My 1995.5 Isuzu Rodeo (2WD, 2.6 lts. Engine)corners well in the mountain roads where I live, but at manufacturer's recommended tire pressure (26 psi) it squeaks mostly and fishtails sometimes.
I found that inflating the tires ( Michelin P225/75R15) at 32 psi front and rear it takes the curves much better, with no lateral displacement and increased mileage per gallon (24 versus 21 mpg combined city/Hwy/mountain); I have done that for the last 8 years.
The tires wear as usual, a little more on the edges than the center, but that is normal in these roads.
I am taking a class in mature driving and read there the manufacturer's recommendation should be used.
Question:
What could be the set backs of the higher pressure?
Longer time for braking on wet roadways?
Risk of blowout?
Others?

Thanks for the help!

Often it is a case that the recommendations suggested by the manufacturer is just a guide and will not suit all conditions, often it is local knowledge that rules here, three are pros and cons regarding tyre pressures, high pressures harder ride, is the most common response, to soft it will float on the road, and as you have found higher is better for economy, I would run them at 30 front 32 rear and then adj for sever conditions as required.
