Tire Preassure For Summer

Hi guys,
Did u guys changes ur tire pressure when it was summer?Coz I noticed my ride was kinda bumpy then usual and I was thinking it was because of the weather changes affecting the air pressure.

I usually put 42Psi on my tire (225/40/18) when it was hot, because I know when it cold it went to 40Psi. Any suggestion?

I've never heard of changing tire pressure for summer or winter..I would think the temperature would most be determined by road friction....Unless your in a place where it freezes or gets extremely hot.....But your in So. Cal.? Who knows

I have 225/40/18's and I do 42 PSI year round. Sometimes 45 if they look saggy.

hm...45?doesnt that way too much for 225/40/18? I've been told the max is 40, its getting pretty hot here in socal, I just feel that my ride was more rough then usual so I was thinking it 's prolly from the tire preasure....

Can anyone tell what's the point of setting pressure THAT high on different tire sizes?

Tire pressure depends on the weight of the car and it's always recommended to stick to the original pressure provided by the manufacturer. If you get wider tires then yes you may want to add 2-3 PSI just so low speed steering doesn't feel too hard but otherwise going 40-45 PSI on COLD tires is only asking for 1) back problems, and 2) blown up tires. And with the light steering wheel the Accord has is also asking for accidents.

To the OP, I would suggest checking your pressure at least once a month and always set COLD pressure, never try to change tire pressure when you've driven the car 20+ minutes or at higher speeds. It doesn't matter if it's summer or winter, you will notice a drop in pressure on colder days and it might increase when summer comes but just pick the pressure you want and only check/set the next morning.

I set front at 32PSI and rear at 30PSI, that's stock settings on 225/50-17. After 30-40 minutes of driving it easily hits 40PSI and when it's really hot it goes even higher.

I am with you on this. I really dont get putting that much air in a tire when the manufacturer recommendation is what you should be putting in. Anything other than recommended pressure is a guessing game. The reason the car rides so harsh is because the tires are like rocks after heating up. They are probably over max pressure when hot.

when i had my 19 i used to put 42psi cause in the north east theres alot of pot holes . ive seen a lot of rims get bent or tires get bubbles cause the tire was easily pinched .

Your logic's skewed. Imagine 2 extremes. Say 28's or better yet, semi wheels/tires, I doubt 32 psi will cut it. Imagine some 5in go-kart wheels. Not an expert but I'm gonna guess 32 would likely blow one out. On my 18's, if I do 32, they look near flat when tires are turned in, the rim could easily hit a small pothole like that.

I realize that an aftermarket tire may need different tire pressures. An easy way to take the guess work out of it is the chalk method....Get a piece of chalk and draw a line across the face of the tread around to the side on each tire. Drive on a nice flat surface for about 50 feet, then look at each chalk mark. If more chalk is gone in middle tire tread, the tire is over inflated. If more chalk is gone on the outer portion of the tread then it is under inflated. Once you get the tire pressures to where the chalk is showing even wear, note the pressure you are at, then use that pressure. Doing this while the tires are cold or warm doesn't matter as long as you always check the pressure at same tire temp as when you did the chalk test.

I'm pretty sure the pressure on the sidewall is the max pressure, not the optimum pressure. The stock tires on the accord were 32 front and 30 rear, but on my 18's that was too low. I'd notice the sidewalls would be hot after a freeway run. I just increased the pressure until the sidewalls didn't get hot. I think it came out to 38 front and 36 rear.

What is on the side of the tire is max pressure at max load. Most passenger cars under normal cicumstances never have a max load condition. The max pressure is also a temporary pressure for towing, heavy loads, etc...

The problem with using that much pressure is that if you use that pressure when cold, then they most likely going over 50psi when hot. Not only is this potentially dangerous, but your tires will most likely wear unevenly and you are not getting as good of traction as you could because the tread contact is not what it should be. A good example is: It is alot easier to spin your tires with higher tire pressure than it is with a lower pressure. Why do you think in drag racing, they reduce the drive wheels air pressure to get maximum traction?

I'm sorry I didn't explain at first that I'm talking about after market tire and wheel, where there is no such thing as Honda suggested pressure on these (the one printed on the side door was for OEM steel wheel) however I did contact Falken and they suggested 40PSI for this tire size, I'm supposed when its cold. I just inflate the tire to 43PSI when its hot yesterday, it ride better now.

PS:I did it when its hot because I did it on the gas station

True, thanks for pointing that out! If you choose to get tires with that low of a profile on a heavy car like the accord which requires tires with bigger sidewalls for normal daily driving I imagine you would need to compensate and increase the tire pressure. Mostly for the fact that it's a daily driver used on normal roads (with potholes and such).

What causes your tires to look near flat is the weight of the car.

The 40psi they told you is checked when cold. That is normal practice.

Falken gave you a recomendation on the tire size. Remember inflation pressure is also based on each individual car. The 40psi is a good starting point. Remember the weight ratio on our cars is 60f/40r, that is why the stock inflation pressures listed inside the door are different from front to rear. 40 may be good for the front but a little too much for the rear.

If you are really curious, try that chalk test I mentioned in an earlier post. It is a good way to take the guess work out of it, and get some improved traction and tire wear.

My tires are worn completely even and when I decrease the pressure to 35-40 the steering is just too mushy and unresponsive. The tires look flatter also. I like the feel of 40+ but most of the time when I check the tire pressure when cold it is 40, I get tired of refilling them every two weeks but when I do refill I go back up to 44.
