Always a bit of difference to be found between what the bike handbook says and maybe what an individual tyre manufacturer will say for the tyre on a standard weight bike!?
The pictures and text tend to be indicative of under inflation, and with possible inaccurate tyre gauge being used, inaccurate garage forecourt pumps, heavier than normal rider there are too many variables to stick rigidly to handbook, up it just a little. The slightly more wear on the right is usually because of roundabouts and underinflated tyres will exagerate that wear.
