Difference between tubeless vs tube tires is huge... also available front tires (and their profiles) can be a big difference - as an example, I ran a Anakee2 100-90/19 H rated (bias ply?) and hit the side wear bars in 2.5k. Replaced with an Anakee2 110-80/19 Z rated (radial) and I'm now at 4k with barely noticeable wear. Not to mention that the sidewall tread on the narrower tire was much more limited. However if you're a real scratcher, the non-XC has pretty crappy ground clearance.... seriously, it's worse than my previous Harley (XR).
