Should I use 32 lbs on all tires?
I do 99% highway. I basically have one block of non highway driving per day.

Any opinion on this?
It's currently between 26 and 28 lbs.

 

If I'm not mistaken, I think 32 is what is recommended by the manufacturer.

 

That's why I thought 32 might be good.
However, I am asking for personal opinion on what you use and what you think would be good for mostly highway driving.

 

I noticed, when my car has more pressure in the tires, the car handles better (obviously), accelerates quicker, and moves easily on the highway. Also, I get better gas mileage. However, the ride is stiff with more pressure in the tires. If you do mostly highway, try 34 and if you dont like it go down to 32.

 

Well, more air in the tires means better gas mileage. I personally do a lot of highway driving and at a minimum keep the pressure at 32. I've been tempted to go as high as 36, but am somewhat reluctant to do so. I hope this helps. BTW, I haven't felt any ill side effects from keeping my tires at 32.

 

I believe the max suggested is 35, though I had it up to 45 for one tire for a few days because of a NAIL. (needed it to stay inflated for awhile longer)

So, the question of the day....should I try 34 or stick to 32?

I don't mind the stiffer ride.......I've been lucky enough to drive my wife's s2000 for the last 3 months. (tax season...her lose, my gain)
So, doesn't matter how stiff, it's still going to feel like a boat when I get in it.
I just don't want to have too much negative effects such as losing traction or simply blowing out the tires.

 

If you go up another pound to 33PSI it would not hurt.
I need to correct my pressure also in my tires.
I just changed back to the stock tires that came with the car from the winter tires last week. I could have kept the stock tires on because we had no winter at all. I most likely will put 33 PSI all around. The car just seems to ride better with 33 or 34 then 32PSI.

 

Damn, I was just getting ready to post this same very question.

Anyway, I just had new tires put on and they put the pressure to 35. I didn't check it until the morning after so I didn't get a chance to ask the tire guys if thats what they thought was best. I checked my hwy mileage and it was around 30 like it's always been (I have a TLS w/ 235/45-17 BFGoodrich g-Force KDWS -- used to be 225/50-17 Mich Pilot XGT Z4). I dropped the pressure down to 32 (where I normally keep it) because the ride seemed a bit hard. Maybe it's just the driving I've been doing since but my mileage seems to have dropped and the handling seems a little sloppier. I'm going to put them up to 34 tomorrow and see how it feels.

 

Thank you guys for all the comments.
I think I will give 34 a try

 

I believe someone posted a while back on how to get the optimum tire pressure as far as traction is concerned. Keep in mind that a bit too much tire pressure will cause the center of the tire tread to wear faster than the sides. You want to put in just enough air so that the entire width of the tread is in contact with the ground. Generally speaking, the more rubber that is in contact with the road, the more traction you'll have; of course, most people will want to balance handling and comfort, i.e., perhaps sacrifice a bit of traction for a smoother ride.

34 feels just fine so far.......

 

considering that most of the tires we have can handle a max pressure of beyond 40psi, I'd experiment. so far, I have 34 just for the heck of it cuz I hate it when my tires look like they're squatting and flat and it just makes no sense having 32 in a tire that can handle 45psi. and u know, I'd bet that u probably wouldnt even notice too much difference between 32 or 34 after a while. Its not like we're rounding curves on a winston cup race where half a pound of air makes a difference

 

I had 26-28, 34 feels quite different
The ride is good. I'll probably report back when I get the mileage.
