A few weeks after I picked my car up I checked the tires to see if the pressure was low. I was surprised to find the dealer had inflated my tires to 36psi front and back. Four months later the pressure is down to 35psi now. What tire pressure do you use for your Turanzas? Do you think over-inflating them a little makes the ride a little less harsh?

 

I set my tires to 35-36 psi front and back, and like the way it rides.

 

The tire pressure specifications are different for 5AT and 6MT. There is a sticker on the driver's door jamb with recommended pressures.

I have a 5AT, and have played with various pressures, and finally settled on 33psi all around. The manual and the sticker calls for 32psi for 5AT, but anything between 32 and 36 is ok; it is strictly a matter of preference.

Some people like the better handling a higher pressure gives them, while others like the comfort of a lower setting.

Also, as the temperature rises in the summer, so will the tire pressure, so act accordingly.

 

IMO, you could use 32/32, 35/32, 35/35, or 38/35. I don't remember what the owner manual says... Maybe 32/32 for 5AT.

I used 38/35 for my EL42s in the past, this could help the performance and get better MPG, but the wear of tires could be faster...

Personally, I prefer to have the higher front tire pressure than the rear's. This could help enhance the handling and reduce the understeering to FWD vehicle.






Oh... Ron_A had posted... I forgot to refresh my screen before posting...

 

The manual recommends 39 front and 35 rear for "high speed" driving.

I run 39 front and 36 rear as I prefer a 3 psi difference on fwd cars. I don't think the ride is harsh, and prefer the improved handling. Of course it will be nice to replace the EL42's when they are worn a bit more.

why did you move my wheel & tire question to tire section and I never got a response by the way, because noone reads them, and this you left and even answered to this one?

 

32 psi for the 5AT the manual says

 

Yep, that's why I was surprised the dealer inflated to 36psi.

 

My bad... the movement doesn't take place right away due to the slowness of dial-up connection... it's hard to use Interent in this countryside town... my cell phone only provides 9Kbps...

All tires' thread should stay where it should be, "sub-forum". However, if the topic is important for everyone, it will stay in Main forum for a period of time before moved over.

But not this one...


About your thread, http://www.acura-tl.com/forums/showthread.php?t=86526, there have been 67 visits so far. I'm waiting for the answer, too... Anyone knows?

 

I guess I need to re-read my manual, I didn't see the "for high speed driving" adjustments.. I might try that as I'm often a speedy freak on the I75/I85 connector.

 

Y0u would need to inflate above the 32 psi for sustained speeds in excess of 100 mph. Or perhaps for a heavily loaded car.

The mfr's spend a lot of time determining the right pressure. It has to do with contact area, rolling resistance, and shock resistance. An overinflated tire is far more likely to sufffer damage, often hidden, of the tire body from potholes, curbs, etc. It will also wear in the center more, and the handling can get tricky, as the car is "dancing" on tiptoes. Roadholding can actually decline - it is primarily the turn-in, which is sharper, that people feel with higher pressures, and to them that equates to better handling. If the mfr's thought that 33 was good, they would go for it, as it helps mileage a bit, or 34 or 35.

But they do not.

For high speed driving, yes, you need to inflate, since the heat generated by tire flex can cause the tire to weaken and fail (the Explorer Syndrome). But few of us routinely drive at 100 mph, extended intervals.

I say stick with 32 psi.
