i have to agree with bhazard, i have worked in two different tire shops and have seen many issues with tire wear and failure do to wrong inflation, what people dont realize though is that there are more factors than just pressure, vehicle weight, driving style etc. all play very large rolls when it comes to how a tire wears. I am not saying that anyone here is wrong, but i will say that you have to be careful about over inflating tires (beyond vehicle manufacturer specs, tire manufacturer specs are often much higher than this) and be careful when telling people to inflate there tires to max sidewall pressure and beyond. if i still worked for a tire shop i would be more than happy to start documenting this kind of stuff but then again im not there anymore, oh well... next time i work at one (probably this summer) i will start documenting tire inflation related issues. again, im not saying anyone is wrong though because there is more than just tire pressure acting on the tire.
