At the track we run them even lower but I do not recommend those pressures for the street.
Thanks for all of the info Patrick! Everything helps.

Are you dragging knee during your 30 minutes of hard riding? You realize that overheated tires start to slide too, right?

I don't drag knee on the street, I mostly practice backing it in and hard breaking under the u-turns that go under the freeway, and I loop over and over til I'm done and go home. I practice control, so I actually make my tire slide. I tried backing it in at full pressure and I almost lost it because it stepped out faster than I wanted. The low tire pressure gives me a much better feel of what my bike is doing.

Maybe you should use tire warmers. When do you get to practice right turns?

I run 36/36, Pilot Power front (going to BT016 when its time) and BT023 out back.

If I plan on being a goon, I'll let them both down to 34, but I don't ever push the bike too hard....waiting on a track day

TC Jester just north of I-10 has a slight cloverleaf too

To add to the thread, I run 28 front / 32 rear on the 250. I guess the higher tire pressure doesn't pertain to the lighter bikes.

Just as there are different tire pressures for cars, the same goes for bikes

As well as same goes for different type of tires depending on the carcass and tread compound.As well as the weight of the bike and then factor in rider preference.Depending on what you feel you can change tire pressure to fit your needs. This is a bit more advanced and people who are not remembering to CHECK their pressures then they are probably not needing advice on all the variables that determine what tire pressure they should run. I am assuming Patrick was trying to drop a reminder for people to check their tire pressure "possibly due to the cooler weather" and giving a good baseline number for people who are not changing their tire pressure a LB one way or the other depending on what ride they are going on It is truly amazing how many people haven't EVER checked their motorcycle tire pressure since they bought their bike.
