Hello All. Ahhh glad I found this site. I'm a new TSX owner (new 2006 bought in August 2006) and I'm wondering about tire pressure. I know the car states 32 PSI in the front and 30 PSI in the back. I used to have an Accord and I kept all 4 tires at 35 PSI.

Any thoughts? Is it wise to have different pressure between the back and front? Should I keep all 4 consistent at 35 PSI? Would that harm the car at any way?

Thanks.

 

search for huge thread on this. everyone lists their tire pressures. I think i keep mine at 35 front and 33 rear

 

34 for all of them. I already have enough numbers to remember.

 

No, but the car will ride better with the recommended pressure.

Tire pressure is a compromise between several factors:

(1) Overall ride smoothness. Lower pressure helps soak up small irregularities in the road surface.

(2) Tire wear. Higher pressure = longer tire life, within limits

(3) Handling. Higher pressure = less sidewall flex = better cornering, within limits.

Overinflating a tire can cause a strange wear pattern in the tread -- the center wears but the edges don't -- which can also adversely affect handling and ride in the long run. I don't know if 35 psi is enough to cause trouble, but certainly anything much over this will. Also, a radial tire needs a contact patch of at least a certain size for proper handling, so at some point raising the pressure will make handling worse rather than better.

Note that the front wheels bear 60% of the weight, so it makes sense to put a PSI or two more in the front tires to have a uniform contact patch between the front and rear.

The TSX already has a very firm ride, so I personally am sticking somewhat closer to the recommended pressures (like 34F, 32R).

 

i just add 3 psi per tire on top of recommended value

 

Thanks all for you comments. This place will be very useful to me (novice when it comes to cars).

 

Do you ever notice that the tire looks flat when you look at it from the side? Or am I just being too self concious.

 

You just have to trust your tire gauge on this. Appearance isn't always a good indicator of the tire's pressure. Welcome to AZ.

 

Yes, radial tires have a characteristic sidewall bulge that is perfectly normal.

Cool thanks. Just wanted to make sure. Any other advice to keep the tires in good condition, I'd greatly appreciate it.

 

Wash them along with the rest of the car. You may or may not want to put some sort of tire shine or gel on them. You may want to look in here for more.

Welcome to AZ!!

 

If you dont know what effect a decrease or increase in tire pressure does, then why on earth would you do anything then what the manual (or whats printed on the side of the drivers door) says?

 

35 front, 33 rear

 

^^^ Me too...

 

^^ You guys are waaaaaaaay off. Its 36F, 34R

 

oh yeah 007?

what gas mileage do you get?

 

^^ around 25city, 32hwy, 27combined. Last long trip I took I pumped up the tires to 38/36 and went 514 miles on a tank (34.7mpg)

 

hmm come springtime, i'm going to put them up to 38/36. only bad thing is the ride will get stiff.

 

Do you all add air to ur tires at gas stations or do you have one of those machines at home?

 

34 all around

 

Actually I found the best setting for my new Yoko's was 35.5/33.5 but the changing outside air temp kept f'ing with me.

 

, that's perfect. Once your tires warm up you'll be 36/34.

Yup, I check it about once a month. The gas station where I go provides free air if you fill up your tank (the savings allows me to be able to afford 91 octane gas)

 

Good one!

 

Wow, once a month? I try to check mine once a week - and I'm often down 1-2 psi per tire every time I check...

Oh, 36F/34R in the Winter and 34F/32R in the Summer.

 

&deity. bless the Tire Pressure Monitoring system in my new TSX.

 

I check mine about every 3 months. How could tire pressume come down that fast? Do you have a leak? Does it normally do that?

 

Are you talking about for the 2007? Darn, just missed it by one year.

 

Yes. Initially I thought it was a gimmick (or was just like other systems that just tell if you if a tire is low based on diameter reduction ) and didn't care one way or another, but it's pretty cool.

The computer sensors read the tire pressure within about 1 PSI of my gauge and you can see them on the information display in the instrument cluster.

 

hello boys. well i did the search before posting a new thread and came up with this thread.

i have a tire pressure question. i just hope someone is able to guide me the right way . if so, i'll owe you all a big one

i'm in northern va and yesterday the temp was at 65 degrees. i put my pressure to 35 psi. now it's about 85 degrees and i just came back from lunch. i checked the tire pressure and it was up to 39 psi. is that bad?

should i lower it some? i know you should put air in when the tires are cold. yesterday they were cold and placed it at 35 psi (once again, temp was 65 degrees). now that the weather is starting to get hot, should i lower the pressure so that when i drive it won't go up that high?

and with a high tire pressure, could things go wrong?

thanks you all.......

hey, how you doin

anyways, yes that is bad, you should put it at 34 front/ 32 rear, which is what I have it at. the recommended tire pressure is 32 front/30 rear, but don't put it past 35 or 37 because it will produce uneven tire wear.

 

Make sure it's a good gauge too! I didn't realize the difference until I bought a $35 BMW tire gauge on the recommendation of several people I know. All I can say is, WOW! I'll never go back to cheap gauges again.

I'd recommend a dial gauge, with a pressure release button, and a rubber coating...they may cost, but if well made will last years and years!

On tire pressure...a 10 degree temperature difference will raise the tire pressue about 1 degree or so...plus if the car is sitting in the sun, the tires in the sun will have higher pressure too. Don't rush to let air out...make sure all tires are cool and check then!

 

Im running 40psi front, 38psi back on my toyo proxes 4

 

^^^+1 on my 225/40/18 P-Zero Neros.

 

Measure your tire pressure in the morning before you ride your baby....cuz air will expand while you drive, and get higher psi.....or during day time......samething...
since it's summer, some of you might want to adjust.....

 

see when it's cool, it's not past 35 or 37. when the tire is cool (morning) or before i leave for work (car in garage all day), the tire pressure is at 35 psi. it's when i drive in the hot summer, that's when it goes up to 39.

so should i lower it to 33 or 34? thoughts? or keep it at 35 psi (cool)? does it do a lot of damage to the car OR tire if it goes up 2-3 psi during driving?

 

i think the temp in va from now on will be in the 70's to 90's. when i filled the tire up with air (tires cold), it was 65 degrees and i filled it up to 35 psi. now should i just lower it 1 psi?

all 4 tires have the same pressure. there are so many things out there that i have to remember that i just want to keep all 4 the same.

 

Mine are 19 Front Left, 34 Front Right, 30 Rear Left, 23 Rear Right. they may vary 1 or 2 points depeneding on how hot it is outside.

 

A tire gauge from a store measures tire pressure compared to outdoor pressure.

The store tire gauge will read different pressures at sea level compared to +5,000 feet, warm afternoons with lighter air compared to cold mornings with heavier air and cold tires compared to hot tires.

It is good to have a gauge and double check your pressure before/after driving in different condtions. Chances are the TPMS on 07s may be more accurate than the most expensive tire gauge because the TPMS on the TSX measures the tire pressure inside the tire only.

 

What he said. It all comes down to your tolerance. If you can stand a stiffer ride and want better handling, bump the pressure up in increments, within limits, until you find a happy medium between ride and handling.

BTW, it's always more dangerous to underinflate a tire than overinflate it, within reason of course, which is why you always set tire pressure to the coolest time of day.

 

Just out of curiosity, has anyone living in an area with wild temp differences (like me in Arizona) had the Nitrogen fills on their tires? Due to molecular size, it is supposed to leak out less. My morning air temp can be 80-85, and my afternoon air temp can be 115, so any help is good. Just wondering if anyone has compared the amount of gas loss from air to pure Nitrogen?
