I hope they do improve for you. If not you will be cussing them for a long time because they wear like iron. As for tar snakes. Every tire on every bike I have ever ridden has been uncomfortable when I encounter tar snakes. When I see tar snakes I tell myself to stay loose and go with it but I always experience that "Ah Crap" moment. If you find a set of tires that feel stable in tar snakes sign me up for a set.
I totally agree with F6Bster, this is my second set of the elite4’s. The first set I got 19k on them I checked the tire pressure every ride 40 front 42 rear. On this set has the same characteristics that F6Bster is talking about 35/40mph wobble, last set never did that. Yes I have the fork brace. Next tires for me will be the Stones.
