what pressure should use front and rear? I have an R on 16's.

thanks.

 

Uhhh what does it say on the tire?

 

first you have to find Type-R air.

I have some for sale. $36.00 per LBS.

dumbest question ever. Look at the tire. thats the MAX psi. go from there.

 

The factory recommendation for stock 195/55/15 tires is something like 34-35 front and 32 rear.

I'd start with something like that and adjust to your liking.

I like 45 hot, what about you

 

I've still got a nail in my left rear.
Time for summer tires and some work on my car in another few weeks.

Que? 35 Front, 35 rear.

I use the same on the street with my 16's.

Has anyone checked their owner's manual?

I'm sick, in my PJ's and don't feel like leaving the appartment to check my glove box/doorjamb.

 

sorry but what does the max psi have to do with anything?

i suggest 32 psi as a general, and then adjust higher or lower from there to your liking.

well for starters it the maximum pressure your tire should be at. But most people like them in the mid 30's. I am just saying, he should know where to adjust tire pressure. or coulda searched about it. Start with the max and work down till you find something you like.

In the winter you should be at max psi and in the summer(warmer weather) you can lower it to your liking. Just my $0.02.

Someone feel free to correct me if I'm wrong.

 

This is where I have to appologize for jerkin around with Ed.

You Never start out with Max PSI.

Low 30's is generally accepted by many tire shops as a starting point since it is the cold pressure that many passenger car tires are suggested to operate at.

This is from Vulcantire.com :

"Proper air pressure makes tires wear evenly, prevents tire failure and increases handling and traction. While air pressure is responsible for the great task of supporting the weight of your vehicle, it is an easy aspect of your vehicle to maintain.

Inflation pressure is affected by changes in temperature. Because of this, the most critical times to check your pressure are in the fall and early winter months. For every ten degree Fahrenheit decrease in temperature, your tire's inflation pressure will decrease by approximately one psi (pound per square inch). Similarly, a ten degree increase will cause a pressure increase of one psi.

Since tires generally lose about one psi per month, it is important to check them regularly and often. You should be able to find the recommended tire pressure for your vehicle in the owner's manual or on your tire information sticker. Keep in mind that the tire pressure listed is a "cold" pressure. This means it should be checked in the morning before the car has been driven. Also, remember if you check your pressure inside an attached or heated garage, you will lose pressure when you enter the colder air outside the garage. Add 1 psi for every ten degree difference in advance to account for the temperature change."

And more from the Tirerack.com:

"Your tires support the weight of your vehicle, right? Well, they don't! It's the air pressure inside them that actually supports the weight. Maintaining sufficient air pressure is required if your tires are to provide all of the handling, traction and durability of which they are capable.

However, you can't set tire pressure...and then forget about it! Tire pressure has to be checked periodically to assure that the influences of time, changes in ambient temperatures or that a small tread puncture have not caused it to change.

The tire pressure recommended in your vehicle's owner's manual or tire information placard is the vehicle's recommended "cold" tire inflation pressure. This means that it should be checked in the morning before you drive more than a few miles, or before rising ambient temperatures or the sun's radiant heat affects it.

Since air is a gas, it expands when heated and contracts when cooled. In most parts of North America, this makes fall and early winter months the most critical times to check inflation pressures...days are getting shorter...ambient temperatures are getting colder...and your tires' inflation pressure is going down!

The rule of thumb is for every 10° Fahrenheit change in air temperature, your tire's inflation pressure will change by about 1 psi (up with higher temperatures and down with lower).

In most parts of North America, the difference between average summer and winter temperatures is about -50° Fahrenheit...which results in a potential "loss" of about 5 psi as winter's temperatures set in. And a 5 psi "loss" is enough to sacrifice handling, traction, and durability!

Additionally, the difference between cold nighttime temperatures and hot daytime temperatures in most parts of the country is about 20° Fahrenheit. This means that after setting tire pressures first thing in the morning, the vehicle's tire pressures will be almost 2 psi higher when measured in the afternoon (if the vehicle was parked in the shade). While that is expected, the problem is when you set your vehicle's tire pressures in the heat of the day, their cold pressures will probably be 2 psi low the following morning.

And finally, if the vehicle is parked in the sun, the sun's radiant heat will artificially and temporarily increase tire pressures.

We put some of these theories to the test at The Tire Rack. First, we mounted two tires on wheels. We let them sit overnight to equalize and stabilize their temperatures and pressures. The following morning we set them both to 35 psi. One tire and wheel was placed in the shade while the other was placed directly in the sun. We then monitored the ambient temperatures, tire temperatures and tire pressures through the day. As the day's temperatures went from 67° to 85° Fahrenheit, the tire that was kept in the shade went from our starting pressure of 35 psi to a high of 36.5 psi. The tire that was placed in the sun and subject to the increase in ambient temperature plus the sun's radiant heat went from our starting pressure of 35 psi to a high of 40 psi. In both cases, if we had set our tire pressures in the afternoon under the conditions of our evaluation, they would have been between 2 and 5 psi low the following morning.

Next we evaluated the effects of heat generated by the tire's flexing during use. We tried to eliminate the variable conditions we might encounter on the road by conducting this test using our "competition tire heat cycling service" that rolls the tires under load against the machine's rollers to simulate real world driving. We monitored the changes in tire pressure in 5-minute intervals. The test tires were inflated to 15 psi, 20 psi, 25 psi and 30 psi. Running them all under the same load, the air pressure in all of the tires went up about 1 psi during every 5 minutes of use for the first 20 minutes of operation. Then the air pressures stabilized, typically gaining no more than 1 psi of additional pressure during the next 20 minutes. This means that even a short drive to inflate your tires will result in tires that will probably be "underinflated" by a few psi the following morning.

Add all of these together, and you can understand why the conditions in which you set your vehicle's tire pressures are almost as important as the fact that you do set it.

It's important to remember that your vehicle's recommended tire pressure is its "cold" tire inflation pressure. It should be checked in the morning before you drive more than a few miles, or rising ambient temperatures or sun's radiant heat affects it.

And by the way, if you live in the North and park in an attached or heated garage you will "lose" pressure when you leave its warmth and venture into the real world outside during winter. Add 1 psi "cold" pressure tire pressure to compensate for each 10° Fahrenheit temperature difference between the temperature in the garage and outside."

 

see its all your fault!!! PS I never have left my tires at max psi cept one time at the track to have as little tire touchign the road as possible, then the next run i deflated them to 38 again. But its still ALL YOUR FAULT!!

A little birdy told me that it's actually 35F, 33R. I checked my manual, 35/33 is listed the manual for a 98 ITR.

 

your manuals wrong!!!!

thanks for the dumbest answer ever.

thanks for the serious answers, i just wanted second opinions. Most guys i know use around 32-35 i think but i wasn't sure if I should be using different pressures in winter to summer. i'll try 35 33 and see what a difference it makes.
