+1, and the same goes for the harsh ride. I wouldn't use RFTs with lower than 45 series aspect ratio tires, as there's not enough rubber between the rim and the road to compensate for the increased sidewall stiffness. Even 45 series are marginal. With 50 series and higher you're hard pressed to tell the difference. As for damage, with 40 series and lower you'd best have pothole radar, no matter what the tire.
