I am fairly new to SXS. Picked up my camo 700-4 last week. I was reading about tires and thinking if 8 ply tires are more puncture resistant and better load rating that it would be a no brainer to put on the SXS. What are the downsides vs. installing 6 ply ? I do not intend to do severe off roading, just trail riding (beginners and intermediate).
