Finally got my 'Grapplers!!! At first I tried pumping them all the way up to 45 because I like a real firm cornering posture and steering/accellerator response but it was just too hard with Detroit's pothole situation. I lowered them to 36lbs and I like the ride a LOT better and the cornering still seems great. One other benefit I notice having them softer is the straight line stability is MUCH better than with them (or my old Yokos) rock hard. When the road surface would get weird here as it often does, I used to uncontrolably bob and weave a lot, but now it plows right thru everything like a normal car. I love these tires!
