the road. So we are now just going in circles so that you can keep trying to be right.
I stated what I run. A few of us have stated also, to learn these things for yourself, don't believe us, or you. Do your own experimentation and learn about PSI, and what it does to grip. My experience says that 36/42 is for when i have my bikes loaded with gear and/or when I'm slabbing it. Over 90% of my riding is hard twisty riding, with the additional 10% being the track. When specifically hopping on one of them to corner, I drop the PSI in both my tires, slightly, to gain some additional grip, which I do in fact get, and what I've experimented with for many, many years, as well as working with tire mfr's to find an ideal setting for my riding style, conditions, speed, etc. You indicate that will give a decrease in performance and to me that is an outright lie. Perhaps you should take your own advice and try it instead of stating a one rule for all that many of us have told you just doesn't work. You are hell bent on this so you go ahead and continue on with it and if that works for you, great. I will say just about everyone here is going to have some experience. If they don't, they've got bigger problems than this jumping on a high powered bike as their first and not knowing what they are doing.
Yes I run lower PSI than the max rating. My tires do not deform, I get an INCREASE in performance and the only negative is slightly less tire life out of the rear tires that I am happy to trade off to gain additional grip. Running lower pressure will not cause you to slide off the road, or the tire to explode or any other such nonsense. Even mentioning that was completely stupid, inaccurate, and slander and I don't think you understand the subject as your comments and recommendations go against everything I've been taught and practiced. There is a max weight and max PSI for a reason.
Great post, its nice to see someone talking some sense.
