Tire Pressure and Spring Tension Strategy

Does my tire pressure Vs Spring tension tuning strategy make sense?
First I plan to find the best inflation pressure for my tires by checking the contact patch. I’ll do this by riding from dirt onto pavement and looking at the dirt tracks on the pavement. I think there should be an even distribution of dirt across the contact patch and I expect this to occur at somewhere between 2psi and 5 psi. (This is with new 8 ply Kenda Bearclaw HTR tires.) I am hoping a fairly low pressure will work because this will provide better traction and a smoother ride. If the ATV is too hard to steer at the low pressure I will increase the pressure until it turns easily enough.

After I tune the tire pressure, I plan to adjust the springs to be as tight as possible for good cornering while still being loose enough for a comfortable ride over lumpy, bumpy, rocky trails. Is this a good way to tune tire pressure and spring tension?

My ATV is a 2010 Renegade 500.

Thanks.
