My low mileage '04 has only 70k miles, but I've run tires on it every mile of the way. Every tire I have had on it has gone from new to worn out except the one that took a broken beer bottle to the center of the tread. At no point has any tire failed not to wear out at the end of its life. Since I ride 2 up most of the time I tend to run 44 psi back and 42 psi front. If I don't diligently drain my compressor's tank and run an air drier in line with the output my tire pressure goes up as soon as the tire starts to heat up, then I run higher tire pressures. Also, if you are going to fill your tires, be sure they inflate too.
It always amazes me when I take off a completely misshapen and bald tire and replace it with a new properly shaped tire with good tread that my FJR handles better. I'm sure the two events must be related in some way. What is even more odd, it doesn't matter who made the new tire, the handling always get better anyway. In short, I do highly recommend tires, your FJR will always handle better with them.
