I guess 44 would be considered safe by the MFG. I know people on these boards have had there tires up to 50-60psi without much risk. You could probally get it up to +100 before the tire would blow (DONT DO THAT!!!).

I think 44psi should be alright. Any more than that and the tires might wear more on the centre of the tread. The general idea is not to have them too low that the tire becomes saggy and hard for the engine to do its work. I'm not sure if you would see much improvement with 54 as opposed to 44 (compared to say 34 and 44).

I just really dislike how Wal-Mart keeps making my psi 32 in each tire whenever I get an oil change. I need to remind myself to let them know to leave them alone.

I would run the tries at 50. My tires are rated at 45 and i run 50. I think there there is a slightly harher ride, but nothing major.

50 sounds like a nice round # to go for

I run 50, I think dan has run 60, and I've pymped a tire up past 120 before, but not driven on it, so yeah, 50 is good.

The are paving the last bumpy section of my test loop on Ocean Drive and when they finallly finish it I will run a few passes at normal and elevated pressures and see what the difference is. I can get pretty consistant results and should be able to see a difference right away, Be funny if it didn't make a difference . . . or better yet gets me even higher that I get already running 38psi.

I was really surprised that there is virtually no difference between the fuel efficiency of my Metro whether driven on smooth paved roads or grid/gravel roads. Perhaps the ground is nice and solid now that the temperatures are well below freezing.

Ocean Drive. Why does that sound familiar? Is that the street the infamous "Amittyville Horror" house is on?

That is very dangerous(120psi). You do not want to be standing near a tire when it decides to explode.
