PSI Tire Pressure

[Jewls]

Ok, this might be in the wrong forum, but you all know I have only had my 04 for about 2 weeks, actually 2 weeks today. It has had a very bumpy ride since I got it, and finally got fed up and decided it wasn't just me or the road conditions. I checked my tire pressure to get the obvious things out of the way. According to Toyota, proper tire pressure is 32 PSI all the way around. Well, I only have ONE tire that is less than 40!!!!!!! And that one is 38, still high. So I have basically been riding around on wagon wheels for 2 weeks. I am taking it to them today to adjust it and to inspect the tires to make sure they are not ruined by uneven wear. You would think they'd check this stuff before delivering me the darn car. What PSI does everyone run on thiers just out of curiosity?

tires differ from all others.

best way to check is to look at the tire specifications.

32psi may not be the ideal psi.

some tires have a max psi of 51. (not saying that yours will be 51max psi though)

When I had my factory 17s, I had them set at 32psi. Since, I just got new wheels and tires, I haven't had a chance to check. But that sounds like bad. Have you had any luck contacting your local Toyota dealers about this and what actions are they taking to prevent this from reoccuring?

The proper PSI for that specific kind of tire should be written on the sidewall of the tire.

Overinflation can cause less traction on the road due to the tread "bubbling" and having less contact. Underinflation is a much bigger problem, but overinflation is bad too.

You should check PSI when its cool and not when you just rode on them. When they heat up or sit in the sun, the air pressure should increase, and thats normal. The number thats recommended on the sidewall is the recommended "cold" pressure, like in the morning when you wake up after its been sitting there for 8+ hours out of the sun. It may rise substantially if it sits in the sun, or if you just drove on them.

if you check it out in the morning, and it still very overinflated, then get it fixed.

I actually did check them this morning while it was still fairly cool outside, around 68 degrees, and those are the numbers I got. The fact that they are overinflated is one thing, but the fact that they are all different is what had me most concerned. I plan to talk to the sales manager today to let him know they need to be more careful about this. I used to work at this same dealership, so I know everyone there, hopefully something will be done about it. Hopefully it did not mess up the tires, or you better believe they will be buying me new ones!

Don't inflate your tires to the pressure molded on the tire. This is the maximum pressure the tire can stand. Inflate to the pressure on the door sill of the driver's door.

32 psi is right on the money.
