Not if it's the specified size.
If someone out there's making a tire in the correct size that is somehow significantly different than usual, you should count on them to provide a pressure specification. This is highly unlikely of course.
These tires fit multiple bikes. My FJR took the same size.
What about standard and reinforced tires? What about with passenger and baggage and without?
If you call and talk to a tech I can tell you from past experience they will recommend a good tire pressure.
As far as MAX PSI yes you can run MAX PSI without any problems. That is the MAX PSI calculated for the tire to hold traction within its traction rating, load rating, and wear rating. Your tire will not explode if you are at MAX PSI they are capable of running much higher pressure and keeping the tire inflated. I do not recommend MAX PSI but if for some reason you had to run at it, it will be fine.
This is very subjective and tire specific due to compounds and tread patterns. Also ride preference. I do not like a soft tire or suspension as I do not feel as connected with the road surface. However I have been caught in snow and lowered pressure to get more contact patch on the snow/road And road type and temp will affect wear. Here on the Right Coast I may get 10 K out of a tire we have pretty decent roads, mostly blacktop and concrete. Get down south like WV you have tar and chip and everything else in between. Old dried tar and chip is tearing tires up as every chip embedded in that old tar is hacking at your tires.
If you follow you bikes recommendations you are in a safe area. However is that the best for tire life, grip, and comfort for a particular tire/bike combo you do not know. It is a starting point or reference at best.
Again 40/42 has given the best results over more tires for more people in more areas by the posts on this forum and many others. Like I said to throw that data away is not too smart. And if you really want to know for sure get a tech on the line from your tire manufacturer and let him tell you what their recommended PSI is.
Temp/PSI rise is a good indication you are running in correct PSI. Unfortunately there is not a TPS on our bikes capable of giving us that information. The last I knew that gave Temp and PSI was Smart Tire aftermarket I think. There is a % of temp and PSI range that is considered just right for tires but you need the TPS to see it.
And this is a oil thread in disguise for sure
