I ran my Avons with 19 psi unknowingly as my air gauge was wrong. It resulted in the outside wearing fast while the middle looked almost new. Have since found two accurate gauges, one digital and the other analog. The tires were replaced at around 8,000 miles with Blockleys along with the 'comfort steer' kit.
Bump steer is gone and I'm running the front end at 24 psi with great improvement.
