I jut noticed today that one of my tires seem to be a bit low on air. What would be the most ideal tire pressure for every day driving? Would 25 psi be ok for my wheel configuration?

What the hell is a wheel configuration??


35-40 lbs. would be fine.

 

it should say somewhere in the fine print on the tire what the propper pressure should be, but yes, 35ish is ideal...

 

i been keeping the pressure at around 38 for ny roads,,,

I think he meant tire configuration ie going by the size of the tires. Regardless of the tires the ideal tire pressure is around 35 psi. It should say on your tires the maximum tire pressure if you happen to forget....

 

What's wrong with just running the pressure that's listed on your door jamb?

dont follow those numbers....if u do get ready for a realli big pop on hot days and hard driving (correct me if im wrong) but that what alot of places said

 

thanks for the replies guys. I put them at 35-37 psi and they handle potholes better than before

 

keep 5 psi below of the tire's max pressure.

 

read the label on the tires, it should state the max psi...

 

This is all kind of funny. For tire pressure regardless of what size tires you have wheather its a 14" or 24" you should run between 30-32psi of air. For road race or solo events up it to 35-38psi in the front ONLY.

As for keeping it 5psi lower then the max your asking for trouble. Keep in mind that when driving on the freeway for more then 20min the air in you r tires is going to expand about 25-30% So if you max tire pressure is 45 and your set at 40psi then once you have been on the freeway for a long period of time your already above that max. 30-32psi will give you the best compromis of wear, tread life, and handling. If your going to Drag race and want to hook up then drop it to say 20-25psi this will help out emmensly.

What he said

 

I must disagree. In conditions where it is extremely cold you may need to add more. Shouldn't it also depend on max PSI?

this is what the guy down here who repairs wheels tells all his customers. But what you said makes perfect sense..I'm going to go with you.

 

Yeah, as Turbowa said, around 32psi is best for daily driving conditions. My tires list a max pressure of 50psi, and I assure you, there's no way in hell I'm going to run 45psi in 'em. I run about 32psi, and my tires have always worn evenly. (They're also 215/45/17)

BryonC17, when outside temperatures go from warm to cold, the only reason you need to add more air to your tires is to keep the pressure around 32. The max pressure on the side of the tire is just a statement of the limitations of the tire.

Max PSi has absolutly nothing to do with what your tire psi should be set at. All that numbe ris is the safest recommended air pressure for that particular tire. Look at it this way you cars factory tires probably say there mar is around 45psi. Now take a tire of the same size and make but different maker and they put that there max psi is around 180psi. Now woul you want to run close to that number, NO because the car was not designed for it. Or for another comarison most accords come with the mich. mxv4 plus that have a max psi of 45 on the side wall. Honda recommends between 30-32psi of air. Now this same tire is used on the mercedes benz c230. MB recommend this tire be inflated to 25-28psi of air pressure. Same exact tire same max psi of 45psi, just on different cars but each car maker has a different preference on were there car will perform better.

And yes to an extent you want a little more air in extream cold. But were talking like extended periods below 10-15 degrees F. Even at that you only want to run about 2-4 extra psi of air because the tire can't come up to operating temp. at those extream temp's.

 

has it not occurred to you that these national or international tire companies, with vastly more resources than you will ever have, didn't just FORGET to take into account that air expands when you drive on the freeway? of course they didn't! the numbers on the tire are there for a reason. the manufacturers are not going to put an inaccurate number on there. that would result in a lawsuit. the best pressure for YOUR situation may not be that number but it should be safe to run any pressure within the specifications laid out by the manufacturer.

 

Like I said, what about running the number on your door jamb.

My jamb says 29 psi. This number takes into account your car weight, fuel economy, and ride quality. This is the number I believe you should shoot for instead of the max pressure listed on the tire. (just make sure your tire is at least 6 psi under the max when cold.)

 

funny how i came upon this today. in auto class, we learned alot about tires today. this very question came up. my auto teacher (who is about 50+ years of age and very knowledgeable) said to stick with the numbers on your door jam, it doesn't matter what size tire you have. but when it comes down to hardcore driving (hitting the turns all the time) you should mess around a bit to see where you get most traction from the tires, not neccessarily lower or higher, but to where it will work best. measuring tire PSI should be done when the tires are COLD btw

setting the psi too low or too high can cause premature wear. but like someone said earlier, IMHO i think 30-32 PSI is a good pressure for spirited driving like we all do here.
