Tire psi

Skulls06 · 03-31-2020, 11:17 AM

Hi all,

Summer here is canada. I have changed my tires to a summer. Find below my config:

I put 36 psi front & 44 psi rear. Is it the correct tires pressure ?

Potenza RG-050A RSC
Front tire
245/35/20 95Y

Rear
275/30/20 97Y

Thanks & stay safe.

Seems kind of high. I run 35/39? I drive 99% of the time alone.

The OP may wish to view the info in the driver's door jamb.

I dont see the tire pressure for my tire size.

it's in the manual. I believe the pressures reflect 4 people in the car and luggage though? Don't recall..

I like 35 front 39 rear on my 18 inch summer and 19 inch winter. 90% of the time I am driving solo.

No. It's a cold tire pressure. Dont count how many people is in the car.

Yeah I am talking about cold pressure. But aren't those PSI ideal assuming you have a full loaded car?

I dont think so. 36 & 44 when no one inside the car. It's will be difficult if we count how many people.

@ the garage, i dont think the mechanics will check how many people you will put in the car. They just put the psi as indicated @ the door sticker.
