I have 195/60R15 Bridgestone Potenza tires on my 2003 Celica GT. I don't there is a recommended tire pressure listed on the tire. There is a maximum psi, which 44psi, on the tire. What tire pressure would you recommend?
Those are the stock tires which Toyota uses on most all base model Celica GT - Open your owner's manual -- or better yet, for most vehicles, check the sticker on your driver's side doorjam body -- and it will tell you exactly the recommended tire pressure.
