Zitat von Ralfyrich im Beitrag #46 I prefer the expression "educated guess".  It was hardly rocket science! P.S. I rather felt the OP should do his own research! Chris

BMW and all manufacturers list a very generic rating. It is most likely for liability purposes. I would suggest that someone with a question should start somewhere near those numbers and move up and down a little bit until they find what feels good for them. I intentionally run a bit low, for better grip. I also do not believe that I can tell a 2 psi difference or less. Just my 2 cents.
How do you expect for me to KNOW my limitations when I haven't even MET them yet?!

I hope this isn't hijacking this thread. My R1200 rs sport se has a TPM that has automatic temperature compensation to provide a readout which indicates the pressure as though the temperature is 20 deg C

Zitat von Varnish im Beitrag #53 On the 1250, I am fairly sure that it is not temperature compensated. Mine read higher as the tyres heat. The handbook says to ignore that as it is within expectations as far as I remember.

Zitat von himoverthere im Beitrag #54Zitat von Varnish im Beitrag #53 I also notice that my tire pressures show on the display of my 2016 R1200RS increase slightly as the tires warm up. Maybe about one or two PSI. That increase seems reasonable to me. The important thing is that the pressure reading doesn't decrease while you are riding.

Curiouser and curiouser! My 19 plate R1250RS reads the same throughout a ride but when I stop for a while the pressure reading when setting out again will be lower. My 13 plate F800GT on the other hand does show higher readings as the tyres warm. 19 Plate R1250RS Exclusive with "bells & whistles" & full colour matched luggage |

Zitat von Varnish im Beitrag #53 Since Fred Flintstone took to the roads, we learned to check our tyre pressures cold with a “reliable gauge”. Nothing has changed. Check ‘em cold and enjoy your ride. All these sexy dash devices are tweaking the data and some poor souls are getting caught up in the nonsense. It’s not the “truth”. The only thing the dash is good for is giving you a warning lamp when you get a slow-ish puncture. Having suffered one catastrophic puncture - something no repair plug could fix - I can say that I felt the bike squirm under my arse before the warning lamp appeared.
Carpe Diem!

Zitat von Boxerboy55 im Beitrag #57 I largely agree with you Pete. I have a mains compressor with decent gauge which I use to check and top up all my vehicles as necessary when cold. I do appreciate TPS as an extra safety feature but, of the three punctures I can recall, none has put my safety at risk. The change in handling alerted me. However I suspect that I might have spotted the problem earlier and thus had more options for effecting a repair. A friend with a GS got off the channel ferry and spotted a puncture via TPS as he disembarked and before he got on the motorway. He was able to find shelter at the port and undertake a repair rather than be stuck on the hard shoulder doing the same.

Zitat von Freddyfruitbat im Beitrag #44Zitat von TriangleRider im Beitrag #43Zitat von duccrazydave im Beitrag #39Good video that explains why "close enough is good enough" for me on my street bike. Since the dawn of time? Not hardly. Those pressures weren't commonly used on motorcycles until fairly recently. None of my Motos until my 2014 BMW R9T recommended pressures anywhere close to that. Low to mid 30's was common. As an extreme example, my 1973 Norton Commando owners manual gives tire pressure as 28/30. Most of the Japanese 4 cyl bikes I owned from the '70's-80's showed pressure in the same range, maybe up a couple of pounds. I seem to recall the the TP per the manual on my '01 Ducati 996 was 34/36. The first time I saw the recommend TP in my 9T manual, I thought, "You gotta be kidding me!" Sure enough, the rear will "step out" with little provocation in the twisties at that pressure. It's quite planted at 34/36. Same is true of my R1200RS. Running at the recommended pressure makes it skittish in the twisties for the way I ride. Like the 9T, it feels "planted" at 34/36. If you plan to push the bike hard, the only way to know what is the best pressure FOR YOU and the way you ride is to try different pressures and see what works best. In my experience, less than factory-recommended has almost always worked better for me but, of course, that doesn't mean it will work better for someone else.
