Clutch vs Tire Size (Hunterworks Opinion?)

With all the questions of "which size tires should/can I run run on my rig" I was wondering what Todd’s experience at Hunterworks has been with regard to tire size induced clutch issues on 570/800/900/1000 etc?

So Todd, in your experience what sizes larger than stock on which models begin to create issues where the clutch should be addressed? I know some people treat their rides differently, but there has to be a tire-sized induced problem in general. Diameter, width, weight?

Thanks,
