I put 1350 miles on while at Bike Week this year on the Commander 3 front. I have a Commander 2 on the rear with 13,500 miles on it now. It was a great week of weather and rode in no rain. Couldn't tell any difference in the Commander 2 on the front that was taken off.
The tread pattern is different between a 2 and a 3.
Again, the main reason I replaced the front tire was that it was off to remove the Legend axeo cartridges and readjust to a softer setting and am happy I did that. I also put in new fork bushings and seals.
Also, I put Ride-On in the front tire and no weights and it was smooth up to 80 mph.. Happy with that thus far.
One thing I can tell the difference in moving the bike around in my garage is that the Commander 2 squeaked when backing up and turning and the 3 does not.
I run 38 in the front and 42-44 in the rear.
I am Michelin biased as it is my tire of choice for cars and trucks. Hope this helps.
