Clearance will be adequate, until it is not. :hat:
I'm on borrowed time as I have not installed a sump guard.
I run 16-18 psi on 205 50 15 Kumho Victoracers. I run 20psi on soft sidewall 195 50 15 street rubber.
In my experience the R comps will pick up and toss more stones due to the wider tread, the stickier compound.
I added "mud flaps" to the front fenders but still get stones thrown up into the cockpit.
I also have to clean out the lower frame rail/body joins of stones.
