My tire's max pressure is 51 psi however there's a thing on the tire that says "Never inflate beyond 40 psi on seat bead". What does this mean?
Edit: Thanks everyone, TIL I know nothing about tires. Max PSI does not equal better performance. Now if you'll excuse me I'm going to go and reflect on how I knew so much about cars but knew nothing about tires.

It means when you are first mounting the tires, do not exceed 40PSI while you are trying to seat the bead of the tire against the rim.
edit: Since your tires are apparently mounted to your wheels already it means nothing :)

Ok cool so does that mean that I can inflate them to 50 psi?

Uh, I suppose so. But why?

Because I was inflating them to 40

if it says they will take 50+, go for it. Is it a vanagon? that was the last thing I remember that took a pressure that high

You shouldn't inflate your tires to maximum PSI unless there's a reason for it. On your driver's side door jamb you should see a yellow or white sticker that lists the tire pressures (front and rear) for your car. If it's not there it is in the owner's manual or you can look it up online. I'm assuming you have a car, in which case it might be anywhere from 30PSI up to 40PSI, or if you have a truck it could be higher.

This is on your bike, I'm assuming?

You could, but that'd ruin your ride/handling and make your tires wear faster :P recommended tire pressure should be on a sticker somewhere, usually the driver's side door sill (although I've come across several cars with it inside the gas cap). If your tires aren't factory, the "ideal" pressure might be slightly different by a few PSI, but the recommended should still be fine.

To add to what party-vi said, don't over inflate your tires unless you know what you are doing:
1. dangerous
2. any mileage gains are offset by faster and uneven tire wear.
I have tires that go to 80, but Im never going to see that, 45 tops and im running 35 now.

What Party-vi said.
Inflating to max PSI will actually cause the tire to balloon giving it a smaller contact patch with the road and reducing traction while also causing uneven tread wear.

Don't do maximum because temperatures (both ambient and operating...ie tire heat) and altitude can increase your relative tire pressure.
51 sounds awfully high, even 40 is up there. I'm used to seeing low-ish 30's.

The key thing is that "Maximum" is not "Desired."
You CAN inflate them that much without them exploding, but that's not the PSI at which they are designed to run. Your driver-side doorframe should tell you the manufacturer recommended PSI.

There should be a sticker inside the driver's door jamb that shows you recommended inflation pressures, like this.

One thing to remember. Door sticker inflation is mostly geared toward ride comfort. Generally, an additional 3-4 psi yields the best wear and gas mileage.
