The car is a 2007 honda accord, the recommended / stock tires are 205/60R16's. 32 psi in the front , and 30psi in the back .
I have just put on a set of 17 " mags , and the tires are 225/45zr17. Do i still follow the 32 psi on the front , and 30 psi in the back due to the fact that the tires are different size ?

thank you .
 
Go with what's recommended by the vehicle manufacturer, it will be the same even after you alter the setup.

225/50/17 would be closer to original circumference

^^ this is how people wear their tires out much faster than normal and put everyone on the road including themselves in danger.

Keep your cars tire pressures the same, no matter what size.

T'es tu fou dans tête? C'est les specs de l'auto qui prime pas le psi du tire. Some high performance tire can handle well over 50psi that does not mean the tire should be inflated at 50 on an accord.... Chaque vehicle a des specs particuliers prenant en considération les composantes d'amortissement et de suspension. For an accord anything from 30 to 35 is ok

actually you should add or remove depending on the load rating of the tire. Say for example de original load rating is 91V and the new tire is 94W. Then there is a 3 load rating difference.

That being said, I forget the formula (lol) but it was add or substract a certain amount of psi per load rating.
 
The # on te tire is te max psi it can handle and remember that if u put like 38 psi in cold it can get to 45+ psi when weather gets hot.

If you go to the Toyo Tire Guide

http://tirefinder.toyotires.com/

and look up your vehicle and tire size (+0, +1, +2 etc.), they will give you the new pressures to accept the same load as your original size. Usually when putting plus sizes on a car, you must increase the pressures a small amount to maintain the same wear patterns and load ability.

Just put the same psi that the car recommends but maybe add a little bit more. You don't want lower profile tires to be under inflated you could possibly damage the rim or something.
