As a side note, has anyone tried running even higher pressures?
on my old scooter it called for 30psi front and rear. the maximum sidewall pressure was stated at 40psi cold. I put in 39psi as a test and the scooter was noticeably faster and got better gas mileage as the rolling resistance was much reduced. And I ran the tires like that for the rest of the time I had it.

Anyone try that on the BMW? I may have to check what the maximum sidewall pressure is rated at...

I run 39 psi on the front tire and 42 on the rear tire cold they usually give lower tire pressures for a softer ride. I have seen the front go up to 41 psi and rear to 44 psi on a warm day and long ride.

What's the maximum sidewall pressure on the front tire?

 

[Oldscoot]

On my C600 I pretty much follow BMW's recommendations, 35 psi front 37 psi rear. Since the pressures as expressed in decimals I rounded them up. I really wouldn't stray all that much from recommended pressures. Too little or too much can both lead to trouble.

I have to ask....are these tire pressure readings from the TPMS, or are any of you actually using a solid tire gauge to get these numbers? Tire pressure is of great concern, especially riding in the Florida heat and I don't know that the TMPS is accurate considering it seems to offset calculation for 68 degrees. Just curious what the source of your numbers are....

Tire Gauges ALSO can be notoriously inaccurate! The ones that are connected to an air line, and the typical Pocket Gauge, all have a lineal spring that is compressed by the air pressure, to then give a reading. The problem is, the springs ALWAYS fatigue! I take my German MOTOMETER gauge with me to correctly calibrate the pressure when I (or some TIRE TECH) inflates any of my street tires.

Worn gauges read TOO HIGH; it may read 35psi, but in actuality be 25! Especially so with a wide-range gauge, 0-100psi, used on air line inflators.

BUY A GOOD GAUGE!

On my GT's monitor, the readings vary from 31f/36r warm to 33/37 warm. I am in northeast Ohio. Too low?

I prefer 40 rear / 35 front. I carry a 130 pound passenger (don't tell my wife I told you that) once a month. Otherwise it's just me, beating the the tread off "fart pipe" equipped speed demons between lights. I suppose it's because they are easy numbers to remember and aren't far from manufacturer's specs. Haven't felt any strange behavior yet.
By the way, the on board sensor measures 36 & 33 against my gauge measurements listed above.
