Regarding loose nuts, i don't think anything is loose so it may well be the shocks. I'm a maintenance technician so i'm always listening for new rattles to fix!

Oh, and when it comes to getting flamed when overinflated tyres are mentioned, i got that t-shirt too! I was a member in an astronomy/space travel forum and there was a general science forum within it. There were guys in there that could calculate how much fuel would be required to send the ISS around the moon and back. So, i figured these fine people could shed some light on the subject of grip vs tyre pressure.

Well, i got one or two "maybe there's something in it alright" kind of posts and then it got ugly. Not once was there a calculation thrown about and after i was repeatedly told i would wear the centre more i had to post a picture of one of my tyres with 100,000km on it and EVEN wear, which was about 4mm at that point! A few mumbles and grumbles later and the thread died. I finished off by saying how disappointed i was to get such abuse from supposed scientists. I kind of expected not to get proper scientific analysis on the subject but i wanted to see it unfold anyway, just to reinforce my belief that there is a conspiracy in force, with respect to tyre pressure and grip etc.
As far as I am concerned the only time tires are wearing in the center is when ratio tire/rim does not match (oversized tire/narrow rim).

Unless a such mismatched combination, I have a very, very hard time to believe that a passenger tire can retain a convex (egg shape) form after applying a constant loading force of 4-500 kg.



I haven't seen that shape no even on an unloaded tire inflated at 50 PSI.
All the images showing a convex form of a tire are drawings such as this



But even in this image, the presenter fails to show me the egg shape form.

That does mean I might not be wrong. If there is any tire specialist that can show me images of an egg shape passenger tire, I'll be more than happy to apologize.
