Tire Pressure??? How much air for 20's"
 

I have a set of 20" falken tires.
Falken FK 452 Tires (245 - 35 - 20)


on the tire, it says a max of 50psi and the store owner where i bought the rims and tires from says to keep the pressure between 38-40.

While the nissan dealership tells me 36..

what psi should i be putting?????

Stock pressure or a little bit more is fine.

since its 20"s i put mine around 45

When the tires are cold, go with 36-40psi if you want a smoother, less bumpy ride.

Go with 40-44psi if you want slightly better gas mileage, but willing to have a slightly bumpier ride.

i use 40 in my 19s... and what the wizard said is right basically.
