Those are the standard inflation pressures for Saturn S-series cars. You will get better handling and fuel economy at somewhat higher pressures at the expense of a bumpier ride. Don't go all the way to 44 psi though, that is too high. I think optimum cornering grip occurs somewhere in the mid-30s.

That is the right pressure. More pressure will cause your wheels to lock up more easily when you hit the brakes in emergency, especially if you do not have ABS. Also, if you have bigger tires with higher load capacity ( in case you put 205 size ), you can get away with even less air pressure than the manual says, not that you have to.

Default Re: tire pressure?

I have always run my SC2 (and prior to that my SL2) at 30 front, 26 rear as indicated on the sticker. The car handles great and I have exceeded 40MPG on the highway, so it isn't hurting my gas mileage any.

Running them higher might give you better mileage, but it will reduce the contact patch between the tire and the road, which won't increase your handling, not to mention the fact that your tires will wear faster in the center than the sides. Less tire touching the road means less traction.

as long as they have a load index of 87 or more then use 30 psi front and 26 psi rear. if the load index is less than 87 then you need to put more air in them. also if you are autocrossing on them you would need more air for sure.

Default Re: tire pressure?

is that the standard tire pressures for all saturns ? I never really checked cause after (a long time ago) I had my tires installed from a shop they said to keep it at 35psi all around, if its supposed to be 30 front, 26 rear that what I should put mine at. My car slides around VERY easily in the rain, maybe this will remedy it

I think all S-series were designated 30f/26r, but I could be wrong. There should be a sticker either in the trunk or inside the driver side door.

Depends on the tire. High performance anything holds best, lasts longest, and feels "tightest" at around 39-40, if max is 44psi. My Falken's max was 52psi, and I kept them at 51. Ran NICE. Of course, I like to feel any tiny pebble I drive over. Some don't.

that's the standard tire pressure for S-Series Saturns. Look at the sticker on the door. forget what the shop told you unless they have "Saturn of" on the front of the building 35 psi in an S-Series makes for a stiffer bumpier ride. it will probably slide more in the rain now...
