PHP Warning: Use of undefined constant VBA_SCRIPT - assumed 'VBA_SCRIPT' (this will throw an Error in a future version of PHP) in ..../includes/functions_navigation.php(802) : eval()'d code on line 1 PSI in tyres - Page 2
Can't see any -ve to keeping the pressure as high as possible but there are plenty of -ve's if you go low. I've blown a few tyres and the dealer puts this down to storing the boat in a tropical shed which is always over 35C. He reckons I should only get 2-3 years out of a tyre in these conditions. When I leave shoes in the shed the soles peel off after a few months.
Most light truck tyres are rated to 60 or 65psi and generally speaking are best run at those pressure.
These are 8 ply tyres and are engineered to cope with the higher pressure which enables the higher load bearing capacity.
Run them at lower pressures and you are actually unduly loading the sidewalls instead of the tread area and you will reduce the tyres lifespan.
Many years ago I managed the workshop of a major tyre retailers store in Oakleigh, Melbourne and 8 ply tyres were always run at or very close to their maximum rated psi as technical discussion with the manufacturers suggested that max pressure in an 8 ply would ensure longevity.
