Traction is also a relative point depending on conditions. If you are running higher tire pressure you may experience slightly less traction but it is not likely to be a very significant difference unless the tire pressure is massively higher. I believe the Mazda 3 ( a lighter car) uses the same tires as this car but recommends a tire pressure of 36 or 38 on the door sill (had to adjust a friends tire pressures recently).
but the suspension isn't the same, same tires, completely different cars.

i typically run tires at higher pressures than what is recommended, even 3psi over will greatly reduce the innermost treadlife. the last 2 set of tires I have had on my buick i ran at 38/36 when recommended is 32/30. the innermost tread was to the wearbars when the outer 2/3 still had 5/32" remaining. it makes a difference.

like i have stated before, i have tested higher pressures and on the stock yokos i don't see any reason to run over 35psi, the tires just can't handle it and i got signficantly less traction. i didn't notice much difference in steering feel, but the speed at which the tires breaks loose is lower with more pressure
