Very true and good points. I am a little surprised how soft my 26 big horn sidewalls are on the 14's. My terracrosses running 4lbs on 12's were much stifferYup, different strokes for different folks...in my area pinching a sidewall is not a concern at all as we don't have rocks. I need the quad to turn when I hit a corner, not wallow over on a soft sidewall then start turning...my trails are 50" max and the trees are pretty close so any delay from when I turn the bars to when my quad actually starts to turn is not good. As for air pressure I run 6-7psi in my HTRs and they handle like a dream, but the sidewalls are really stiff on the HTRs so that probably helps a bit also.On green and blue trails we r flying, on blacks and double blacks a lot of it is much slower and technical and 99% of the time rocky. We don't ride fire roads or pavement unless we have to in order to get to next trail head. As such, we have had at least 3 times more pinch flats with 14's vs 12's. Flatted tires include roctanes and og bighorns (so pretty durable tires). 14's have to be aired up 8-10lbs, 12's I ran 4-5. This is over the course of about 2000 miles in West Virginia....for those trails, 14's suck
Bp - I wasn't aware of that rule of thumb. Good to know!
