i have put type s rims with 225/45/17 tires, will someone tell me if the 36 psi that i try to maintain as constant tire pressure too much or too little...

thanks

 

1)What type of tires are they? 2) Maximum pressure listed on sidewall? and 3) Load rating of tire (i.e. - 94V...)?

 

I believe the max you should put in is 30/32 p.s.i

 

I'd stay in the 31 to 34 range, I use 34 frt and 32 rear as there is more weight on the front tires.

 

36 psi is a lil too much, dun u think??
i'm on 34 front 32 rear.

 

LOL

He's not running stock tires. You don't know what they are or the construction so how can you guys recommend a tire pressure. All you know is tire size. and that it's a TL. There's not enough info to respond.

 

sorry about the lack of information when I posted the question...
I have aftermarket tires on, Nitto NT450 225/45/ZR17 and I try to keep 36 psi...

 

36psi is in the ballpark.

For the TL's stock tires, 32psi is recommended for the 91V rated tires. Stock tires are max rated at 1356lbs @ 44psi.

The Nitto 450's are rated at a max of 1477lbs @ 50psi.

Depending on your driving style, 34-36psi is within reason in my opinion. Just watch your treadwear patterns. If the centers look like they're wearing faster, lower the pressure. If the outer ribs are wearing faster, increase the pressure.

How do you like the Nitto's?

 

there alright, if i had the extra cash i would have gotten the 555 or 550. i feel as though the car gets a little too slippery on the wet surface but handles well on dry pavement.

i live in seatlle so it's pretty wet most of the time...

i would recommend it to people living in dry climate...

 

i would personally never inflate my tires to that kind of PSI. Think of a tire like a basketball. The more that you inflate it, the more it bounces. Same thing with a tire. The more you inflate it, the more it bounces up and down, changes the ride quality, and wears the tire..........

 

uh, your logic is kinda wrong there, buddy.

basketballs BOUNCE...tires DON'T BOUNCE, they stay on the ground and roll. So unless you somehow get airborne, you don't need to worry about bouncing down the road like a basketball. The "bobbing" or how much a car "bounces" is mostly part of the suspension tuning/wear of the car, not the tires bouncing up and down off the road.

The only reason the ride quality changes is because the tires are now firmer, transmitting more road irregularities through to the car. but it does not "bounce" like a basketball, it just does not absorb as much irregularities when there is more pressure in it.

 

Kind in mind that although over-inflated tires will have better turn in responsive (or more responsive to steering change) in the dry, they will get very slippery in the wet.

 

From my experience, I like 1-2 psi higher at the back for that initial turn-in feel in a corner.
