Be Aware! Tire Pressure..,

[amirh]

Hi all,
I just want to warn you guys about how stupid some of the dealers are( Isn't that obvious !). I bought my second civic (LX) 3 months ago, and I was getting a really rough ride. I could feel even the smallest bumps. The car was kind of jumpy in the highway. Yesterday, I checked my tires pressure and it was at 40 !!! I can't believe how stupid a dealer can be to set the tire pressure for a Civic to 40 psi!

I took the car to another dealer and they reset the pressure for me (I do not do it myself because I do not trust these 4$ gauges). He told me when they receive these cars from the factory the tire pressure is set at more than 40, and they have to reduce the pressure. That means that the dealer from which I bought the car did not do it. So, if you feel your car is not as smooth as it should be, remember that tire pressures can be high, even if you just picked up your car from dealer parking.

Good thing you checked, but just curious if you checked with the same gauge (that read 40) as you wouldn't trust to say 32?

My service dealer always fills me to 32 exactly after any time I bring my car in. It feels great driving away!

The problem is that I have two different Gauges. Before taking my car to the dealer, one of them read the pressure as 40 and the other one 35. So, I realized that I can't trust my gauges. I think now I now that my first gauge is accurate.

One more thing that I forgot to mention is that I live in Michigan, and weather is crazy cold. I bought the car in January which the coldest time(Average -10 F) of the year. If the pressure in winter was 40, I think in summer it would be around 43 - 44. This again shows HOW STUPID DEALERS ARE!

Was your LX brand new when you picked it up? Normally tire pressures are intentionally set very high for shipping/transporting vehicles. The dealer would then lower the pressure to the recommended pressue as part of their inspection checklist when accepting the car or at least before a buyer picks it up. Sounds like this was missed with your car. I personally tend to like a slightly higher tire pressure to add a bit of stiffness for cornering purposes. But I'm driving an Si too. Always a good idea to check your pressures fairly often anyway.

i drive with it around 35 daily, nitrogen filled tires FTW!

[bluetroll]

ya, i actually just checked my air pressure on the weekend.... it was at 35... it's supposed to be 32.

Mine was the same way when I took delivery at the dealer - 40psi!

[alexxtang]

i put 38psi for the front & 36psi for the rear for my R18 stock 16" tires. best for cornering... i had tired the tire pressure below 38 psi Front and -2 psi for rear. it gave too much oversteering. finaly, the 38 & 36 work out the best.

when you check your tire pressure, was it cold or running pressure?

40psi on running pressure = normal
32psi on running pressure = under inflated

be aware that you are adding up somewhere between 5-8psi to your tire pressure when they are warm and running. the correct way to set tire pressure is when its cold, try early in the morning.
i can go on and on but i'm sure u get the idea. if not then read this:

It is amazing how many dealerships don't appear to know/agree with this. I 've gone to a number of dealerships with various cars and they will come back and say that my tire pressure is high, that it is suppose to be at **psi.....yeah it is "high" in relation to the numbers on the little sticker in the door jam, I just drove 20 miles on the highway to get here.......
This is a pretty concrete thing, the whole cold pressure, running/warm pressure....

Yeah, 40 was the cold tire pressure, and as I said I live Michigan, so this means the tires were colder than what they supposed to be at the time of measurement!

im not going to read through all this but keep in mind that 32psi cold is close to 38-40 hot, 35psi cold is about 42 hot. and it only take about 1-2 miles to heat up a radial tire.

[iknowmysh1t]

honda ships there cars with 40psi. why? i have no idea!

[si_civic]

Remember to slightly reduce your psi on hot weather/pavement as heat from the road can increase the pressure from within the tire. :)
