IF you have the correct CT it speaks for itself..... Example, a Bridgestone DriveGuard Run Flat is designed to give an automobile (think of the weight) to be able to drive 50 miles at 50 mph on ZERO pressure. That would be excessive pressure on any sidewall. I have 28,000 miles on my Driveguard, Interstate, Mountains, Dragon 10 times, 98* temps on the road in FL and several winter trips to WV waiting on outside temps to get to 50* for the 1000 mile trip home. After getting used to the feel of the tire, 28--30 lbs has proven best for me. BT45 on the front with 16k on the tire at 41 lbs still looks close to new. The rear tire DOES Not ride on the sidewall, it conforms to the ride curvature and always has at least as much rubber on the ground as a Moto tire. Never had a slip in dry or wet and lots of rain in FL. This is one of the top rated tires for traction on cars for wet traction with soft rubber on both outer edges and a silica band in the middle for mileage. The torque on the F6B will still scorch these tires if wanted for a short distance. The only drawback I know is in a parking lot going 0--5 mph it is a little harder to maneuver.
