    Yet oddly enough, for a Versys 1000, they told me to run 36/42 if loaded and 32/38 if riding solo with light load ......

    here is a list of their tires and recommended pressures for most bikes

    why do you want to know. I'm not sure I trust you with that information.

    I'm not sure how that could be true since a 650 lbs. bike is going to need more air pressure in it's tires than a 400 lbs. motorcycle. You will also need to adjust for the load you're carrying and the size of the rider and/or pillion.

    If these far lower than factory-recommended pressures (36F/42R) make so much sense, then is it safe to do the same with a car? Instead of the recommended 35 psi, just run 18 or 20psi cuz 'performance'?

    I'm not sure everyone here is aware of how tires and their pressures affect them. Lower pressures cause a bigger contact patch, which will alow for not only more friction between the road and the tire, but will cause the carcass to flex more. What this causes is heat in the tire. Typically the lower pressure you run, the more heat you get into the tire. Touring tires are generally filled up to that 38-40 psi mark because you have a smaller contact patch, which caused less wear and less of a harsh heat impact on the tires. At the track, on a 90 degree day I'll run my q3+ at degrees cold, and a q4 32 cold. Tires typically have a 4-5 psi gain cold to hot on the track, and a 2-3psi cold to hot on the street. If your speed and ability level isn't high enough to keep a tire warm then, yes lowering the pressure ie dangerous, but generally lowering pressure will give you more performance.

    I'm no expert, but yes understand how tire pressures work. I typically run 34/36 or 36/36 on both bikes unless I'm carrying cargo and then I'll bump the pressure up on the rear. Lowering the pressure to increase contact patch and heat has a limit of diminished return. Too much flex and heat can cause greasy tires that break traction unpredictably. I can tell within a couple corners if I my tire pressures are within an acceptable range.

    My experience, and that of many 09 owners say that it is. So does Michelin and Dunlop it seems.

    Many owners of my car model use lower pressures for comfort, and some say handling is better. But cars generally aren't as pressure sensitive as bikes.
