The article focuses on the track, but it could make a difference on the street as well.

So. What's the answer? Run the higher pressure recommended on the tire, and avoid the flat spot? Run the lower pressures recommended in the Owner's Manual? Check while hot or check while cold?
Oddly enough, tire pressure has been on my mind lately. I had set my tires to the recommended pressure on the side of the tire. Then I thought differently and set the pressure according to the manual. Since I've done that, my back tire has started to flatten in the middle, but some chattering I was feeling on the front end has calmed down.
Marthy sets his tire pressure when they're hot. I can't see that. Seems like all the recommended pressures, be they by manual or on the tire, would take into account the fact that pressure is checked when the tire is cold.
When I was running twisties yesterday, the flat of my rear tire became evident. I've never felt the rear of this bike start to slide, but I felt it many times on that ride. "Disconcerting" would be a serious understatement.
It was around 90 degrees F, ambient. My tires were definitely warmed up. I don't mind changing the pressure before I make those twisty runs, but they're an hour and half away.
Meanwhile, I commute and ride pretty boring, straight roads with the occasional tight turn. That flat spot again. So. What's the answer?

I'm trying to get a handle on the best pressure for the tires as well. My service tech says 36/42 (cold) even riding 1-up. I'm about 180lbs, but that still seems high, and I'm developing that rear tire flattened center, after about 5500 miles. You'd think that would be a low pressure issue, but apparently not. (Stock Dunlop RoadSmarts. I'm very happy with them otherwise).
Sport Rider recommends changing out the tire when that happens, since I'm rarely on long straight roads, and that flattened center can be an issue on curves. So, I'm looking for thoughts on this. I do NOT want to sacrifice grip, so I'll change it out sooner than later.

Umm wow...new info to me. Well I have noticed a flat spot on my tires, and im only at around 2500 miles on the tires. I keep my psi around 32ish, however I unfortunately live in a pretty flat area so a lot of my travel is on highway, would that be why?
