They tilt back to help absord the "impact" of the landing, the bogies are held in that position so that they absorb some of the force of the landing making it smoother.
However if they cant fit them into the wheel wells in that position then they will tilt them the other way, such as in the case of the 767, which is why it is a lot harder to grease a landing in a 767!

I suspect that the primary reason is to save space as tilted bogies take up less room.
However I believe that tilted bogies allow a gradual 'spin-up' of the wheels and this saves on tyre degradation and also stress forces on the undercarriage on touchdown.
Correct me if i'm wrong

On my aircraft, the bogies are tilted nose up for landing. The action of landing and tilting the bogie compresses a piston called the 'hop damper', which has the sole purpose of damping out the landing, thus saving G&Ts/Martinis. On gear retraction, another jack tilts the bogie nose down so it fits in the well.
This aircraft however, was built in the days when the British Aircraft industry built proper airliners, and money was no object!
Which aircraft am I talking about?

For the A330/A340 the MLG holds a 14 deg nose up tilt. This allows most of the landing shock loads to be absorbed by the time the front truck wheels rotate to contact. During gear retraction a mechanical "shortening mechanism" operates to shorten the MLG shock strut and, at the same time, rotate the bogie to a perpendicular position so that it can fit into the hole.
