is 32psi good enough in all 4 or should i put more air?

[talontsiboy24]

I have a 92 eagle talon awd just wondering if 32psi in all 4 tires is good or should i put more air in? i only street drive the car no track stuff but of course we all like to get on it on the streets to.

 

[ilco187]

yeah thats what i use.

 

[DSMDriver69]

if its says 32psi on the tire, thats what you should use.

 

[hhuricane]

if its says 32psi on the tire, thats what you should use.

No, that is the maximum pressure the tire can be set to. Recommended pressure for AWD is 32 in the front and 29 in the rear. FWD is 29 front and 26 in the rear. Check the label in the drivers door jam if you need to know.

I run 36psi on all 4.

 

[knochgoon24]

It all depends on the tire.

My last set needed 36psi in all 4 to handle reasonably on the streets and 40/42 (front/rear) for autox. The set I have now are fine at 34psi. The winter tires I had were ran at 35psi in warmer weather and 30psi in the colder weather to have them handle the same (winter compound got squishy in the warmth).

Just experiment with it a little bit. Watch the tread wear. If the centers start to wear faster than the outer edges, you may have too much pressure. If the centers don't wear as fast as the outer edges, you may have too little pressure.

Agreed. Try some different pressures to see what optimizes your specific tire brand and suspension setup.

More pressure=more responsive, less heat buildup, better fuel economy....

Less pressure=larger contact patch, softer ride/more comfortable, lower mpg....

I'm running 36psi for all 4. When I switch to a different make/model I'll try different pressures to find what works best with them.

yea i know thats what the door tag says but i dont have stock tires or rims i have 17" enkie rims and the max pressure on my tires is like 40 something so i think 32psi all around is fine...

well if stock calls for 32psi front 29 rear for stock rims and tires then id use that but i have 17" rims and tires and stock suspension so should i put in 34psi all around?

 

[romeen]

Again, just experiment with different pressures until you find what you like. Go ahead and do 34psi on all 4 and drive it around for a few days paying attention to traction, steering feel, responsiveness, turn in, etc. Then try lowering it to 30 or 32 and drive it around for comparison. Maybe bump it up to 36 psi next.

The recommended inflation pressure on the door jam tends to be on the low side (IMO) for performance driving. This makes the ride less harsh and might provide just a bit more grip. It's mainly for the "average joe" drivers, not enthusiasts.

One of the best places to mess around with tire pressures is at a local autox event.
Then you can really see how changes in tire pressure really affects handling.

 

[talontsiboy24]

the max my tires take is 51psi and im running 32psi in all 4 so i think that should be good cause when the tires warm up im sure the pressure will be higher then 32.

 

[ThomasG-1b]

I had 35 cold psi in all four then i droped too 32 cold. I see about 3-4 psi higher after getting to work. I saw about 1-2 mpg less but alot better turn in and corner control. The higher pressure was nice cause I drive about 20 miles to work every day at 70 mph so the feel was nice. The lower pressure feels kinda "loose" is the best way I can put it.

 

[talontsiboy24]

well i believe stock wheels are 15" on a 1g and the door label does say 32 front 29 rear but i have 17" rims with stock suspension so say i run 34psi in front does that mean i have to put 31psi in the back?

 

[talontsiboy24]

No, that is the maximum pressure the tire can be set to. Recommended pressure for AWD is 32 in the front and 29 in the rear. FWD is 29 front and 26 in the rear. Check the label in the drivers door jam if you need to know.

But 32 29 is for stock wheels 15" i have 17" and the tire size is 225/45-17. So does it matter if i upgraded to bigger rims?

 

[talontsiboy24]

Is it better to run lower tire pressure in winter time like 32 in all four?

 

[knochgoon24]

The reason the car says 32 front / 29 rear is because the fronts are loaded heavier than the rear. From the factory on factory tires, that pressure makes the contact patches the same "optimal" size. It's only going to be a ballpark number once you switch tires.
I ran higher pressure in my rears for autox because it made my car understeer a little less. But since my suspension is so worn out, those same pressures probably wouldn't work for you.

But with the winter tires, once again, you're going to want to experiment.
I can run a higher pressure in my tires when it's dry out so they don't feel like they're squarming everywhere, but I have to drop the pressure in the snow or the handling gets twitchy. Right now, they have 35psi in them. Once the roads have about an inch of snow on them, I'll take 5 min and lets some air out to drop them to about 30psi. Those numbers work for me, for my car, and for the tires that are on it.

As easy as it is to add or remove air from a tire, it's easier for you to just play with the pressures until it rides and handles like you want.

 

[talontsiboy24]

My car door label says 32front 29rear but thats what stock calls for with 16" wheels right? but i now have 17" rims and tire size is 225/45-17...its winter out here so i was thinkin to run 32 or 34psi in all four? They say not to run higher then stock pressure in winter and lower pressure makes better contact with the ground?

By the way my car wont be driven when snow is on the ground only on those dry winter road days but our temps are in the 20s,teens,and single digits out here.

 

[rx7ttlm]

since the hot pressures on say an auto cross or road race end up building more front pressure I actually start with the opposite I start with like 33/34 with advans.

 

[talontsiboy24]

But im saying the door lable says 32psi in front i guess cause the car is heavier in front then the rear? So i should probably put 34psi in front and like 32psi in the rear since im on 17" rims which are heavier then the stock 16s?
