On an 04 the recommended PSI is 32 all around, I presume they mean 32 cold. Which makes me wonder, once the tires get warmed up then you'll be running on about 34 (this is for daily driving). Is this correct?

I ask because I've been keeping my tires at 30 cold, once they warm up they are around 32, but this week I bumped them up to 32 and found the car to skip all over the place...is it me or can you really tell the difference 2 psi makes?

Thanks.

 

I run 32 front and rear and I don't "skip all over the place"....

Depending how you drive, 2lbs could probably make a difference.

 

Are your tires still cold when you're skipping all over the place? You've gotta let them warm up before you go nuts. Actually, you should never go nuts in public.

 

I check mine cold, which where I live in the a.m. is around 50 degrees. I can tell when mine are off a pound or two, both in ride, handling, and alignment. On really hot days, it rides a bit stiffer but nothing horrible. In the peak of summer, when mornings are in the 70's, I reset to 32 at that temp.

Are you sure your spring spacers have been removed? Also, have you checked with another tire pressure gauge? Maybe yours reads low.

 

You should set the pressure cold at the recommended air pressures for the car. I don't see anyway possible you can tell two psi on a street car.

 

After driving it at 30 cold for about 8k and bumping it up 2psi to 32 cold I have noticed that it bounces over bumps more to be more descriptive.

Does anyone know what kind of handling differences one might expect from adding extra psi? For instance, a turn I take everyday going to work got a little scary this AM when the back end kicked out a bit (before someone nannies me, it's an exit ramp and I wasn't going balls out like a 16 y/o with his two friends in the passenger seat ).

 

i have a 2004, and i run a strict 32 lbs cold, if the pressure drops 2 lbs i can feel it so i check the tires often to measure what is the best lbs to use...i have tried 35 and don't like it...my car seem very sensative to lb changes in pressure , on my other cars i ususally run a couple of lbs more to give a firmer ride...but not the S.

i have 15,500 miles on my car and the rears which wear faster are still looking ok...perhaps i will go to 20,000 we shall see...i have not had the car alligned and all tires seem to wear evenly...go figure, i guess i just got a good car in proper allignment.

when cold the car rides stiffer and bouncier and it takes a few minutes and a few miles to warm up and ride smoother, it is a subtle difference...and when it is cold out, say 40-50 degrees it also rides harsher, this is to be expected with the type of car and tire setup we have.

i am contemplating replacements iwthin the next year and so far the yoko es 100 looks good, i have them on my volvo T5 and they were well and the car handles well. anyone have any experience with this tire as a replacement on your S????
