Parking here is extremely tight. Hence softroading is common if not mandatory :-[ I got onto a packed dirt embankment lately and it looked like the rear right was nearly off the ground (A4 with sport suspenders has extremely beefy front and rear sway bars and i think that was a contributing factor to my one-wheel-in-the-air scenario).
The Michelin X-Ice 2 are 195 65R15 and the front right tire was severely squished, as if it had 10psi (it actually is inflated to 32). It seems that two diagonally opposed tires (FR & RL) were severely overloaded while FL was carrying maybe 1/8th of the car weight. XI2 survived somehow with about 3800lbs worth of a car essentially resting on 2.5 tires; thusly I wonder to what extent the passenger tires are overbuilt.
Me thinks if I have 91 load rating that's 1356lbs and 3800/2.5 is
1520lbs. If one manages to get two tires in the air that's 1900lbs per tire - waaaay over the 1356lbs rating. A blowout is sure to follow or not?Now suppose I deflate to 25lbs before venturing into soft sands, load capacity should drop lower yet, right?
thanks
