Tire Pressure question

I don't understand how hard it is to get a solid number for tire PSI. I have Metzeler ME 888s, so I read the sidewall. All I can find there is something printed about max load and max pressure. But it doesn't say what to inflate the tire to. Metzeler website says to refer to owners manual. Owner's manual has numbers but it's for Metzeler 880s, which are not the same as Metzeler 888s. For 880s it says 41 rear and 36 front. But I gather from the interweb it's common knowledge that you run 888s at lower pressures than 880s.

So if anyone running ME888s has something solid about front and rear pressures, I'd be very grateful to hear it.

Internet on metzelers site says do what your bike states.

Bottom line it does not matter as long as A: you do not exceed that max pressure and B: run about the standard for your bike. Tire brand or model does not change things unless you get into supper sport stuff. On these bikes you want a slightly higher on front to prevent the typical cupping. 33 to 36 up front. 44 I'm the rear unless 2 up then run 46 to 50 depending on how big the rider/ riders are. When I go 2 up with the wife I go 48 in the rear and give the shocks an extra tick

Why so generic.... Because of you get more than 6k miles you have achieved greatness so unless you ride like me (10k per set of tires.... It will never matter unless you are on a track and even then I just do a little back road stuff. I rarely wear a tire out unless all the rubber is gone other than my tiny chicken stripes
