I reduced the PSI per tire from 36 psi that the car came with to the placarded amount of 32. What would be the best pressure? My ride is better but will my milage suffer?

 

Is so it would be a tiny tiny amount. A few psi over what the book says is pretty common for most folks. By experimenting trying to find a sweet spot for handling & comfortI run +3psi over recommendedin front and rear.

Experiment and see.

 

The sticker in the door reads 32 PSI. That's what Honda recommends, so that's what I run. Others may feel differently.

 

I do 32 as the factory suggests, but on my Yokohama Avids they wore out much faster in the middle of the tread as if they were overinflated. If I get the Yokos again I will probably decrease to 29-30 and see if they wear better.

 

I run my tires at 35psi (inflated at approx. 25DegCel.). i find the ride more to my liking. as well i live in Ottawa, ON and the outside temperature in ottawa fluctuate by 10 degrees Cetigrade or more so during the day everything is ok when night comes it has cooled off so much that the tpms indicator comes on.

Also, i have 33,000Km on my tires and they are all wearing evenly.
