Hi ukflyer,
You have some good advice. Tires usually come with the mold release agent not all the way cleaned off. I do a progressive natural cleaning on tires(tyres) keeping them up to optimum temps and scuffing them progressively to the edges. About 100 miles US should do it.
As far as the engine thing. I really never said to baby it. They do need throttle action and varying rpm. Hills or inclines are a good thing. Again, no lugging or detonation but a good pull after 100-200 miles. This helps with the top end. You'll give her something to chew on and think about but not too harsh

. Getting a bit higher BMEP Brake Mean Effective Pressure in the combustion chamber to keep things cleaned out and this also provides added pressure that pushes the rings into the cylinder wall, sealing the rings to the cylinder wall.
Make her work but give her a breather once in awhile too. This may sound sappy but treat her like a good horse. They know when they are cold and cranky or warm and feeling good. Use the force and listen to her.
Again rings aren't that much of a deal anymore but stabilizing and putting a final polish on things.
