I'm left handed but feel comfortable on either left or right turns.
You should wear out the right side of the tyre first because of the camber of the road

Uh-oh. That old furphy again. It's been demonstrated the camber is far too small an angle to cause asymmetric wear. You can search it in this Forum.
I believe that the right side of a rear tyre can wear out faster because, around town, we tend to take right-hand corners faster and under greater acceleration. Most left turns (say, at a T intersection) are tighter than right turns so we use less power and because we are slower, we tend to lean less. Turning right at the same T intersection would involve more power and a greater lean angle and this will produce more wear on the tyres, particularly the rear. For those whose riding is mostly open road stuff, this wouldn't be a problem.
This same logic can be applied to round-abouts - the larger radius of the r'about itself, compared with the radius of the left turn, encourages us to dial in more power, which results in more wear (and fun!).
I have seen many tyres that have worn more on the right and I am convinced this is a contributing cause. I would suspect that in countries where they drive on the "wrong" side of the road, the left side would wear more.
Just my thoughts.... I'm sure this has been covered many times.
