I have Nitto 555r's and 555's . It says Max tire pressure is 44 psi.

What would be an ideal tire pressure for these tires so that they will last the longest??

Thanks.

 

look at what it says on the door of the car, however, it is better to be a few pounds over then a few pounds under.

 

The pressure recommended by the manufacturer is to help maintain the contact patch of the tire on the ground. I use 33-34 front and 29-30 rear. I find these pressures help to reduce understeer a bit.

 

thanks for the replies. I cant use the tire pressure that is says on the door, They are totally different tires. Does anybody have these tires and know whats best?

 

id go with the tire pressure that it says on the tires...that is how you get the best mileage out of the tire at least, if you want more grip, go with less pressure, i would NOT go over the MAX pressure.....that isnt a good idea AT ALL

 

i forget what the door jam says, but i try to run 30psi at all four corners even tho my left rear is leaking alot on my winter tires.
