Rear wheel alignment.

I have a 2016 RT Ltd to which I have just fitted a new rear tyre. I have since ridden it about 200m and the belt tracking is within limits, less than 2mm from the flange. What I have noticed is that the bottom of the rear mudguard which comes to a sort of point is not in line with the centre of the tyre but off to the right. I used a straight edge along the swing arm, where the axle comes through, back behind the tyre and measured to the centre of the tyre on both sides. Looking from the rear there is a 30mm offset to the left. I have had the bike from new and It has not been in an accident so does anyone have an idea if this offset is correct or is something out of line.
Thanks

Did you Jack it up and spin the tire to make sure the belt was tracking correct with the spline on the wheel. I had to get a new belt installed on our 2011Rt. The shop guy said he had a special tool to gauge the wheel. Not to sure how he did it But it runs true
