I run my van tyres at around 80psi even though the max reccomended on the tyre wall is only 65psi. I do this purely to get even tread wear as any lower and the shoulders wear far faster than the tread centre even with motorway journeys (minimal dry steering wear). A knowledgable friend of mine and MOT tester says that although he doesn't condone this, Tyres do have an inbuilt pressure safety margin of something like 100%. I have done this for around half a million miles and have had no problems with tyre failiures.
To counteract the loss of traction and enable me to make the effort and really push my tyres into the road I have gained approximatly 2 stone as I reached my 30's.
